Luis Castillo Moving to the Bullpen
Chicago White Sox veteran right-hander Luis Castillo has been moved to the bullpen, manager Will Venable told Jesse Rogers of ESPN. Castillo, who was acquired by the White Sox from the Seattle Mariners at this year's trade deadline, has really struggled since joining the team, going 1-2 with a 7.76 ERA (6.30 FIP) and 1.79 WHIP with 25 strikeouts and 11 walks in 29 innings pitched across his seven appearances (six starts). The 33-year-old Dominican hurler has allowed 17 earned runs on 26 hits (five home runs) while walking seven and striking out nine in his last 13 1/3 innings pitched for Chicago since Aug. 22. Castillo just has not been good and will now finish out the 2026 campaign as a reliever for the Pale Hose as they look to close out the American League Central division. Overall this year, Castillo has gone 4-11 with a career-worst 5.67 ERA, 1.48 WHIP, and 111:43 K:BB in 128 2/3 innings pitched in 27 outings (23 starts) with the M's and White Sox.

Colson Montgomery Out With Wrist Injury on Thursday
Chicago White Sox infielder Colson Montgomery (wrist) is not in the team's starting lineup on Thursday against the division-rival Detroit Tigers and left-hander Framber Valdez, according to MLB.com. Miguel Vargas is playing third base and batting third, with Luisangel Acuna playing shortstop and batting eighth. Montgomery will sit this one out after being hit by a pitch on his left wrist on Wednesday, but thankfully, X-rays were negative, so he should be considered day-to-day for now. Fantasy managers will want to check back on Friday to see if the left-handed slugger is back in action for Game 2 of the series against Detroit in Chicago. The 24-year-old former 22nd overall pick in 2021 is hitting just over the Mendoza Line, has an on-base percentage under .300, and has struck out a league-high 211 times in 604 plate appearances, but fantasy managers cannot argue with his power. Montgomery has clubbed 31 home runs and driven in 84 RBI in 144 games after he hit 21 homers and drove in 55 runs in just 71 games as a rookie in 2025.

Tristan Peters a Strong-Side Platoon Bat Worth Targeting
Across 470 plate appearances in 2026, Chicago White Sox outfielder Tristan Peters is hitting .273/.343/.452 with 12 home runs, 54 RBI, 61 runs scored, and eight stolen bases. The lefty-swinger is hitting .192 across just 63 plate appearances against left-handed pitching, so his big-side platoon role limits his fantasy value to some degree. However, Peters owns an .824 OPS against right-handers and brings a balanced profile at the plate that allows him to provide modest production across all five fantasy categories. After hitting six home runs across 87 plate appearances in August, the 26-year-old has gone without a homer in his first 56 trips to the plate in September. Still, Peters hits for average and should continue to provide steady run production in stretches where the White Sox face a string of right-handed starting pitchers. Heading into the final week-plus of the regular season, Peters could be worth targeting as an outfield streamer off the waiver wire.

Colson Montgomery Leaves Early With Wrist Contusion
Chicago White Sox infielder Colson Montgomery (wrist) left Wednesday's game against the division-rival Cleveland Guardians with a left-wrist contusion, according to the team. Montgomery is being further evaluated after he was hit by a pitch in the fourth inning. In addition to being hit by a pitch, the 24-year-old left-handed slugger walked before being replaced at third base by Miguel Vargas, who moved over from first base. Munetaka Murakami entered the game to play first base. Montgomery, the 22nd overall pick in 2021, will likely undergo X-rays to rule out a fracture in his wrist. A significant injury at this point in the season could make Montgomery unavailable for the postseason next month, which would be a big loss for the Pale Hose. Montgomery came into Wednesday's contest hitting just over the Mendoza Line in his first full season in the majors, but he has also contributed 31 home runs and 84 RBI in his 144 games. The young infielder has 51 homers in his first 214 big-league games, making him a must-roster player for his power from the left side. If his injury is not serious, Montgomery could return as soon as Thursday's series opener against the division-rival Detroit Tigers.

Mathias LaCombe to be Promoted to Triple-A
Chicago White Sox pitching prospect Mathias LaCombe will be promoted to Triple-A Charlotte following a strong finish to the Double-A campaign. The right-hander recorded a 1.12 ERA, 0.75 WHIP, and an 18.5 percent K-BB% over his final 12 appearances (16 innings pitched) for Birmingham. The former 12th-rounder got a late start to his season due to shoulder discomfort, but showed well in 16 appearances at High-A, which propelled him to a promotion. Due to the late start, the organization is sending the 6-foot-2 hurler to participate in the Arizona Fall League for some additional exposure. The French-born prospect has some strikeout potential if he can refine his fastball/slider/splitter mix, but doesn't have prototypical closer stuff, and unless Chicago converts him back into a starter, the 24-year-old will be off the fantasy radar to begin next season.

Pierce George Headed to Triple-A Charlotte
Chicago White Sox pitching prospect Pierce George is expected to be promoted to Triple-A Charlotte, his third promotion this year. The right-hander began the season at Single-A, earning promotions to High-A and Double-A, the latter of which is where he posted a 4.91 ERA, 1.36 WHIP, and an 11.0 percent K-BB% in 33 innings as a reliever. The 6-foot-6 hurler features a high-90s fastball that can touch triple digits, and although he had some control issues last year (19.3 percent BB%), he improved that greatly this season, lowering his walk rate to a palatable 10.3 percent. Chicago is also sending the right-hander to the Arizona Fall League for some additional work, so they may envision him being part of their bullpen as early as next year. While all that is good, Chicago's 19th-ranked prospect isn't on the dynasty radar at the moment and likely won't be on the redraft radar unless he makes a push for the closer role on the South Side.

Miguel Vargas Showing Off Increased Speed in September
Chicago White Sox corner infielder Miguel Vargas has been one of the breakout success stories of the 2026 season, hitting .249/.358/.475 with 31 home runs, 84 RBI, 98 runs scored, and 19 stolen bases across 658 plate appearances. The 26-year-old's underlying metrics largely support his power emergence, as he's posted a 13.4% barrel rate and a 44.2% hard-hit rate. Vargas also offers an elite approach at the plate, logging a 13.7% walk rate while striking out in just 17.9% of his plate appearances. Vargas has also significantly boosted his aggression on the basepaths in recent games, going six-for-six as a base stealer in September. Heading into the final stretch of the regular season, Vargas profiles as an elite option at either third or first base for fantasy managers.

Grant Taylor a Worthy Waiver-Wire Target
Chicago White Sox right-hander Grant Taylor has been one of the breakout success stories of the 2026 season, recording a 7-2 record with a 2.16 ERA, 1.04 WHIP, and 97 strikeouts across 75 innings (55 games). The 24-year-old is averaging 98.1 miles per hour on his fastball and has paired an excellent 32.4% strikeout rate with a manageable 8.7% walk rate. Given Taylor's utility to the White Sox as a high-leverage fireman who can work more than one inning, the team has not deployed him as a traditional closer. Still, he's racked up eight saves this season and remains a threat to take over the full-time closer role in Chicago at any point. Even if Taylor's usage remains the same down the stretch, he provides value to fantasy managers as a high-end source of ratios and a better source of strikeouts and wins than most relievers.

Sean Burke Gets Start Moved to Tuesday
Chicago White Sox starting pitcher Sean Burke had his scheduled start against the Minnesota Twins on Sunday moved to Tuesday, according to Scott Merkin of MLB.com. Instead of facing the Twins this weekend, the White Sox have decided they'd rather have Burke pitch against the Pirates on Tuesday. The team has yet to name a starter for Sunday's series finale against the Twins. Since the All-Star break, Burke owns a 2.76 ERA, 1.08 WHIP, and a 52/21 K/BB ratio across nearly 50 innings of work. The White Sox may be trying to limit his workload over the final month of the season.

White Sox Reinstate Kyle Teel From Injured List
The Chicago White Sox announced on Friday that they reinstated catcher Kyle Teel (ankle) from the 10-day injured list and optioned catcher Drew Romo to Triple-A Charlotte in a corresponding move. Fantasy managers will want to check back a bit later on Friday to see if Teel is immediately back in Chicago's starting lineup for Friday's contest at home against the division-rival Minnesota Twins and right-hander Zebby Matthews. In six minor-league rehab games, Teel went 7-for-22 at the plate with a home run and a double. He will be rejoining the big-league squad after landing on the IL early in the second half of the season due to a sprained left ankle. Injuries have limited the 24-year-old former first-rounder by the Boston Red Sox to just 19 games and 63 at-bats in 2026 in his second year in the big leagues with the Pale Hose. In those 19 games, Teel has gone just 12-for-63 (.190) with two home runs, 14 RBI, nine runs scored, six walks, and 27 strikeouts. Despite the poor start in a limited sample size, Teel should play regularly down the stretch and has more offensive upside than the other catcher on Chicago's big-league roster, Jake Rogers.

White Sox Call Up Pitching Prospect Tanner McDougal on Tuesday
With rosters expanding on Tuesday, the Chicago White Sox called up right-handed pitching prospect Tanner McDougal from Triple-A Charlotte, according to the team. The 23-year-old former fifth-round selection in 2021 made his major-league debut for the Pale Hose on Aug. 13 against the Cincinnati Reds and allowed an earned run on three walks in just one-third of an inning. The team's seventh-ranked prospect, per MLB Pipeline, went 1-2 with a 4.57 ERA, 1.40 WHIP, and 47:27 K:BB in 41 1/3 innings pitched across 22 outings (six starts) for High-A Winston-Salem and Charlotte this year. The 6-foot-5, 185-pounder has not exactly been dominant in the minors in 2026, so he is unlikely to have anything more than a low-leverage role out of the bullpen for the White Sox in his return to the Show in the final month of the regular season. McDougal does feature a high-90s fastball that touches triple digits, and he really knows how to spin his breaking pitches. The pure stuff is intriguing, but McDougal still needs plenty of refinement with his command and control.

Tristan Peters a Priority Waiver Target Amid Ongoing Power Binge
Chicago White Sox outfielder Tristan Peters is somehow rostered in only 31% of Yahoo leagues, despite homering in each of his last five games. During his five-game homer span, Peters has gone 10-for-18 (.556) with five home runs, two doubles, nine RBI, seven runs scored, and a stolen base. The Canadian outfielder is now slashing .282/.346/.475 on the season with an .821 OPS, 12 home runs, 52 RBI, 53 runs scored, and seven stolen bases in his 358 at-bats in his first year with the Pale Hose and his first full season in the majors. He debuted in 2025 with the Tampa Bay Rays but played in just four games. Even if Peters regresses in the final month of the season (he is sporting a .255 expected batting average and .315 xwOBA), the left-handed slugger should no longer be ignored while he's white-hot at the plate for Chicago. Peters has hit .349 (22-for-63) with a 1.169 OPS, six homers, six doubles, 14 RBI, 13 runs scored, and two stolen bases in 23 games in August, but he's hitting .159 (7-for-44) with only one of his 12 homers on the year against southpaws.

Caleb Bonemer Showing Off Power Stroke in 2026
Chicago White Sox infield prospect Caleb Bonemer is not only fitting in at Double-A Birmingham, he's excelling, too. Chicago's second-ranked prospect is hitting .268, which is 30 points higher than his average was at High-A, while reducing his strikeout rate by more than four percent and drawing a few more walks. It has resulted in a .962 OPS with 16 home runs in 55 games for the Barons, and combined with his 18 home runs from High-A, the former second-rounder has now blasted 34 home runs on the season, including four in his last six games. While he isn't known for his speed, the 6-foot-1 slugger has also tallied 16 steals between both levels, providing strong all-around production. The right-handed hitter should see time at Triple-A in 2027 and could be in the mix for a second-half call-up to the majors, so redraft managers should be familiar with the name.

Kyle Teel to Begin Rehab Assignment on Monday
According to Scott Merkin, Chicago White Sox catcher Kyle Teel (ankle) is set to begin a minor league rehab assignment with Triple-A Charlotte on Monday. Teel has been out since late July due to a left ankle sprain. He has progressed quickly and is cleared for the final step of his rehab program. The expectation is that Teel won't need more than a few games before he'll be ready to rejoin the White Sox lineup. He should return as the No. 1 catcher once he's back in the mix, which will mean reduced roles for Drew Romo and Jake Rogers. Teel could be worth stashing in deep leagues for fantasy managers needing help at the catcher spot.

Roch Cholowsky Shut Down for Rest of Season
According to James Fegan, Chicago White Sox shortstop prospect Roch Cholowsky (wrist) has been shut down for the year. The No. 1 overall pick from this year's draft is done for the season due to right wrist soreness. Across nine games with High-A Winston-Salem, Cholowsky went 6-for-36 with a home run and 10 RBI, and seven walks. He'll likely return to this level next year, but it shouldn't be long before he gets promoted to Double-A. The expectation is that Cholowsky should be on a relatively quick path to the big leagues.
