June 3, 2026

Dan analyzes 6 must-add fantasy baseball waiver wire pickups, mid-week adds for Week 10 of the 2026 MLB season. Grab these players asap off the waiver wire.

Happy Wednesday, RotoBallers! If your fantasy baseball league offers daily or semi-weekly transactions, the mid-week edition of Must-Add Waiver Wire Pickups for Week 10 of fantasy baseball is here to help set you up for success this weekend and beyond.

I usually shy away from players who carry a high strikeout rate, but in this week’s group, you will find four hitters that share that trait. I’m comfortable jumping on them now, as the circumstances surrounding each are increasingly favorable, at least in the short term. Bringing up the rear are a pair of starters from the Dodgers, who have enjoyed some recent success.

As always, the players featured in this column will be available in at least 50% of Yahoo leagues. If you need more waiver wire advice, reach out on X (@danifestmestiny) or Bluesky (@danifesetmestiny.bsky.social). For now, keep on reading to find out my favorite Must-Add Waiver Wire Pickups for the rest of Week 10 of the fantasy baseball season.

2026 Fantasy Baseball: Mid-Week Waiver Wire Adds

Jac Caglianone, 1B/OF, Kansas City Royals

The sixth overall pick in the 2024 draft, Jac Caglianone hit .419 and 35 home runs for the University of Florida that year. His 75 homers in a Gators uniform set a school record. Caglianone demolished minor league pitching in 2025, slashing .337/.408/.617 with 20 home runs in 66 games across Double-A and Triple-A.

While there is no denying that Caglianone is one of the more prodigious power prospects in recent memory, I’ve been slow to take a shine to him. The Royals really rushed him through their system, and he seemed in over his head after his MLB debut last summer. His first year of action in the majors ended with a .157 batting average and seven home runs in 62 games.

As the weather warms up, so too do my feelings towards Caglianone. He is catching up to big league fastballs and seeing offspeed stuff better, too. Last season, he hit .163 against fastballs and .146 against offspeed pitches, and this year he is hitting .294 and .269 on those mixes, respectively. Caglianone also features a gaudy 15.7% barrel rate and one of MLB's highest hard-hit rates (57.9%).

Next on the docket for the Royals is a four-game series against the Twins, meaning an extra day of action for Caglianone, followed by a series against the Rangers and then the Astros, all of which will be played at home. Each team's pitching staff features low ground ball-to-fly ball ratios, and Texas and Houston in particular are prone to giving up home runs.

If Caglianone sees the ball well in the next week or so, he could add a few more home runs to his tally this season.

Kerry Carpenter, OF, Detroit Tigers

After a promising 2024 was cut short by injuries, Kerry Carpenter looked like he was on the cusp of taking another step forward in 2025. Unfortunately, the injury bug bit him again, limiting him to 130 games. That the outfielder was able to mash 26 home runs in that span after hitting 18 in roughly half a season the year before made a good case that he was turning the corner to becoming a trustworthy resource in fantasy baseball.

Carpenter got off to a cold start in 2026 and then, once again, landed on the injured list on May 10 due to an AC joint sprain. Carpenter had an underwhelming triple-slash of .216/.299/.450 and just 17 RBI when he hit the IL. The 28-year-old was activated on May 31 and started June with a home run, his seventh of the season, while going 3-for-5 against the Rays.

Carpenter’s splits dictate that he is best used in a platoon role, but that may be for the best as he thrives against right-handed pitching. Lucky for him, and fantasy managers, the Tigers are projected to square off against righties in each game of their upcoming weekend series against the Mariners, and should see at least two in the following series against the Twins. Now healthy, Carpenter is poised to help teams’ home run and RBI numbers.

Ezequiel Tovar, SS, Colorado Rockies

In last week’s article, I featured Troy Johnston, in part because of the Coors Field advantage he would benefit from in the Rockies’ upcoming schedule. We are going back to the well this week, with Rockies shortstop Ezequiel Tovar.

Tovar looked like he was becoming the next big thing at shortstop after a promising 2023 led to a 2024 season in which he hit 26 home runs, racked up 83 runs and 78 RBI, posted a .269 batting average, and had a league-leading 45 doubles. Hip and oblique injuries cut into significant portions of his 2025 season, and this year has started poorly, thanks in large part to his astronomical chase rate.

Last weekend, he reminded us what he was capable of, kicking off a homestand against the Giants with a two-homer game. He has been quiet in Colorado’s visit to the Angels, but the Rockies return to Denver for a back-to-back home series starting this weekend against the Brewers, followed by the Cubs. If Tovar doesn’t have immediate appeal, he is someone to keep tabs on as the Rockies will play at Coors in 19 of their next 28 games.

Owen Caissie, OF, Miami Marlins

Owen Caissie hasn’t done much to capitalize on being handed the Marlins’ right field job after Miami acquired the high-powered prospect in the deal that sent pitcher Edward Cabrera to the Cubs. After slugging 41 home runs and hitting .281 with a .887 OPS over the last two seasons with Triple-A Iowa, hopes were high that Caissie was ready for MLB stardom. So far this season, however, he is hitting .231 with five home runs and thirty RBI.

Lately, Caissie seems to have found his groove. The 23-year-old has lifted his batting average almost 30 points over the last 12 games, going 10-for-31 with two home runs and driving in 11 RBI. In the month of May, Caissie slashed .281/.344/.491, illustrating just how poor his April was. His extraordinary strikeout rate shows no signs of coming down, but his pull and hard-hit rates both showed significant improvement in May as compared to April.

Up next on the schedule for the Marlins are the Tampa Bay Rays. As hot as Caissie has been at the dish, a meeting with the Rays carries the added potential for an extra stolen base or two. The Rays are the third-worst team in the league at preventing stolen bases, having given up 62 to just 14 runners caught.

Roki Sasaki, SP, Los Angeles Dodgers

Roki Sasaki’s MLB career has gotten off to a rocky start, to say the least. One of the hottest pitching prospects out of Japan in the last several years, Sasaki spent most of 2025 injured, and when he was on the field, he performed poorly, giving up six home runs in 36 1/3 innings and logging 28 strikeouts to 22 walks. His playoff performance showed promise of better days to come, but 2026 started much the same way last season did.

In Sasaki’s first seven starts, he averaged less than five innings pitched, allowed nine home runs, and had 31 strikeouts to 16 walks. After that opening stretch, his ERA was at 5.88, and his WHIP was 1.78. Over the next three starts, Sasaki has looked vastly improved. The 24-year-old won two games, struck out 19 (and walked only three!), and allowed four earned runs through 17.1 innings pitched.

This weekend, Sasaki will face the Angels, against whom he enjoyed the best start of his MLB career on May 17, kicking off his recent spate of success. Against the Halos, Sasaki pitched seven innings, striking out eight, and allowing four hits and one run. Looking ahead, Sasaki’s next start after that will likely be against the White Sox, followed by potential matchups against the Orioles and then the Padres, who rank worst and second-worst, respectively, in batting average and wOBA against right-handed pitching this year.

Eric Lauer, SP, Los Angeles Dodgers

Like his new teammate Sasaki, Eric Lauer did not start 2026 on the right foot. Squeezed out of the Blue Jays’ rotation and then used as a bulk reliever, Lauer could never find his groove, and he wasn’t shy about sharing his discontent with his role. Toronto designated Lauer for assignment on May 11 and then traded him to the Dodgers on May 17.

In Lauer’s first start for Los Angeles, on May 26, he secured a win and a quality start, striking out four and giving up one run (another home run) in six full innings. Lauer’s second Dodgers start didn’t go as well, but it was well short of a disaster. In 4 2/3 innings, he gave up five hits and two runs and struck out one. He was removed early after running into a jam in the fifth but would have qualified for another win had he secured the final out.

Lauer won’t pitch again this week but will get a plus matchup when he takes the mound against the Pirates next week. Pittsburgh’s offensive output has been surprisingly good this year, but the team as a whole has struggled against lefties like Lauer. Following that are potential starts against the Rays and Twins, two more teams that have fared worse against southpaws than righties in 2026.

"So far, everything's been comfortable and it's been a very easy transition for me."
