Chase Burns, Cincinnati Reds

Currently At Double-A
15% rostered

We have a new No. 1! After a few weeks of sitting just below Bubba Chandler, Chase Burns will finally take the top spot. The former second overall pick has yet to slow down since making his professional debut earlier this season. The Wake Forest product opened the campaign with High-A and needed just 11 2/3 innings to prove he was ready to join Double-A.

During this stint, Burns allowed just four runs and struck out 20 batters.

Then with Double-A, Burns continued to impress, logging 42 innings to the tune of a stellar 1.29 ERA and a 0.7 WHIP.

During this stretch, Burns held a near-perfect 55:4 K:BB and allowed just three total home runs. This incredible production earned him a quick promotion to Triple-A.

Chase Burns needs to be treated as the No. 1 prospect going forward

While Burns looked a slight step back (to his standards) in his Triple-A debut, allowing two runs across 5 1/3 innings to the potent Iowa Cubs, Burns responded in a big way in his second game with Triple-A Louisville. In this second outing against Scranton/Wilkes-Barre, Burns tossed seven innings of one-run ball with three hits, no walks, and seven strikeouts.

Given the current state of the Reds rotation with Hunter Greene (gorin) on the 15-day IL and No. 5 starter Wade Miley (forearm) also on the IL, Burns will provide a much-needed spark.

On Saturday evening, the Reds announced that they will be promoting Burns to make his MLB debut on Tuesday evening against the New York Yankees. Burns is a must-add and must-start pitcher going forward.

We guarantee that Chase Burns outperforms at least one—if not several—starting pitchers on every major league roster.

Bubba Chandler, Pittsburgh Pirates

Currently At Triple-A
30% rostered

Even though Chandler moved down to the second spot on the list, he should still be viewed as a must-stash. Chandler was in a bit of a slump through early June at Triple-A Indianapolis. During his two starts on June 5 and June 11, the No. 2-ranked prospect in the sport on MLB.com logged just 2 2/3 innings with four earned runs, five walks, and one strikeout.

Despite this poor stretch, Chandler bounced back in a big way on June 17, tossing four innings of one-run ball with five hits, one walk, and three strikeouts. While this outing was not elite, it was a great sign given his struggles, especially regarding his command.

However, the right-hander took another step back on Sunday as he allowed six runs and five hits across just 2 2/3 innings of work.

During his first 48 2/3 innings of the season before Sunday's meltdown, Chandler has served up a rather high 21 walks but has struck out 69 hitters while holding a 2.03 ERA and a stellar 1.07 WHIP. While he has struck out at least eight batters in four starts, he has also allowed four or more walks in three.

Chandler made his Triple-A debut last season and enjoyed similar success, posting a 1.83 ERA and a 1.04 WHIP across 39 1/3 innings of work. During this first taste, he allowed just 15 walks and struck out 54 batters.

Even though his command has been shaky at times, the 22-year-old has continued to flash immense strikeout upside and remains a solid stash candidate heading into Week 13.

Andrew Painter, Philadelphia Phillies

Currently At Triple-A
5% rostered

Unlike the first two players on this list, Painter has a longer path ahead of him until he reaches the majors. Earlier this month, Phillies manager Rob Thomson noted that Painter will likely make his MLB debut in the second half of the season. However, given his current progress at Triple-A, the top prospect in Philadelphia could be headed to the majors right after the All-Star break.

Painter is coming off a strong outing on June 15, where he tossed five one-hit innings (no runs) with one walk and six punchouts against Triple-A Worcester. Then, on June 21, Painter continued to produce, tossing five innings of two-run ball with five punchouts.

Before this stretch, Painter allowed a combined 14 hits and 10 runs over his last two starts (nine innings).

Since joining Triple-A Lehigh Valley, the former 13th overall pick has struggled at times as he sits with a modest 4.35 ERA and a 1.35 WHIP. However, Painter's primary concern was his pitch count after missing all of 2023 and 2024, recovering from Tommy John and numerous setbacks.

Painter began the season with Low-A Clearwater, where he logged 11 1/3 innings to the tune of a 3.97 ERA, 0.97 WHIP, and a 12:1 K:BB.

While Painter is not a "must-stash" like the two names above him, he needs to be stashed in all 12+ team leagues. His debut can come quite early in the second half, especially if he can build on his latest start.

Hard to believe the Phillies won’t have the best rotation in baseball once Andrew Painter arrives in Philadelphia!

Quinn Mathews, St. Louis Cardinals

Currently At Triple-A
1% rostered

After missing most of the season with left shoulder inflammation, the top pitching prospect in St. Louis is back in action and once again knocking on the MLB door. In his most recent outing on June 18, Mathews allowed just one hit across five shutout frames against the Norfolk Tides. In this start, the left-hander struck out six batters and allowed two walks.

Through 26 Triple-A appearances this season, the left-hander has posted a solid 3.86 ERA and 1.73 WHIP. However, many of his ratios are inflated due to his rough start, which was likely due to his injury.

Over his last 13 innings (three starts), Mathews has allowed just two runs, six walks, seven hits, and has struck out 17 batters.

This is an excellent sign as the Stanford product struggled during his first taste of Triple-A last season, posting a hefty 6.48 ERA and a 1.93 WHIP across 16 2/3 innings of work. However, his time with Low-A, High-A, and Double-A was quite impressive, as Mathews posted a 2.27 ERA and a 0.85 WHIP through 126 2/3 innings of work.

While a debut may not be imminent, he should remain in play to make a second-half MLB debut.

LHP Quinn Mathews (AAA) was nearly unhittable this afternoon, tossing 5.0 scoreless innings while allowing one base hit (single) and punching out 6.

Joe Boyle, Tampa Bay Rays

Currently At Triple-A
1% rostered

While Boyle has already had a stint in the majors last season, pitching to a hefty 6.42 ERA and a 1.72 WHIP across 47 2/3 innings with the Athletics, I still consider him a "prospect" given that this was his longest stint in the bigs.

Boyle was given a spot start with Tampa Bay this season and looked like an entirely different pitcher, tossing five innings of two-run ball (no earned runs) with no hits, two walks, and even punchouts against the Braves.

Boyle has looked just as dominant in Triple-A and is making a strong case to stay in the Tampa Bay rotation in the long term. Through 64 innings with Triple-A Durham, the right-hander has held a 1.83 ERA and a 0.95 WHIP. During this stint, Boyle has struck out 81 batters and allowed just 25 free passes.

Over his last four outings, Boyle has struck out at least eight batters in each outing and allowed just four total earned runs (across 21 innings).

While the Tampa Bay rotation does not have a clear spot for Boyle, his success may push its hand. If the Rays remain in the Wild Card race, they may also opt to deploy a six-man rotation to preserve innings.

In either outcome, Boyle will carry high strikeout upside when he returns to the majors and is worth stashing in all 12+ team leagues for the time being.

Joe Boyle had his 4th straight outing of 8+ K on Thursday for Triple-A Durham.

My concern with Boyle was always the control, but that has improved lately.
