3 Impact Fantasy Baseball Prospects To Stash - Bubba Chandler, Logan Henderson, Joe Boyle

June 25, 2025

Three top fantasy baseball prospects - Bubba Chandler, Logan Henderson, Joe Boyle - that can make big impacts. These MLB prospects are waiver wire pickups or stashes.

Throughout the early part of the campaign, fantasy managers have seen several prospects earn the call to the major leagues and make an immediate impact.

In this piece, we will look at three of the top pitching prospects in the sport and determine if they are worth stashing in standard leagues in Week 13 of the fantasy baseball season.

Should those players be left on the waiver wire, or should fantasy managers add them before their breakout? Let's dive in!

Bubba Chandler, SP, Pittsburgh Pirates

Current Level: AAA
Availability: 5% rostered
2025 AAA stats: 58 IP, 3.41 ERA, 1.28 WHIP, 74 SO, 29 BB

Even though Chandler has struggled recently, 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 prior to 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.

Logan Henderson, SP, Milwaukee Brewers

Current Level: AAA
Availability: 5% rostered
2025 MLB stats: 21 IP, 1.71 ERA, 0.95 WHIP, 29 SO, 6 BB

The Milwaukee Brewers needed some rotation help at the beginning of the season. They had three different pitchers on the injured list (Brandon Woodruff, Nestor Cortes, and Aaron Civale) and needed someone to fill innings until the rotation got healthier. That's when the Brewers decided to call up their No. 12 prospect in the middle of April. 

Logan Henderson made a spot start on April 20 before being sent back down following that outing. However, he was called upon once again a few weeks later. Even after looking strong in three straight starts in his second major league stint, the Brewers demoted him to Triple-A on May 26. 

Henderson made a strong first impression in the big leagues in that spot start on April 20. He threw six innings of one-run ball with nine strikeouts against the Athletics. Although he was optioned to Triple-A the next day, he got another opportunity when Jose Quintana landed on the 15-day IL in the middle of May. 

Henderson essentially replaced Quintana in Milwaukee's rotation and continued to show his potential on the mound. He allowed just three earned runs across 15 innings in his next three outings from May 14 to May 25, including five shutout innings with seven strikeouts against the Baltimore Orioles in his third career start.

Despite those results, the Brewers made the tough decision to send Henderson back down. Quintana was set to return in the coming days, and there just wasn't anywhere for the rookie to fit in the rotation. This was definitely not an easy choice for Milwaukee, considering the right-hander had a 1.71 ERA and 29 strikeouts across his first 21 innings. 

Since being optioned on May 26, Henderson has not gotten another shot in the majors. He remains with Triple-A Nashville and has allowed one earned run or fewer in three of his four starts since returning to the minors. It might also be some time until we see the 23-year-old back with the major league club. 

The Brewers' rotation has been one of the best in the league this season. Freddy Peralta has a 2.76 ERA, Chad Patrick has allowed two runs or fewer in five of his last eight starts, Quinn Priester has a 2.29 ERA since May 13, Quintana continues to do his best to keep Milwaukee in games, and top pitching prospect Jacob Misiorowski could be here to stay. 

Therefore, it could be weeks until we see Henderson back in the big leagues. That makes the right-hander only a stash in deeper leagues right now. There are a few better pitching prospects to stash at this point in the season, including the two other names in this piece.

Joe Boyle, SP, Tampa Bay Rays

Current Level: AAA
Availability: 5% rostered
2025 AAA stats: 64 IP,  1.83 ERA, 0.95 WHIP, 81 SO, 25 BB

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 really 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 their hand. If they 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.

Last 11 GS: 56 IP, 1.77 ERA, 0.89 WHIP, 8.8% BB, 32.9% K, .159 BAA#RaysUppic.twitter.com/LqId8VsKO3
