Logan Henderson, Milwaukee Brewers
Currently At Triple-A
10% rostered
For potentially the final time on this list, Logan Henderson will hold the top spot. Before their game on Sunday, the right-hander was recalled from Triple-A as Jacob Misiorowski was placed on the 15-day IL with a leg injury. In this start, Henderson went 4 1/3 innings and did not allow a run, and struck out four.
Through his first four career starts in the major leagues, Henderson posted an impressive 1.71 ERA with a 0.95 WHIP. During these four starts, the right-hander struck out 29 hitters and posted a 7.4% walk rate.
He generated a 32.6% HH% and a 33.3% chase rate, which would have placed him near the top of qualified pitchers if he logged enough innings of work.
However, once Brandon Woodruff returned and due to the emergence of rookie breakout Misiorowski, the Brewers opted to send Henderson back to Triple-A, despite his strong start.
Through his first 38 2/3 innings since returning to Nashville, Henderson continued to find high success, posting a 3.49 ERA with a strong 1.11 WHIP. During this stretch, the No. 90-ranked prospect on MLB.com struck out 40 hitters while allowing only nine free passes.
With Misiorowski now on the IL, fantasy managers should expect him to remain in the majors for the foreseeable future. He is a must-target in all formats.
Should we be stashing Logan Henderson on our bench?

Andrew Painter, Philadelphia Phillies
Currently At Triple-A
15% rostered
The Philadelphia right-hander has continued to progress at Triple-A and is on the verge of getting the call to join the major league roster for the stretch run. In his most recent start on July 30, the former first-round pick logged a season-high 6 1/3 innings of one-run ball. He allowed seven hits with just two walks. He struck out four.
In his previous outing, Painter also found success, allowing just two runs across six innings of work with just one hit and a 4:3 K:BB. However, before this recent two-game stretch, the right-hander was in danger of falling out of must-stash territory as he served up a hefty 16 runs and seven walks over his last 24 2/3 innings.
While his overall 4.50 ERA and 1.37 WHIP through 68 innings at Triple-A Lehigh Valley is not overly impressive, seeing him log two-straight games with six innings and quality starts suggests he is putting the final touches on his development. Earlier in the campaign, Painter looked quite strong during his brief rehab start with Low-A as he struck out 12 across 11 1/3 innings of work.
Before undergoing Tommy John surgery in 2023, Painter was a consensus top prospect as he posted an elite 1.56 ERA, 0.89 WHIP, and a 155:25 K:BB through 103 2/3 innings during the 2022 campaign.
Painter has immense strikeout upside and is on the verge of joining a Phillies team that will be playing in important games down the stretch. He is a must-stash in all leagues entering Week 19.

Bubba Chandler, Pittsburgh Pirates
Currently At Triple-A
20% rostered
Sitting comfortably in the No. 3 spot on our list once again is Bubba Chandler of the Pittsburgh Pirates. While Konnor Griffin has surpassed the right-hander in the dynasty lens in the Pittsburgh system, Chandler still remains a top stash option for redraft leagues.
Despite his inconsistencies, Chandler still has a clear path to join the major leagues during the final month of the season.
In his most recent outing, the No. 5-ranked prospect in the sport on MLB.com had another disappointing showing as he allowed a hefty five runs and five hits across 5 1/3 innings of work to the high-powered Iowa Cubs. In this start, Chandler served up a hefty four walks and only struck out two. However, in his previous start, Chandler allowed only two runs in 5 2/3 innings and struck out seven, which shows that when he is pitching at his peak, he can be highly effective.
Through five starts in July, Chandler has allowed five runs in two but has gone on to log 17 2/3 innings of two-run ball during his other three outings.
During his first 48 2/3 innings, Chandler appeared to be knocking on the MLB door; the former third-round pick posted an elite 2.03 ERA, 1.07 WHIP, and a 69:21 K:BB. Even though the Pirates promoted fellow pitching prospect Thomas Harrington before him this weekend, Chandler remains a strong stash option in 12+ team formats as he would carry high-end SP4 upside when he was to be given the call.
What to do with Bubba Chandler? 😡 https://t.co/fLkqB8P8tG

Nolan McLean, New York Mets
Currently At Triple-A
1% rostered
Once again, roughing out the top-5 will be the top budding stars in New York who are on the verge of reaching Queens. Since the Mets did not opt to address their rotation before the deadline, it suggests both McLean and Sproat could have viable paths to join them for the foreseeable future.
McLean opened the season at Double-A but quickly moved up to Triple-A Syracuse after tossing 26 1/3 innings to the tune of a 1.37 ERA and a 1,22 WHIP. During this stretch, he struck out 30 hitters while allowing only 12 walks.
Since moving up to the top ranks of the Mets' system, McLean has shown the ability to find success, suggesting his development is near complete. Through his first 60 2/3 innings at Syracuse, McLean posted an impressive 2.67 ERA and a 1.15 WHIP across 60 2/3 innings. During this stretch, he racked up 65 punchouts.
After allowing a high six runs on July 18, McLean bounced back, tossing 13 1/3 innings over his last two starts with just four earned runs and a stellar 0.75 WHIP. Given the Mets' rotation is currently full, he is only worth stashing in deeper formats for now.
The Mets believe that Nolan McLean and Brandon Sproat can help the team this season if the timing is right https://t.co/11wwRO6ldL pic.twitter.com/RwmdXfo0Bz

Brandon Sproat, New York Mets
Currently At Triple-A
1% rostered
My final pitcher plays alongside McLean at Syracuse. Sproat had a rough start to the season but has quietly been one of the best pitchers at the Triple-A level over the past month. Since June 28, Sproat has logged an incredible 33 innings to the tune of a near-perfect 0.55 ERA with a 0.82 WHIP. He has struck out 39 hitters over this stretch while allowing only 11 walks.
During his first 63 innings of the season, Sproat posted a hefty 6.29 ERA and was not even viewed as a potential call-up candidate at the time.
Similar to McLean above, the Mets have a full rotation at the moment, which will limit Sproat's short-term upside. However, given Clay Holmes' recent struggles, the Mets could opt to shift him to a long relief role, which could open a spot for Sproat. While McLean has had more sustained success this season, Sproat has made the necessary adjustments to turn the corner.
He is worth stashing in deep leagues for the time being. However, if a Mets starting pitcher were to suffer an injury, both McLean and Sproat would emerge as must-stash candidates like Painter and Chandler.
