As September rolls around, several MLB stars are on the brink of solidifying their legacy with a strong finish to the season. Players like Jacob Misiorowski, Pete Crow-Armstrong, and Yordan Alvarez are poised to collect major awards in November, but a cohort of other athletes is also fighting for their reputations as the postseason approaches. With the final month of the 2026 MLB season underway, let’s dive into ten players with the most to prove before October hits.

Ketel Marte Faces Pressure in Arizona

The Arizona Diamondbacks are thrilled to have former NLCS MVP Ketel Marte back in their lineup. After a multi-week absence due to being placed on the restricted list for not appearing at a game in Boston on August 17, his return is eagerly awaited. Currently, Marte, a three-time All-Star, has hit 21 home runs this season. However, his on-base plus slugging percentage (OPS) sits at .760, significantly lower than the .887 he posted from 2023 to 2025.

As the Diamondbacks battle to secure the final wild-card spot against the San Diego Padres, Marte’s performance is crucial. Despite his diminished trade value and potential concerns about a future with the team past 2026—thanks to his 10-and-5 rights allowing him to control trades—he needs to prove he remains an elite player.

Aaron Judge's Road to Recovery

Aaron Judge, a three-time AL MVP, has faced a challenging season, sidelined since late May due to a fracture in his right ribcage. Encouragingly, Yankees manager Aaron Boone stated, "I think it's possible" for Judge to return during next week’s homestand. With a .907 OPS in 59 games prior to his injury, Judge's comeback is crucial for the Yankees, positioning them as favorites in a surprisingly weak AL.

Zack Wheeler Needs to Regain Form

For Philadelphia Phillies pitcher Zack Wheeler, the season has been a tale of highs and lows. After a remarkable recovery from a blood clot and thoracic surgery, he initially thrived with a 10-1 record and a 2.13 ERA over his first 15 starts. However, he has faced difficulties since being snubbed for the All-Star game, posting a 1-4 record and a 6.27 ERA in his last eight outings.

Wheeler's recent improvement, limiting the Los Angeles Angels to just one earned run in six innings, is promising. Still, with offseason success expected from pitchers Cristopher Sánchez and Jesús Luzardo, they will need Wheeler at his best for a successful postseason.

Roman Anthony's Opportunity to Shine

Under interim manager Chad Tracy, the Boston Red Sox have experienced a surprising turnaround largely without rookie sensation Roman Anthony. After recovering from a right wrist sprain that held him back for nearly four months, Anthony has returned to the field. In his debut season, he showcased promise with a 2.8 WAR in just 71 games, but injuries have hindered his progress.

With his previous season ending prematurely due to a left oblique strain, Anthony must prove he can stay healthy and contribute consistently if the Red Sox aim for postseason success.

Shohei Ohtani's Uncertain Return

Shohei Ohtani has been a dual threat this season, excelling as both a hitter and a pitcher. However, uncertainty looms over his ability to return to the mound after facing setbacks last weekend. If unable to pitch, the Dodgers can still rely on him as a designated hitter, but his health remains critical for their playoff aspirations. He is currently having one of his best seasons on the mound, with an 8-2 record and a remarkable 1.79 ERA. Still, the team will need clarity on his knee's impact on his hitting as they target repeat success in October.

Cal Raleigh's Bid for Redemption

After an explosive 60-homer season, Cal Raleigh has struggled to replicate that success in 2026. Despite a disappointing .195 batting average in August, he managed to contribute nine home runs, including a notable three-homer game against the Phillies. His ability to rally the Seattle Mariners and lead them into the postseason can turn around what has been a lackluster follow-up season.

Ronald Acuña Jr. and the Braves' Push

The 2026 season has not unfolded as expected for Ronald Acuña Jr., once hailed as the most explosive player in baseball. Returning from a torn left ACL, Acuña's 2026 stats show a .241 batting average and just 13 home runs, leading to questions about his consistency. Still, with the Braves maintaining a lead in the NL East, if Acuña can regain his form, they could be formidable contenders in the postseason.

Trea Turner’s Struggles

Last season's NL batting champion, Trea Turner, has faced a challenging year with a batting average of .241 and an alarming number of defensive errors. For the Philadelphia Phillies to move forward in October, Turner must regain his confidence at the plate and return to the electric offensive player he's capable of being.

Brandon Woodruff's Health Update

Brewers’ pitcher Brandon Woodruff faces a race against time to return to form as he deals with a recurring shoulder injury. Having undergone surgery more than a year ago, he boasts a 3.11 ERA but has made only 21 starts. Manager Pat Murphy's cautious optimism about Woodruff’s potential return could provide a significant boost to Milwaukee’s World Series hopes.

Can Manny Machado Turn It Around?

For the Padres, Manny Machado has had a season rife with challenges despite hitting 24 home runs, as he's batting a troubling .220. With rising stars like Fernando Tatis Jr. and Jackson Merrill performing spectacularly, Machado must elevate his game to secure the Padres a chance at a postseason berth.

As the clock ticks down on the regular season, these ten players face the pressure of proving their worth in these crucial moments, shaping not just their careers but the futures of their teams as they head into October.
