As Major League Baseball enters its final week of the regular season, 13 teams remain in contention for postseason play, yet none present a fully balanced roster without significant vulnerabilities. These weaknesses could prove decisive as October approaches, a month when flaws can be exploited under playoff pressure.
The Milwaukee Brewers, boasting the best overall record at 98-58, face a question mark beyond their ace, Jacob Misiorowski. While Misiorowski and Logan Henderson have anchored a strong rotation, injuries and inconsistent performances have left the Brewers thin behind them. Key starters Brandon Woodruff and Quinn Priester underwent season-ending surgeries, and Kyle Harrison’s form has sharply declined since midseason. The Brewers have the talent to lead the majors but may struggle to sustain it deep into the postseason.
In the American League, the Tampa Bay Rays head the AL East at 95-60 and are close to clinching home-field advantage through the American League Championship Series. However, their lineup’s bottom third ranks 24th in major league OPS, with players like Taylor Walls and Jorge Mateo contributing limited offensive production. This lack of depth was a factor in their swift 2023 playoff exit, when a run-scoring drought at the bottom of the order coincided with an early elimination.
The New York Yankees, despite leading MLB with a 3.08 bullpen ERA, rely heavily on just three relievers—closer David Bednar and setup men Brent Headrick and Paul Blackburn—trusted in high-leverage moments. The bullpen’s depth has been compromised by the midseason trade of Camilo Doval and the injury to Fernando Cruz. Headrick and Blackburn had logged unusually high innings by late September. Historical precedent warns of such overuse; the 2016 Cleveland bullpen’s exhaustion cost the Indians a World Series title after a Game 7 loss.
Similarly, the Boston Red Sox’s bullpen depth is under scrutiny. After securing a playoff spot at 84-72, their relief corps has been depleted by injuries to Justin Slaten, Tyron Guerrero, and lat tightness for closer Aroldis Chapman, who has 34 saves and a 1.95 ERA. Garrett Whitlock has been deployed in unfamiliar save situations due to these strains, exposing Boston’s limited bullpen reserves.
The Chicago White Sox’s pitching challenges also threaten their playoff prospects. Their starting rotation has struggled to reach the sixth inning consistently, forcing heavy bullpen use. Key arms like Luis Castillo were shifted to relief roles after faltering as starters, and others have been pulled early in games, contributing to their recent loss of first place in the AL Central.
Cleveland’s postseason outlook is clouded by the absence of reliable setup men Emmanuel Clase and Luis Ortiz, both on unpaid leave amid ongoing federal trials concerning pitch-rigging allegations. Closer Cade Smith carries the bullpen, which has been further undermined by recurring injuries, leaving inexperienced pitchers to handle crucial innings in October.
The Houston Astros and Texas Rangers are locked in a tight AL West race, but both face bullpen instability. Houston has lost its top setup relievers to injuries, leaving a high ERA reliever and one who recently blew a save as their primary bridges to closer Josh Hader. Texas has lost two relievers for the season and turned starters Nathan Eovaldi and Jordan Montgomery into emergency bullpen arms, an arrangement rarely sustainable in October.
The Atlanta Braves’ rotation has been decimated by surgeries to Spencer Schwellenbach, Hurston Waldrep, and Bryce Elder, with only Chris Sale and Tyler Mahle regarded as reliable postseason starters. This echoes the Braves’ injury challenges in 2013, which coincided with an early playoff exit.
In the National League, the Philadelphia Phillies rely on recent acquisition Jhoan Duran to stabilize their bullpen but face questions over the health and consistency of setup men Orion Kerkering and Jonathan Bowlan. The young arms left to cover the highest-leverage innings have limited major league experience heading into the playoffs.
The Chicago Cubs present a potent offense, ranking first in MLB runs scored, but their pitching staff has conceded the most home runs in the league. Injuries and inconsistent performances by key pitchers, including Kevin Gausman and Clay Holmes, have added concern about their ability to contain opponents in October.
The Los Angeles Dodgers clinched their fifth consecutive NL West title but continue to grapple with a beleaguered bullpen. Reliever Edwin Diaz struggled before and after returning from injury, with Tanner Scott also inconsistent. Setup man Edgardo Henriquez is sidelined with a back strain, limiting the Dodgers’ options in late innings.
The San Diego Padres, battling for a wild-card spot, have been hampered by injuries to Luis Rengifo and others, forcing reliance on September call-ups to fill roster spots. With limited bench depth and a thin portion of the season remaining, their capacity to sustain a playoff push remains uncertain.
Among contenders, a recurring theme emerges: while many boast potent offenses or strong starting rotations, the depth and durability of their bullpens and back-end pitching staffs are fraught with risk. These pitching and lineup deficiencies could be pivotal in deciding which teams advance and which see their seasons end prematurely as MLB moves toward the postseason.
