Most Disappointing MLB Teams of the 2026 Season So Far

Most Disappointing MLB Teams of the 2026 Season So Far centers on five clubs whose struggles extend beyond luck. The Houston Astros (33-40) have pitched poorly, posting the third-worst FIP and the second-worst xFIP, though closer Josh Hader returned on June 2 and ace Hunter Brown is slated to return June 16. The New York Mets (32-39) have seen Bo Bichette slump, dropping from the 86th percentile Batting Run Value in 2025 to the 8th percentile in 2026, while Marcus Semien’s defensive value has fallen from the 82nd to the 28th percentile. Luis Robert Jr. has been sidelined since April 30 with a lumbar spine disc herniation, prompting callups of AJ Ewing and Nick Morabito. The Toronto Blue Jays (34-38) have solid pitching but below-average hitting, posting a 96 wRC+ and Vlad Guerrero Jr.’s Batting Run Value staying in the lower percentiles. Louis Varland has emerged as a brighter spot, while the San Francisco Giants (29-43) show a -56 run differential and Rafael Devers carries a 10th percentile Batting Run Value; Logan Webb has delivered some good recent starts. The Texas Rangers (35-36) also rank among the disappointing teams as they seek consistency.
