Also off to a sluggish start are the reigning AL champion Toronto Blue Jays, who aren’t in last place but do have a -22 run differential.
The division races are subject to some volatility, given that we’re not quite two weeks into the regular-season schedule. The sample is small. But, as the saying goes: Just because you’re paranoid, it doesn’t mean they’re not out to get you. Some of these slacking teams have real reason to worry their disappointing starts have staying power.
Feelin’ Blue Jays
The Jays not only own the ugly run differential, but they already have some serious injuries to overcome. Even before Opening Day, right-handers José BerrÃos, Shane Bieber and Trey Yesavage were absent from the starting rotation. Yesavage is working his way back with optimism, but the other two bring lingering doubts. The Jays also lost Cody Ponce to knee surgery because of a sprained ACL.
Also: Catcher Alejandro Kirk broke his left thumb on a foul tip. Outfielder Addison Barger sprained his ankle. Great gosh almighty, it’s not even mid-April.
No, Cubs, No

The Cubs have some serious pitching woes. Three-fifths of the starting rotation is on the shelf, though left-hander Justin Steele has started to face live hitters in his return from elbow surgery. Less-happy news includes recent injuries to left-hander Matthew Boyd (biceps strain) and season-ending UCL surgery for right-hander Cade Horton.
Tigers stuck in cage
The Tigers don’t have a lot of obvious reasons for concern, but their slump and collapse in 2025 wasn’t 100% logical either. This group can just get out of whack for a couple of weeks at a time. Overall, they haven’t played that badly so far, and come in with a -1 run differential. They’ve also only played three home games. The WBC business might have knocked Tarik Skubal off his ideal prep schedule.
Something to keep in mind for the long haul: Injuries have picked away at the Tigers pitching depth, with Justin Verlander joining Reese Olson and Troy Melton on the injured list.
Sawx need a good warshing
Boston Red Sox pitcher Connelly Early (71) throws a pitch in the second inning of the MLB Interleague game between the Cincinnati Reds and the Boston Red Sox at Great American Ball Park in downtown Cincinnati on Sunday, March 29, 2026. The game was scoreless after three innings. They’re not scoring a lot of runs, they’re not hitting a lot of home runs (as many projected). Aroldis Chapman’s velocity is down (he is 38 years old, after all), and the bullpen depth looks shaky for either performance or injury reasons. The Red Sox looked like an oddly constructed team during Spring Training and now they have a disappointing record to reflect it.
Don’t get rattled, Seattle
The Mariners have the worst record and the fewest actual concerns of any of these teams.
Cal Raleigh, Josh Naylor and Julio RodrÃgez are all slumping, but it won’t last. They’re 1-5 in one-run games, a stat that’s sure to improve. They’re sixth in starting pitcher ERA, which is the expected strength of the team anyway. They’re also playing better defense than they did in ’25. They’re about to rattle off 20 wins in 28 games, or something.
