Jj Wetherholt’s first season in the majors has hit a rough patch at the exact moment the Cardinals need him to keep producing. After opening 2026 with his first hit and first home run, Wetherholt went into May with numbers that still looked strong. Through April, he was hitting.256 with an.856 OPS and seven home runs. Since the calendar turned, though, the bat has quieted. In May, he is hitting.182 with a.540 OPS and has only one extra-base hit.
That slide has shown up over a longer stretch too. Wetherholt is 10 for his last 55, a reminder that the early-season burst has given way to the realities of a first full 162-game grind. For a player seeing his first taste of the major leagues in 2026, the adjustment has been less about the stage and more about the pitches that keep beating him.
Breaking balls and off-speed pitches have been his problem for a while, both in the minors and now in the majors. This season, Wetherholt is hitting.178 against breaking balls and.212 against soft stuff. Those numbers help explain why pitchers have been able to slow him down after his strong April, and why the current skid has been more than a short-term cold spell.
The timing matters because the Cardinals are about to be tested by familiar opposition. Their next four series will come against all four National League Central opponents, giving division rivals a direct look at Wetherholt’s early strengths and the weaknesses they can try to exploit. For a rookie still learning how major league pitchers will attack him over a long season, that is not a soft landing.
What happens next will say a lot about how quickly Wetherholt adjusts. He has already shown he can drive the ball and put together a productive month. Now he has to answer the same question every young hitter eventually faces: whether he can make the leap once pitchers stop giving him the fastball version of the game.
