In the dog days of a long season, when the grind starts to expose every flaw, a second baseman from West Virginia is doing things that make even the most jaded Cardinals fans sit up straight. JJ Wetherholt isn’t just holding his own in the big leagues — he’s threatening to crash the record books in his very first full year.
Through 48 games, the 24-year-old is slashing .239/.357/.413. On the surface that batting average looks modest, but dig deeper and the numbers get ridiculous. He’s currently on pace for 30 home runs, 79 RBI, 115 runs scored, and 20 stolen bases. That’s not just a solid rookie campaign. That’s historic territory.
If Wetherholt maintains this pace, he’ll become just the 18th rookie in MLB history to post a 20/20 season — and only the third ever to deliver a 30/20 rookie year, joining elite names like Nomar Garciaparra, Chris Young, and Mike Trout. For a player many scouts once viewed primarily as a high-contact, doubles machine with sneaky pop, this kind of power-speed combination has been a revelation.
Those who followed his prospect journey knew the ingredients were there: elite plate discipline, plus speed on the bases, and more thump than the consensus gave him credit for. But even the biggest believers probably didn’t circle a 30/20 rookie season on their bingo cards. Wetherholt has blown past best-case scenarios and is forcing everyone to recalibrate.

Yet here’s the scariest part for opposing pitchers: he’s still not at his peak.
His .770 OPS already delivers impact, but those who’ve watched him since college know the real JJ Wetherholt sprays line drives to all fields with authority. Right now he’s walking at an excellent clip and punishing mistakes, but the consistent hard contact to every part of the park hasn’t fully arrived. With only five doubles so far, there’s clearly more in the tank. Lately, though, he’s shown signs of unlocking that next gear, driving the ball the other way with more frequency.
Add in his smooth defense up the middle — already drawing praise from the coaching staff — and you’ve got a complete player emerging at second base for the Redbirds. In a loaded National League Rookie of the Year race, Wetherholt is making his case impossible to ignore.
This isn’t just another prospect flashing potential. This is a young Cardinal building something special in real time, one disciplined at-bat and extra-base hit at a time. Busch Stadium has seen its share of legends, but few have arrived with this kind of electricity so early.
