The St. Louis Cardinals have a star on their hands in rookie second baseman JJ Wetherholt and the front office clearly knows it. Early in the campaign, there were rumors out there about the possibility of the Cardinals signing Wetherholt to an extension. The noise picked up steam as other young guys across the league, like Konnor Griffin, Cooper Pratt, Luis Lara, and Kevin McGonigle, among others, started getting extensions left and right. On Friday, it was finally Wetherholt's turn. ESPN's Jeff Passan reported that the Cardinals and the 23-year-old infielder are in agreement on a long-term deal that will buy out "multiple" years of free agency and is in the range of nine-figures.

Wetherholt has played in 87 games so far this season as a rookie and has looked like a 10-year veteran. From Opening Day when he launched his first career big league homer to now, he has just been incredible. — MLB (@MLB) March 26, 2026So far this season, Wetherholt is slashing .267/.362/.411 with a .773 OPS, 13 homers, 36 RBIs, nine stolen bases, 38 walks, 10 doubles, and 57 runs scored. He has only struck out 61 times as well this season in 87 games, which is massively important at the top of the order. He gets on base and sets the tone. He was snubbed from the All-Star Game, to say the least. His time will come. On top of this, he has been among the best overall defensive players in baseball this season. Right now, he has racked up 16 outs above average. That's ridiculous and has him at the top of the MLB leaderboard with the likes of guys, including Bobby Witt Jr., Pete Crow-Armstrong, and Ceddanne Rafaela, among others. Also, Wetherholt is tied for 12th in all of baseball with 3.9 wins above replacement. Again, this is a rookie we're talking about who is just 23 years old. He is just going to get better and he will be donning a Cardinals uniform for a very long time. Add us as a preferred source on GoogleFollow
