MLB’s rookie class is making a powerful affect in early season video games

PHOENIX (AP) — Pittsburgh Pirates phenom Konnor Griffin stepped to the plate on Tuesday night time in opposition to the Arizona Diamondbacks and ripped a 110.1 mph laser excessive off the center-field wall at Chase Field, cruising into second base for a double.

D-backs supervisor Torey Lovullo’s jaw dropped virtually to the dugout flooring.

“Twenty years old and driving the ball off the center field wall,” Lovullo stated. “Let’s go back to being 20 years old. I was just getting hair under my armpits, and this guy’s in a big-league baseball game. It’s impressive.”

Griffin — who simply turned 20 a number of weeks in the past — is a part of an MLB rookie class that’s made an on the spot affect because the calendar turns to May. He’s batting .256 with two homers, 16 RBIs and is 8 for 8 on stolen bases, all whereas enjoying shortstop at a excessive degree for a Pirates crew that has a 21-17 file.

Even the 2025 class, which wasn’t as deep, featured examples of gamers able to make an unusually quick affect. Nick Kurtz bought simply 210 at-bats within the minor leagues earlier than becoming a member of the Athletics, then batted .290 with 36 homers and 86 RBIs over 117 video games to win American League Rookie of the Year in 2025.

“Everything is fast-forwarded now, everything’s on speed dial, everything happens really quick,” Lovullo stated. “These kids are developing. It’s the same message I send to our group about player development. We aren’t going to be the L.A. Dodgers or the Padres. Spots won’t be filled by Player ‘X’ coming off of free agency. Spots will be filled by someone in this clubhouse.”
