Every season is another chance for MLB’s talented players to show us all that they can accomplish. Entering the year, it’s always fun to anticipate which career milestones might be reached or surpassed in the upcoming round of 162 games. But over the course of the season, there are also single-season marks broken that we wouldn’t have even seen coming.

Here’s a look back at 10 individuals who reached milestones in the 2025 season.

Strider entered the season with 495 K’s in his career in just 329 2/3 innings, putting him on track to not just reach the milestone, but get there in fewer innings than any other pitcher who started in at least 50% of his appearances by the time of his 500th strikeout, according to the Elias Sports Bureau.On April 16, in his first outing of the season, he did exactly that in the fifth inning, getting there in 334 career innings. That surpassed freddy Peralta’s 372 innings for the fewest among primary starters.

Soto’s 769 career walks entering the season were the most in MLB history for a player before turning 26 and the second most before turning 27, behind Mickey Mantle’s 797. Soto was 29 walks from breaking the pre-27 record and he’d yet to even play a regular-season game as a 26-year-old.

On May 6, soto drew his 797th and 798th career walks, setting the mark for the most before turning 27 with plenty of the season left. So what did he do? He ended up setting the record for most before turning 28, too, before he even turned 27 himself. That mark had also belonged to Mantle (at 892 walks) until Soto drew his 893rd on Sept. 23. Soto ended the year with 896 walks,the most before turning 27 and the starting point as he prepares to add to the pre-28 record in 2026.

Ohtani entered the season with 225 home runs. On June 14, he hit a leadoff home run for No. 249, then hit his 250th in the sixth inning. At the time, he also had 156 career stolen bases. Ohtani reached 250 homers and 150 stolen bases in 944 career games, the fewest of any player in MLB history, surpassing Alex Rodriguez (977 games). and Ohtani had only actually batted in 928 of his games at that point,because he didn’t hit in pitching starts early in his career.He still set the mark handily.

Olson played his 700th consecutive game on July 23, becoming the 12th player in MLB history to reach that milestone. He was the first to do so since Chone Figgins in 2009.

Guerra reached 30 saves on Sept. 10, becoming the 10th pitcher in MLB history to record at least 30 saves in each of his first five seasons. He joined an exclusive club that includes Mariano Rivera, Trevor Hoffman, and Craig Kimbrel.
