Jamie Arnold Shuts Down MLB Pros | Oakland Athletics News

Jamie Arnold, the 11th overall pick in the 2025 Draft, just made his Triple-A debut with the Athletics—just 14 months after being drafted—and dominated in his first start, tossing five scoreless innings against a lineup full of MLB veterans. His breakout season continued in Double-A, where he led all qualified pitchers with a 1.57 ERA in his last four starts and posted a stellar 1.29 ERA over his last five outings. He’s sharpened his changeup since the All-Star break, now using a four-pitch mix against righties and a split-change against lefties, while also throwing first-pitch strikes at an elite rate. What sets him apart? His incredible extension on his fastball (averaging 93 mph) makes his pitches nearly impossible to react to—comparable to top MLB arms. Despite a few walks and hits, he kept runs off the board, even getting a runner thrown out at home in his final inning. Now, he faces the toughest test yet: the Pacific Coast League.
