Kade Anderson, the Mariners' top pitching prospect and the No. 3 overall pick in the 2025 MLB Draft, made an impressive professional debut on Friday, striking out 6 batters in 4 scoreless innings for Double-A Arkansas in a 5-4 loss to Midland. The 22-year-old left-hander allowed 5 hits and a walk but worked out of trouble each time, including a strikeout to leave the bases loaded in the 3rd inning.

Why it matters

Anderson is considered one of the top pitching prospects in baseball, ranked No. 18 overall by MLB Pipeline. His strong debut at the Double-A level is an encouraging sign for the Mariners as they look to develop their next wave of young talent to complement their current MLB roster.

The details

Anderson threw 59 pitches, 43 of them for strikes, and forced 12 swings-and-misses. All 6 of his strikeouts were of the swinging variety. The Mariners elected to keep Anderson off the mound for the remainder of the 2025 season after a heavy workload in his final year at LSU, but he impressed in Spring Training and earned a spot at Double-A to start the 2026 season alongside the organization's No. 3 prospect, right-hander Ryan Sloan.
