Sacramento Athletics AA
2026 Fantasy Outlook
Lin doesn't throw very hard, but he reached Double-A at 19 while putting up an excellent statistical debut season. The Taiwanese lefty logged a 3.72 ERA, 1.06 WHIP and a 117:22 K:BB in 87 innings across Single-A, High-A and Double-A. Lin is best known for his potentially plus command/control, as most public scouting services don't grade any of his pitches as plus. His fastball, changeup and curveball all have at least above-average potential, however, so Lin is on track to be at least a No. 4 or No. 5 starter in the majors. If his fastball starts sitting in the mid-90s or his secondary pitches take a step forward, he could be a mid-rotation starter or better. Lin should split the year between Double-A and Triple-A and is well ahead of schedule. Read Past Outlooks

Reaches Double-A at 19
PSacramento Athletics  AA
September 5, 2025
Lin gave up two runs on two hits and two walks while striking out two in 3.1 innings Thursday in his first start for Double-A Midland.
Analysis
The Taiwanese lefty doesn't turn 20 until November, so just the fact he reached Double-A this season is quite the accomplishment. Lin is best known for his potentially plus command/control, as most public scouting services don't grade any of his pitches as plus. His fastball, changeup and curveball all get average or better grades however, so Lin is on track to be a No. 4 or No. 5 starter in the majors. All told, he has a 3.76 ERA, 1.05 WHIP, 111:20 K:BB and 32.7 percent groundball rate in 83.2 innings across Single-A, High-A and Double-A in his first pro season.
