Wei-En Lin Fantasy Stats

Athletics pitching prospect Wei-En Lin recently moved up to Triple-A and is positioning himself to compete for a second-half debut. While Gage Jump, the team's higher-ranked pitcher, earned the call earlier this season, Lin is waiting in the wings and could find himself high on the star radar in the coming weeks. Lin opened the 2026 regular season with Double-A Midland, where he was near-perfect, holding a 1.93 ERA with a stellar 0.84 WHIP. Over this 51 1/3-inning stint, Lin struck out 53 hitters while walking just 13. This strong start earned him a ticket to Triple-A, where he has encountered some growing pains. Over two outings (1 2/3 innings), Lin has allowed eight earned runs with a 1:4 K:BB. While it will take the No. 90-ranked prospect in baseball some time to adjust to the Triple-A hitters, he could climb the stash ranking in the second half, making him a top prospect to monitor in deeper leagues.

The Athletics are promoting left-handed pitching prospect Wei-En Lin from Double-A Midland to Triple-A Las Vegas on Friday, according to Milb Central. The 20-year-old native of Taiwan earned the promotion to the Aviators after going 3-1 with a sharp 1.93 ERA and 0.84 WHIP with 53 strikeouts and 13 walks in 51 1/3 innings pitched across his 10 starts. The 6-foot-2, 179-pound southpaw is ranked as the A's No. 4 prospect, per MLB Pipeline, and could be in line to make his major-league debut in the second half of the 2026 season if he continues to impress this summer in Sin City. Lin typically sits in the mid-90s with his fastball and has a diverse pitch mix that also features a slider, curveball, changeup, and splitter, all of which have the potential to be plus offerings. His greatest strength is his ability to throw strikes, which could earn him a ticket to Sacramento sooner rather than later. Lin doesn't have high-end fantasy upside, but he should at least become a backend starter for the A's once he reaches the big leagues.
