Hand-signed on-card 2026 Bowman Chrome Wei-En Lin 1st Autograph Green Lava Refractor, serial-numbered #/99 (Card #CPA-WL), featuring a beautiful Oakland Athletics green color-match border. This is a premier card for one of baseball's fastest-rising young arms; signed out of Taiwan for a massive $1.35 million, the 20-year-old southpaw recently cracked Baseball America’s Top 100 Prospects list and ranks as the Athletics' No. 4 overall prospect. Dubbed by team executives as the "Taiwanese Snellzilla" for his elite five-pitch mix and deceptive Vulcan changeup, Lin has torn through the minors, earning a rapid promotion to Triple-A after dominating Double-A with a microscopic 1.61 ERA.
