Scouting Report

2025

Scouting grades: Fastball: 50 | Slider: 45 | Changeup: 55 | Control: 55 | Overall: 40

While most of the buzz around an international signing period centers around when it opens in January, that doesn’t mean teams stop scouting and signing players from around the globe. Case in point is Shen, who signed with the Mariners for $175,000 last July as part of the 2024 signing class. The 21-year-old Taiwanese right-hander officially embarked on his pro career stateside this May in the Arizona Complex League.

A 6-foot-3 hurler with a starter profile, Shen has a solid frame and displays excellent athleticism on the mound. The stuff may not wow anyone, but his feel for pitching might. He’ll typically sit around 92 mph with his fastball and can touch 95. He has an above-average changeup he sells well with good deception. He has feel for spinning a slider, but there’s not quite enough power or bite on the breaker just yet.

All of Shen’s stuff does play up because he can throw all three offerings for strikes and knows how to miss bats by mixing his repertoire well and keeping hitters off-balance. His ceiling might be a bit limited, but his pitchability could help him move a bit more quickly and become a back-end starter in the big leagues.
