Tseng impressed scouts when he starred for Taiwan at the 18-and-under World
Championships in the fall of 2012, but his stock fell when his stuff and
delivery took a downturn at the World Baseball Classic the following spring.
The Cubs still signed him for $1,625,000 as part of their 2013 international
binge that also included since-traded stud prospects Gleyber Torres and Eloy
Jimenez. After Tseng made a successful 2014 pro debut in low Class A, his
stuff regressed the next two years before bouncing back in 2017.
Tseng's fastball dropped to the upper 80s in 2015-16 before climbing back to
90-93 mph this season. His fastball lacks life but he compensates by locating
it well to both sides of the plate. He also has regained consistency with his
changeup, his best pitch and a plus offering at its best.
His tight curveball gives Tseng another solid secondary pitch. He's not afraid
to challenge hitters and generally keeps the ball down in the strike zone, a
must for a flyball pitcher with less-than-overpowering stuff. While he doesn't
have a huge ceiling, he's one of Chicago's more advanced rotation prospects and
has a safe floor as a back-of-the-rotation starter.
