Taillon pitched two innings and allowed three hits, one run and struck out two batters against the Yankees' Class A team in Pirate City.
Taillon, 19, was the first high school player the Bucs have taken in the first round since nabbing Andrew McCutchen in 2005. The hard-throwing Texan is the seventh high school pitcher the organization has used on its first pick on since 1970.
He has a four-pitch mix with his fastball sitting consistently in the mid- to upper-90s. That fastball touched 99 mph on the radar gun several times. Taillon's curveball and slider have already developed into solid secondary pitches, and the Pirates believe the changeup will come.
Taillon finished his senior year at The Woodlands High School with an 8-1 record, a 1.78 ERA and 114 strikeouts in 62 2/3 innings. The studious Taillon turned down a scholarship offer from national power Rice University and received an $8.5 million bonus from the Pirates.
