Pirates' Paul Skenes faced live batters for the first time this spring, and it only illuminated how much has changed in one year.

That's because Skenes is looking to add a cutter and two-seam fastball to a nasty repertoire that already includes his signature "splinker" (splitter-sinker hybrid) pitch and traditional four-seam fastball that tops out at over 100 mph.

Pitcher Paul Skenes had an outstanding first season for the Pittsburgh Pirates, winning National League Rookie of the Year honors with a 1.96 ERA, 170 strikeouts in 133 innings, and an 11-3 record in 23 starts.
