Cleveland right-hander Corey Kluber entered the 2013 season as a 27-year-old with fewer than 70 major-league innings. He’s departing it, however, having established himself as one of the club’s — and perhaps the league’s — most effective starters, having recorded strikeout and walk rates of 23.3% and 5.2%, respectively, and a 74 xFIP- that’s fifth among pitchers with 100-plus innings.
Nor does Kluber’s success appear to be founded upon deception alone. His two-seam fastball sits at 93-95 mph. He has command of a cutter, which he throws around 90 mph, to either side of the plate. His slider has excellent two-plane break.
In summary, Kluber’s career arc is an unusual one: he’s in what’s typically a player’s peak-age season, entered that season with little in the way of major-league experience, is having great success in the majors presently, and appears to have the armspeed/command capable of sustaining that success.
