The outlook on Wily Peralta hasn’t drastically changed over the last year. Coming into 2014, he was a young arm in possession of some tantalizing skills: elite velocity, two plus pitches, and a tremendous groundball rate. He repeated all of that in 2014 en route to his best season yet, but there are still some issues to iron out. His season essentially breaks up into three parts, with his success against left-handers setting the tone in each.
He got off to a great start with a 2.12 ERA in his first 10 starts. The wheels came off for an eight-start run in early-summer, and he was tattooed for a 6.38 ERA before closing out the season with a 3.00 ERA in his last 14 starts, as he held the opposition to 29 earned runs – 13 of which came in two ugly starts at the end of August. His OPS against lefties in the three parts were .681, 1.063, and .759. The blowup in the middle was fueled by the slider getting uncharacteristically smashed for a couple of weeks, as all five homers that lefties hit off the pitch came during that stretch. He allowed a 1.420 OPS with the pitch, despite a 10-to-1 strikeout-to-walk ratio in the 24 plate appearances. Small samples can really hurt!
