Carlos Perez, 23, AAA. 1.7 WAR .259/.323/.385 with 6 HRs and 3 SB's.
Perez joins the Halos following a decent if unremarkable campaign in Oklahoma City, the Astros' PCL affiliate. Even there he spent most of the year as backup, playing caddy to their Max Stassi, so his total WAR contributions reflect the limited playing time. Strengths with the bat include a knack for contact and decent walk rate. If anything, he may have been a bit unlucky last year with the .295 BABIP, and that number could jump big time in the friendly Salt Lake environment. Perez pulls a lot of pitches in the air, but scouts presently don't think there's MLB-caliber juice there. At just 23, he may grow into a little more, and even a marginal bump could make him starter. Once regarded as a bat-first prospect, his perceived value is now entirely tied to his glove. Caught stealing rates and scouting reports support those projections.
He threw the ball extremely well with the Burlington Bees, then less well with two High A affiliates. He possesses three major league pitches in his 90-93 mph fastball, change-up and slider, and each offering can look fantastic at times. He has a fringy curveball too, which he uses primarily as a show-me pitch early in the count. The deuce improved significantly since before 2012 Tommy John surgery, so hell, he may wind up with even four big league weapons. His numbers nonetheless say that he was overmatched in High A, especially against lefties: they walked often, hit too many linedrives, too few pop ups, and consistently squared the ball hard up the middle of the field. Clevinger induced a 50% GB rate against those opposite-handed hitters, which may prove a strength yet, but too many of those grounders wound up in centerfield for it to have mattered in 2014. He remains a sleeper, but the breakout has yet to happen.
