Beresford was the closer at UNLV as a fifth year senior. The reason he’s so old (the oldest the Yankees drafted) was because he tore his UCL twice. He had Tommy John surgery once and then tore the UCL after just one pitch back. So rather than have a second Tommy John he had Platelet Rich Plasma therapy which appears to have done the trick.
He had a 4.00 ERA with 23 strikeouts and eight walks in 27 innings this season. He lacks good secondary pitches, but can pump his fastball into the mid-90’s.
