Here's what I wrote about him after the draft: Round 16: J.R. Mathes Western Michigan University LHP Scouting Report: Senior lefty listed at 6’3” 205, which for a lefty is certainly good size. He works with a sinking fastball that touches 89 and due to his age is unlikely to improve. But even with a fastball that only reaches the high-80’s, he was successful last year nonetheless. He went 6-4 last season as the Western Michigan ace while posting a 3.64 ERA, three complete games and 94 innings pitched. His peripheral numbers were good as well: he whiffed 87 batter while only walking 19 and his sinker worked as evidence by his 4 HR’s allowed. He tossed a shutout and an eight inning 2 run effort against Purdue. Because he doesn’t blow batters away, he’ll need to rely on keeping the ball in the park and making the opposition put the ball in play. As a senior, he should be an easy sign. Personal Analysis: Low-risk, low-reward. Mathes isn’t a guy you project for a frontline starter and as a senior he’ll need to move fast. Due to the cubs outstanding core of arms he may find himself in the bullpen. Making the majors would be an overcoming of odds, and he might find himself as a journeyman in a few years. Mathes was excellent facing younger hitters in Boise last year, so it's good to see him pitch well against a more age appropriate hitters. I think his future is probably in the bullpen. He's still fairly old, but he's a lefty, so he'll get his chance.
