The Philadelphia Phillies have made a case for Zack Wheeler, who is a very good pitching prospect. Before joining the Phillies, Wheeler was considered mildly injury prone and had never pitched more than 200 innings in a season. But he was the hardest-working pitcher in baseball last season, throwing 213.1 innings. And even though Wheeler was injured during the MLB lockout, he was able to recover and pitch a total of 213.1 innings.
