Love the player, hate the juice. The former No. 1 overall draft pick is excelling in the Majors right now, hitting .304 since being called up on April 28th. In his last six starts, Travis Bazzana has posted five multi-hit games. Though he's never faced another former No. 1 overall pick, Casey Mize, I expect Cleveland's second baseman to record at least one hit on Thursday afternoon.
