The Cubs have tabbed left-hander Brett Anderson to open the season as their fifth starter, tweets Patrick Mooney of CSN Chicago. Consequently, fellow southpaw Mike Montgomery, whom Anderson beat out, will head to the bullpen. At $3.5MM, Anderson received one of the biggest contracts the Cubs handed out during an offseason devoid of free agent splashes for the reigning World Series champions. Given the 29-year-old Anderson’s well-known injury history, though, it stands to reason Montgomery could end up in the rotation this season. “I could see him starting,” manager Joe Maddon told Jesse Rogers of ESPN.
