Twins put lefty Diamond on 15-day DL
Diamond is projected as one of the team's top starters this season after going 12-9 with a 3.54 ERA last year.
The Twins also announced right-hander Anthony Swarzak was put on the 15-day list as he recovers from rib fractures. Swarzak was hurt in January while wrestling with teammates at a fan festival.
