Brewers right-hander Junior Guerra (calf) to miss at least six weeks

Brewers Opening Day starter Junior Guerra was forced to leave his Monday start against the Rockies in the bottom of the third inning with a right calf injury. He was hurt while attempting a sacrifice bunt.

Before departing, Guerra surrendered two runs in his three frames of work. Veteran left-hander Tommy Milone replaced him in the top of the fourth inning. Following the game, manager Craig Counsell confirmed Guerra suffered a “significant” strain in his right calf and will be sidelined “at least” six weeks. Guerra was placed on the 10-day disabled list, and Milone will take his place in the rotation.

It’s a big loss for a Brewers team that many think will outperform low expectations. The late-blooming 32-year-old Guerra posted a splendid 2.81 ERA, 1.13 WHIP and 100/43 K/BB ratio across 121 ²⁄₃ innings last season. In addition to Milone, the rest of the Brewers’ rotation consists of Zach Davies, Chase Anderson, Wily Peralta, and Jimmy Nelson. Matt Garza (groin) will begin a rehab assignment next week.
