Shaun Marcum left after one inning and the Milwaukee Brewers dropped their Interleague opener to the Boston Red Sox 10-4 at Fenway Park Friday evening. Marcum threw 44 pitches but allowed only two runs. He didn’t return for the second frame, leaving with a strained left hip flexor. The Red Sox lost left fielder Carl Crawford to an apparent hamstring injury after he legged out an infield single in the bottom of the first; third baseman Kevin Youkilis was also replaced in the fifth inning due to a stomach illness. However the Brew Crew couldn’t take advantage, as John Lackey settled down after a shaky start to retire the final fifteen batters he faced, giving Boston their 12th win in their last 13 games. Brewers left-handed reliever Danny Herrera was designated for assignment after another horrendous outing, allowing four hits, four runs (three earned) and one walk in an innings work, ballooning his ERA to 21.60. Milwaukee looks to end their feebleness at Fenway when they send lefty Randy Wolf (4-4, 3.20 ERA) to the mound to face off against fellow southpaw Jon Lester (9-2, 3.73 ERA).
