A pair of left-handed hitters will take the hill on Saturday at Fenway Park, with Jon Lester facing off against Brewers veteran Randy Wolf. Only four Brewers batters have faced Lester. Yuniesky Betancourt has had the most success against the hard-throwing lefty. Betancourt is 4-for-10 with one home run, a double, three RBIs and three walks. Josh Wilson, on the other hand, is hitless against Lester in 11 at-bats and has struck out four times.
