The Milwaukee Brewers have had at least a share of first place in the National League Central every day since April 5, but that could change after Sunday's series finale against the host Washington Nationals. The Brewers head into the rubber match of the three-game set tied with St. Louis for the division lead, and they're hoping for a strong outing from Yovani Gallardo after Matt Garza recorded just one out in Saturday's 8-3 loss. They'll be tested again by a Washington team that has won 11 of its last 16 to move into a tie with Atlanta atop the NL East.The Nationals pounded out 12 hits in Saturday's rout, but Adam LaRoche was the only starter without one and is mired in an 0-for-17 slump. Milwaukee reliever Will Smith was unavailable on Friday due to back spasms, but he proclaimed himself ready Saturday after receiving treatment. Smith has been a key setup man for the Brewers, who are hoping to get Jim Henderson (right shoulder) and Tyler Thornburg (right elbow) back in the bullpen over the next few weeks.TV: 1:35 p.m. ET, FSN Wisconsin (Milwaukee), WUSA 9, MASN (Washington)PITCHING MATCHUP: Brewers RH Yovani Gallardo (5-5, 3.68 ERA) vs. Nationals LH Gio Gonzalez (6-5, 3.56)The All-Star break came at a good time for Gallardo, who has allowed a total of 15 runs (12 earned) in 17 1/3 innings over his last three starts.
