Baltimore @ San Francisco preview

Last Meeting ( Aug 12, 2016 ) Baltimore 5, San Francisco 2

Madison Bumgarner is winless in five starts since the All-Star break and attempts to get back in the victory column when the San Francisco Giants host the Baltimore Orioles on Saturday. San Francisco has lost all five of Bumgarner's starts during the stretch and is just 8-17 since the break after losing 5-2 to the Orioles in Friday's opener of the three-game set.

The Giants managed to retain a one-game lead over the Los Angeles Dodgers in the National League West despite the series-opening defeat while Baltimore moved one-half game ahead of Toronto in the American League East. Mark Trumbo smacked his major league-leading 33rd homer of the campaign and Chris Davis went deep for the 24th time. Baltimore's Adam Jones recorded two hits and an RBI on Friday and is 16-for-35 with two homers during his eight-game hitting streak. San Francisco's Hunter Pence notched a double in the opener but is a meager 3-for-27 with 14 strikeouts over his last seven games.
