(The Sports Xchange) - Pinch-hitter Alejandro De Aza's sacrifice fly scored Marlon Byrd from third base in the bottom of the 12th inning Monday night as the San Francisco Giants kept their slim playoff hopes alive by beating the Los Angeles Dodgers 3-2. Right-hander Jake Peavy pitched seven strong innings and catcher Trevor Brown had a two-run double as the Giants (82-74) kept the Dodgers (87-69) from clinching the National League West, trimming their lead to five games with six remaining. L.A., which has lost four in a row, can clinch its sixth division title in the past 10 years Tuesday when ace left-hander Clayton Kershaw opposes reigning World Series Most Valuable Player Madison Bumgarner of the Giants.
