The San Francisco Giants were counting on coming back to the Bay Area and building some momentum from two impressive wins at San Diego last weekend. For the past three weeks Ketel Marte's tender left hamstring has limited him to designated hitter for the Diamondbacks, but his hustle to beat out a throw wound up keying a rally in Arizona's 4-3 win against the scuffling Giants on Monday night. Marte was safe at first in the third inning on an attempted inning-ending double play, and Daulton Varsho hit a two-run single four batters later to make it 3-0.
