Bad stuff happens to the Rockies in San Francisco. Case in point: In the sixth inning of Sunday afternoon’s game at Oracle Park, Rockies third baseman Ryan McMahon tagged Derek Hill for what should have been the third out. Instead, the impact of the tag dislodged the ball from McMahon’s glove. McMahon’s error loaded the bases, and Matt Chapman delivered a two-run single on Noah Davis’s next pitch to put San Francisco ahead, 5-2. The Giants held on to win the game, 5-4, swept the four-game series and beat the Rockies for the 12th consecutive time at Oracle Park.
