Johnny Cueto pitched a five-hitter to become the NL's first 13-game winner, and the San Francisco Giants beat the Colorado Rockies 5-1 on Wednesday night to move atop the major league standings. San Francisco (54-33) passed the Chicago Cubs (52-32), who lost to the Cincinnati Reds earlier in the day. Voted to the All-Star Game for the second time and a candidate to start in next week's Midsummer Classic, Cueto (13-1) allowed one run on seven hits with eight strikeouts and one walk while going the distance for the fourth time this season.
