SAN FRANCISCO -- Poor defense behind Scott Feldman and another forgetful performance at the plate sent the Rangers to a 5-2 loss to San Francisco that recuded their lead in the American League West to three games.
The Rangers committed three errors, two of which led to runs behind Feldman. A third error, on a pickoff throw by Koji Uehara, led to a third gift-wrapped run as the Rangers lost for the sixth time in nine games on this West Coast road trip.
Feldman (0-5) allowed three runs (two earned) on four hits and a walk in 5 1/3 innings, his longest and best outing of the season as a spot starter. But he was no match for Ryan Vogelsong, who took a shutout into the eighth inning before Mitch Moreland ended it with a pinch-hit solo shot.
Mike Napoli hit a solo shot with two outs in the ninth inning.
Vogelsong helped get the Giants' offense started in the third inning. He singled with one out, went to second on a balk and was at third after Gregor Blanco singled.
Feldman, though, would do his job as he got Ryan Theriot to hit a grounder toward second base. Ian Kinsler fielded it, but Blanco stopped to avoid the tag. Kinsler then opted to get an out at first base, but threw wildly and got no outs as Vogelsong scored.
The run was earned, because a double play can't be assumed, but it was the third time in five starts that an error had cost Feldman. Adrian Beltre made gaffes May 14 and May 29 that led to unearned runs being charged to Feldman.
The mistakes don't just cost Feldman runs, but they also force him to throw more pitches. It has been a struggle for Feldman to get through five innings, and the fielding miscues haven't helped.
San Francisco scored again in the fifth as the defense again suffered a lapse. Josh Hamilton was tagged with a two-base error in left field after losing a Brandon Crawford flyball in the sun. Feldman got the next two batters, but Theriot lofted a flare into right field that fell for a single and a 2-0 Giants lead.
Feldman would be charged with another run in the sixth. Nate Schierholtz tripled off Robbie Ross to plate Angel Pagan, who Feldman had walked with one out before being pulled at 91 pitches.
Four of the Giants' runs, including the two they scored off Uehara in the seventh, came with two outs.
The Rangers, meanwhile, were nearly shut out for the second time since Wednesday. Elvis Andrus and Adrian Beltre had hits in the first inning, but the Rangers didn't have another hit until Mitch Moreland started the eighth with a shot into McCovey Cove.
