Michael Young hit a home run with nobody on base in the fourth inning, the Rangers' 13th consecutive solo home run. They haven't hit a home run with a runner on base since Ian Kinsler's three-run home run on June 5.
Getting big hits with runners in scoring position or just with men on base has been a huge glitch in their once-mighty offense and a significant factor why they've lost nine of 16 this month. With the Angels winning their seventh straight Friday night, the Rangers are now down to a half-game lead in the American League West.
"We can't worry about the Angels," outfielder Marlon Byrd said. "They're going to win games, it's as simple as that. If we win, we'll be fine. If we don't and they get on a streak, they'll catch us. That's where we're at. We just need to take care of our business.
The Rangers, speaking of dubious club marks, are now 0-7 in Interleague Play at AT&T Park, the most games without a win in any park they've ever played.
The loss also ended Scott Feldman's four-game road winning streak. He was trying to become the first Rangers pitcher in team history to win his first five starts of the season on the road but instead let a 4-3 lead slip away in the bottom of the sixth inning when Fred Lewis hit a two-run home run with two out.
The Rangers had just taken the lead in the top of the inning and second baseman Ian Kinsler, with runners at the corners and nobody out, had just made a nice catch in short right field to get a doubled-up double play at first base.
That left Feldman with a runner at third with two out in what clearly would have been his last inning. But he left a 2-0 cut fastball up and on the plate, and Lewis belted high over the right-field wall to give the Giants a lead.
"I was thinking that, even giving up three runs before that, that it still would have been a good outing if I had gotten out of that inning with the lead," Feldman said. "That's disappointing. I've got to do a better job of finishing that inning."
Feldman, who allowed five runs on eight hits and a walk while striking out five, is now 5-2 with a 4.02 ERA on the season. He did last longer than Randy Johnson, the Giants left-hander who was denied his 302nd career victory. Johnson was up, 3-1, in the sixth but the Rangers scored three off him and reliever Brandon Medders to give the Rangers a lead.
Nelson Cruz had an RBI single and Byrd ripped a two-run double in the inning, but that represented the Rangers' sum total of clutch hitting on the night.
The Rangers were 3-for-13 with runners in scoring position (including an infield hit by Andruw Jones that did not score a run) and twice were unable early to get a runner home from third base with one out. Kinsler led off the first with a double and was bunted to second by Elvis Andrus. But Johnson came back to strike out Young and Jones to keep Kinsler at third.
In the second inning, Hank Blalock tripled with one out, but this time Johnson got Byrd on a foul pop and struck out Jarrod Saltalamacchia.
"The two we needed most were the ones we didn't get in the first and second inning," Rangers manager Ron Washington said. "Those were the ones that came back to haunt us."
The Rangers also missed another chance in the seventh after a leadoff walk by pinch-hitter Brandon Boggs and a one-out single by Andrus off reliever Merkin Valdez.
Right-hander Sergio Romo took over and squelched the threat by striking out Young and -- after Jones' infield single -- getting Nelson Cruz on a weak popup.
The Rangers are now hitting .218 with runners in scoring position for the month of June and .261 overall for the season, fifth lowest in the American League.
"We've got to pick it up," Byrd said. "It has not been a good month. We've got to pick it up. One through nine, we've got to do a better job. Our pitching has been keeping us in it; hopefully we can start picking it up."
