Rodriguez remained winless in his six home starts after a 13-0 loss to the Los Angeles Angels on Saturday night, the Rangers' fifth straight loss overall in their ballpark and their most lopsided shutout loss anywhere in 12 years.
"We haven't swung the bats the way we liked too. ... We didn't score runs. We pitched poorly," frustrated manager Jeff Banister said. "We've got to be better."
"We created a lot of good situations, and when guys got on into scoring position, we were hitting the ball hard," manager Mike Scioscia said. "It all added up to an incredible offensive night. It's good to see."
Santiago (5-4) scattered three hits and struck out three with one walk, improving to 5-0 with a 1.64 ERA in eight career games (six starts) on the road against the Rangers.
Even with his 2.40 ERA this season, the left-hander hadn't won since May 29. He left after 104 pitches with a 13-0 lead — matching the number of runs the Angels scored combined while he was still on the mound his previous seven starts.
The loss to start the second half of the 162-game schedule for the Rangers dropped them to 41-41 overall. They are 15-21 at home and 26-20 on the road.
Texas' last eight games before the All-Star break are at home, including these first two games against the Angels.
"They're one ballgame. Each one of them. They don't feel good," Banister said. "No we haven't played the way we want to play the first two games, not at all, but to say that's the determining factor of how we go forward, absolutely not."
Rodriguez, who gave up five runs in five innings, is 0-4 with a 7.42 ERA at home for Texas. Like the Rangers, the 36-year-old lefty is better on the road — he's 5-0 with a 2.23 ERA in eight starts away from their ballpark.
"I'm always winning on the road. I want to win over here, too, so I try every time to do the best I can. I don't know," Rodriguez said. "I need to try something better. I think it's the mound when I'm landing I don't feel comfortable. That's the only thing. I feel good. I feel great. My arm's strong."
ANGELS GOOD IN TEXAS
Los Angeles has won 13 of its last 15 games in Texas since the start of the 2014 season.
AT LEAST TROUT WAS HITLESS
While Mike Trout was the only Los Angeles starter without a hit, Erick Aybar went 3 for 4 a night after his first career five-hit game. Nine Angels had hits, including Efren Navarro in his only at-bat after taking over at first base for Albert Pujols, who had a two-run double. Kole Calhoun had a solo homer and a sac fly to get multiple RBIs for the second straight night; he had four RBIs in the series opener.
Angels: RHP Jered Weaver (left hip inflammation) threw more than 50 pitches in a bullpen session without any issues.
Rangers: LF Josh Hamilton was out of the lineup as planned after consecutive games. Banister said Hamilton, who this week came off the DL after a month because of a strained left hamstring, had general lower body soreness. ... OF Delino DeShields (left hamstring strain) said he feels "pretty normal" and has had no issues during his rehab assignment. He worked out with the Rangers before the game.
Angels LHP C.J. Wilson (6-6) vs. Texas RHP Colby Lewis (8-3) in a matchup of starters who were both in the Rangers rotation for their 2010 and 2011 World Series appearances. Wilson is 1-2 with a 6.59 ERA in 10 career starts against Texas since going to Los Angeles as a free agent after the 2011 season.
