Rangers left-hander Wes Benjamin took advantage of first-inning home runs from Rougned Odor and Ronald Guzmán to earn his first Major League win in a 5-2 victory over the Athletics in Game 1 of a doubleheader on Saturday at Globe Life Field.

Odor hit a three-run home run and Guzmán hit a two-run shot to give the Rangers a 5-0 lead after right-hander Nick Goody, serving as an opener, set down the A's in order in the top of the first.

That set the stage for Benjamin, who came on in the second inning with his first Major League win sitting in front of him.

“I would be lying to you if I wasn’t thinking about it,” Benjamin said. “But at the same time, I try not to look at the scoreboard. I knew the second inning was mine and I was preparing to go in like a start, eat as many innings as I could. That meant more. The more innings I got as opposed to how many runs I may or may not have given up. That was my main focus.”

In the seven-inning game, Benjamin went four-plus innings and allowed two runs on three hits and one walk while striking out four. He threw 58 pitches and now has a 4.38 ERA in five Major League games.

“It was pretty impressive,” manager Chris Woodward said. “This kid has a ton of belief in himself and executes his pitches, and you see the quality. He gets a lot of weird swings. He uses all parts of the plate and he executes pitches. You see the conviction. This is not an easy lineup, and he mowed through them relatively easily. Really impressive.”

The Rangers broke out early against Oakland right-hander Daulton Jefferies, who was making his Major League debut, and walked two of the first four batters he faced. Odor then ripped an 0-1 changeup over the right-field wall for his second home run in as many games.

Elvis Andrus followed with a single, and Guzmán crushed a 1-2 pitch over the right-center wall. Per Statcast, Guzmán’s home run had a 110.8 mph exit velocity and a 431-foot estimated distance

The home runs marked the first time the Rangers have hit first-inning homers at Globe Life Field this season. The only other two first-inning shots were by Shin-Soo Choo, twice on the road. Both of those came leading off the inning.

“It is a lot easier when you are playing ahead 5-0 in the first inning,” Woodward said. “That is what has been happening to us on the flip side. That’s what I have been talking about, stringing it together, and we have been better at it lately. We have fed off each other and had rallies like that. That’s something we weren’t doing early in the year.”

The home runs also came with two outs. Entering Saturday’s doubleheader, the Rangers had hit just seven of their 39 homers with two outs. They had hit 18 with nobody out and the other 14 with one out.

The Rangers have now hit three straight home runs with a runner on base, including the two-run shot delivered by Odor in the eighth inning on Friday night. That one ended the Rangers’ streak of 18 consecutive homers without a runner on base -- the longest such streak in club history.
