ARLINGTON, Texas -- Despite the best efforts of Texas Rangers slugger Adrian Beltre, who seems to be a thorn in the side of the Orioles every time the teams meet, the Orioles emerged from Wednesday’s back-and-forth game with their fourth straight win.

The Orioles’ 6-5 victory over the Rangers earned a series win here in Texas and guaranteed that they would complete their three-city, 10-game road trip with at least a .500 record.

The Orioles (30-27) have scored 27 runs with 50 hits over their last four games. In the first two games here in Texas, they have scored 14 runs with 30 hits, outlasting the Rangers in the later innings both nights. They had 13 hits Wednesday.

"We just keep grinding through the road trip,” Orioles manager Buck Showalter said. “I've said 100 times about trusting the track record and it will happen. It's just too many good players with good skills. It's just kind of frustrating because you want it to be there every night, and as much as you work toward it to be perfect, it's not always that way."

On Wednesday, the first four hitters in the Orioles lineup were 9-for-18, led by leadoff hitter Nick Markakis, who was 2-for-3 with a homer and two walks and drove in the game-winning run.

Markakis’ two-out, opposite-field RBI single in the sixth off left-handed reliever Aaron Poreda broke a 5-5 tie and was the edge in a game that also included four homers and its share of defensive and base-running miscues on a muggy Texas night.

“I’ve liked the offense all season,” Markakis said. “We’ve been doing what we need to do. ... Everybody’s been having good at-bats up here. It seems like when they’ve been throwing it over the plate, we’ve been putting good swings on it. We’ve been able to find the hole and find the gap. We don’t need to change anything.”

Beltre hit two homers and drove in five runs, giving him nine homers and 18 RBIs over his last 10 games against the Orioles. It was his third five-RBI game in that span.

Beltre’s three-run homer off right-hander Bud Norris tied the game at 5 in the fifth inning and sparked life into the announced crowd of 27,934 at Globe Life Park in Arlington. Beltre also hit a two-run homer off Norris in the first inning.

The game-tying homer came right after Mitch Moreland’s comebacker hit Norris on the right forearm. After Showalter and head athletic trainer Richie Bancells ran to the mound to check on Norris, he remained in the game after three warm-up pitches.

Norris then delivered a high-and-outside 1-2 fastball that Beltre swatted into the Rangers bullpen to tie the game.

“I got ahead in the count, 0-2, he fouled off a couple fastballs, and he fouled off the good slider that I threw,” Norris said. “So, I’m trying to climb the ladder a little bit. He put another good swing on it. He’s locked in right now. It’s all you can say right now.”

Norris (4-5) left the game after that inning with a right forearm contusion after 99 pitches. The five runs he allowed tied a season-high, and his five innings matched his season-low, both occurring in his first start of the season on April 5 in Detroit.

“Pretty sore,” Norris said of his forearm. “You never want to get smoked by a comebacker, but the trainers will look at it the next couple days and get rid of the swelling as best I can.”

Norris said he hoped he would be able to make his next start, but he was uncertain.

“I don’t know, I really got to see how it is tomorrow,” Norris said. “The swelling is really going to come tomorrow, so talking to Richie, he was like ‘Let’s put some ice on it. Let’s get a compression sleeve on it, and we will monitor the swelling the next couple days.”

The Orioles bullpen held the Rangers scoreless over the final four innings.

Despite allowing two hits in the ninth, Orioles closer Zach Britton converted his fifth save in six opportunities with a scoreless inning.

Elvis Andrus pushed a bunt toward second base for a single, but Shin-Soo Choo hit the first pitch he saw to shortstop J.J. Hardy for a 6-4-3 double play.

Britton then allowed a looping single to right field by Luis Sardinas, but struck out pinch-hitter Michael Choice on three pitches to end the game.
