Rapid Reaction: Mariners 6, Rangers 2

ARLINGTON, Texas -- The Seattle Mariners defeated the Texas Rangers 6-2 to take the first game of this brief two-game series. More thoughts here:

How it happened: Mariners starter Hisashi Iwakuma pitched eight innings and allowed just two runs on six hits, throwing efficiently and relying on his defense. He collected a bunch of ground balls or soft popups and didn't get caught in many long at-bats. Iwakuma's ERA dropped to 1.76 in the process. The Rangers scored two or fewer runs for the eighth time in the last 14 games. They are 4-10 during that stretch.

What it means: Texas couldn't start a winning streak after beating the Toronto Blue Jays on Sunday. Texas has won consecutive games just once since sweeping the Oakland Athletics April 21-23 in California. The Rangers will be at least seven games behind the A's in the AL West and could be eight back if the A's beat the Tampa Bay Rays on Tuesday.

Third-inning trouble: Colby Lewis allowed three hits in the first two innings, but worked around them and didn't yield a run. But things got away from him in the third. Eight Mariners came to the plate and four of them scored without an extra-base hit. Four singles, two walks and a sacrifice fly helped Seattle take a 4-1 lead. It also drove Lewis' pitch count up. He hit 95 pitches after just five innings.

Six-inning mark: Lewis managed to get through the sixth inning, which was a nine-pitch, 1-2-3 frame. That was big for Lewis, who hadn't gotten through six full innings all season. And with his injuries last season, it's the first time he's done it since June 17, 2012, in a win over the Houston Astros.

Beltre blast: Adrian Beltre hit his fourth home run of the season in the second inning. It came moments after he came up with a terrific defensive play, making his patented charge for the ball on a bunt attempt and retiring Kyle Seager with an accurate, off-balance throw.

Rally killer: Texas scored a run in the fourth and was threatening for more to try to get back in the game. With runners and first and second, Mitch Moreland, one of the club's better hitters with runners in scoring position this season, came up and hit into a 4-6-3 double play, ending the inning and the threat.

No Prince: Prince Fielder was in the lineup before batting practice but didn't stay in it for long. He was scratched as he felt some weakness in his arm, though he said he didn't have any pain after a nerve-root injection to relieve his stiff neck. The Rangers will wait to see how he feels on Wednesday; but with a day game, they may elect to rest him again and see if he can play in Detroit.

Up next: RHP Chris Young (3-1, 3.22 ERA) goes up against Rangers' RHP Nick Tepesch (0-0, 1.69 ERA) at 1:05 p.m. at Globe Life Park. It's the club's last home game until June 3, when Chris Davis, Nelson Cruz, manager Buck Showalter and a bunch of other former Rangers come to town wearing Baltimore Orioles' jerseys.
