Rapid Reaction: Mariners 10, Rangers 3

ARLINGTON, Texas -- The Texas Rangers had some defensive issues and bullpen problems and the Seattle Mariners took advantage, turning a one-run game into a runaway with a six runs in the eighth, which also featured one costly error and a wild pitch. Texas allowed four unearned runs in the game.

What it means: The Rangers' four-game win streak comes to an end. They'll attempt to win the series on Wednesday night. ... The six runs allowed in the eighth matches a season high allowed by Texas (fourth inning May 2 at Toronto). ... The 10 runs ties a season high for the Mariners. ... It was the most lopsided loss of the season for Texas.

Doomed defense: Texas wasn't good on defense. It started in the fifth with the bases loaded and two outs (the Rangers had intentionally walked Ichiro Suzuki to load them and face Jesus Montero). Scott Feldman got the ground ball he needed to third. But Adrian Beltre threw it into the Rangers' dugout, allowing two runs to score to give the Mariners a 4-1 advantage. Beltre was looking at his hand right after the error, perhaps indicating the ball just slipped right out of it. It was his fifth error of the season.

Elvis error: The Rangers had the infield in with the bases loaded and no outs in the eighth and Elvis Andrus got a ground ball hit right at him. But it appeared he was thinking about throwing home before gloving it cleanly and he bobbled it. Everyone was safe and the Mariners had extended the lead.

More defensive issues: Nelson Cruz misjudged a ball to right in the eighth and it dropped, allowing yet another run to score. It just wasn't a crisp defensive night for Texas. ... Mark Lowe threw a wild pitch that scored a run in the eighth. ... Cruz did have a nice double play, though that might be because he got a late jump. He made a running catch in the seventh and doubled up Dustin Ackley, who probably thought Cruz wasn't going to get to it.

Feldman can't get through five: Feldman has made four starts this season and has yet to get through the fifth inning. Beltre's error didn't help him as he was taken out after that in favor of lefty Robbie Ross, who came in to face left-handed hitter Kyle Seager. Ross got him to ground out. Feldman ended up allowing four runs (two earned) on four hits in 4 2/3 innings with three walks and three strikeouts.

Wasted chance: Brendan Ryan, the Mariners' shortstop, couldn't find Yorvit Torrealba's popup in the fifth inning, putting runners at first and second. Craig Gentry walked to load the bases. But on the first pitch, Ian Kinsler grounded into a 6-4-3 double play.

Two-out homer hurts Feldman: The Rangers didn't hold their 1-0 lead for long as Feldman gave up a two-run home run (405 feet to center) to John Jaso, a left-handed batter. It was Jaso's second homer of the season. Coming into the game, lefties were just 5-for-38 against Feldman with no homers. The last time a lefty hit a homer off Feldman was Sept. 28, 2010 when Justin Smoak, also of the Mariners, hit one off him.

Hamilton homer: Josh Hamilton, who wasn't feeling 100 percent with upper respiratory issues, hit a home run to straightaway center field in the sixth. Andrus was on base in front of him, turning a 4-1 game into a 4-3 game. Hamilton had three RBIs, pushing his major league-leading total to 56.

Slow roller delivers: Hamilton can drive in runs in a variety of different ways. In the first inning, it was a slow roller just inside the first-base line. After taking some weak swings to get to a two-strike count, Hamilton was able to get just enough on a ball to get it down the line and score Andrus from third.

Ogando struggling: Alexi Ogando has now allowed a run in five of his last six outings, including two in the eighth inning Tuesday. In 8 1/3 innings, he's allowed 10 hits, seven runs, three walks and six strikeouts.

Roy Oswalt agrees to terms: The Rangers announced during the game that they had a deal in place with the free-agent pitcher pending a physical Thursday. Read more here.

Tidbits: Gentry was fun to watch in the seventh with two outs, when everyone knew he was trying to steal second. He got it done anyway, a nod to his tremendous speed. But he was stranded there. ... The Rangers had 34, 531 for a Tuesday night against Seattle. It was the club's lowest attendance since April 12, also against Seattle. That shows how great the attendance has been this season. ... Beltre's double in the eighth extended his hitting streak to eight games.

Up next: The final game of this three-game series with the Mariners features Derek Holland, likely without his mustache, against right-handed pitcher Blake Beavan.
