Extra Bases: Washington explains ending

HOUSTON -- Alex Rios is sitting out a few days because of a sprained right ankle.

Friday night, he walked slowly into the trainer's room with his ankle and right hand wrapped.

Rios, the Texas Rangers' starting right fielder, is nicked up and trying to get healthy not only for this team, but possibly for another if he gets traded.

Rios was available to pinch-hit against the Houston Astros on Friday night but didn't, particularly in a critical situation of the game.

In the ninth, trailing 4-3, the Rangers had the tying and go-ahead runners on base with one out. Washington elected to keep Daniel Robertson in the game to face Astros closer Chad Qualls.

Righty versus Righty.

Why not send Rios up, a better hitter?

"'Cause they had a lefty going on [in Tony Sipp in the bullpen] out there, and that guy is struggling," Washington said. "And I had [Rios] ready for [Jim] Adduci."

Sipp gave up a grand slam in Thursday's loss to the Philadelphia Phillies, and if he relieves Qualls, Rios enters the game.

Robertson bounced into a game-ending 4-6-3 double play.

"Robbie had a tough at-bat," Washington said.

You can question the decision, but it made sense for all the right reasons because Washington wanted to get a strong right-handed hitter up against a lefty coming off a poor outing.

Choo's mistake: A fly ball hit by Robbie Grossman landed between right fielder Shin-Soo Choo and Rougned Odor in the sixth inning. While it didn't cause any damage, Washington wasn't pleased with the play.

Odor, the second baseman, came running to right field and at the last second stopped allowing the ball to fall helplessly to the ground for a hit.

"It's his ball all the way," Washington said of Choo, who was playing deep.

Cotts suffers the loss:Left-handed reliever Neal Cotts (2-6) took the loss on Friday night and was credited with his sixth blown save of the season. Cotts is a dependable relief pitcher for the Rangers, but he gave up a two-run, go-ahead homer to Grossman in the eighth inning.

"Grossman, I tried to throw a fastball away and it came back over the middle," Cotts said.

He pitched 3 2/3 scoreless innings, spanning three games before Grossman's homer. In his past 14 games, heading into Friday night, Cotts allowed just three earned runs over 14 innings.

His good stretch ended Friday night.

"I made some mistakes," he said. "Just didn't put them away."
