Slumping Choo starts All-Star break early

ARLINGTON -- On the day of his 32nd birthday, Rangers outfielder Shin-Soo Choo wasn't in the lineup against the Angels Sunday, starting his All-Star break a day early.

Choo has been struggling offensively as of late, and Rangers manager Ron Washington said Choo just needs a little bit of a mental boost. He's also been fighting off some pain in a sore left ankle for a few months.

Choo is hitting .244 on the season, but is batting .152 with 11 strikeouts in the past eight games.

In the first three games of the four-game series against the Angels, Choo was 1-for-12 with six strikeouts. Washington hopes his left fielder will be ready to go at the end of the All-Star break and when the Rangers head to Toronto.

"Just got to get himself back mentally," Washington said. "Hopefully these days will rejuvenate him."

Worth noting

• Rangers manager Ron Washington said that pitcher Miles Mikolas will get another start after the All-Star break along with Yu Darvish, Colby Lewis and Nick Tepesch. Mikolas threw for 5 2/3 innings Saturday against the Angels with nine hits and five runs, four of which were earned. All four of the earned runs came in the sixth inning.

• Rangers shortstop Elvis Andrus recorded his 20th steal Saturday against the Angels. He leads the team and is fifth in the A.L. He's now had six seasons with at least 20 steals, which is the most 20-steal seasons in Rangers history.

• The Rangers' seven straight losses entering Sunday were a season-high. The last time they dropped seven in a row at Globe Life Park was between Sept. 1-15 in 2013.
