Holland pleased with latest rehab start

HOUSTON -- Both Derek Holland and Rangers manager Ron Washington were pleased with Holland's latest rehab start. On Saturday, the left-hander threw three scoreless innings for Double-A Frisco versus Tulsa.

Holland allowed three hits with four strikeouts. He threw 49 pitches, 30 for strikes, as he recovers from left knee surgery on Jan. 10.

"He did a good job, three innings," said Washington. "Progress. Once again it's all about how consistent you can be. If he can continue on that road into his next start, and continues into [the following] start, then we'll make an assessment as we get closer to September.

"It is encouraging. Not only for us, but for him also, coming off the injury. But he has to keep pitching, keep improving."

Following Saturday's game Holland said, "I felt really good. The big thing was I commanded my fastball better. I got back in the zone. I'm disappointed fastball-wise, but command was great, offspeed was good. Good tempo."

In his three rehab starts between Frisco and Triple-A Round Rock, Holland has allowed four runs in six innings. His next scheduled start is Thursday at Round Rock.

Choo aware of milestone hit, calls it impressive

HOUSTON -- Shin-Soo Choo said he's not a counter, or stat freak. He tied his career high of four hits in a game on Saturday, but he isn't certain how many times he's accomplished the feat.

He was aware however that the fourth hit of the game, off Houston's Mike Foltynewicz in the ninth inning, was his 1,000th Major League hit.

"As soon as I leave the clubhouse it's a new game," said the 32-year-old Choo. "I'm not thinking about last night, but still 1,000 hits is impressive."

The main reason Choo said he was aware of closing in on the hit milestone was that he ended the 2013 season with exactly 900 hits.

"Oh, I need 100 more hits for 1,000. That's how I remembered," said Choo. "I'm not really a stat person because it's not really helpful. It was an even number that's why."

The ball hit for Choo's 1,000th hit was retrieved so that Choo, who entered Sunday 9-for-20 in his last five games, can keep the the ball as a memento.

Rios re-injures sprained right ankle on play at plate

HOUSTON -- Alex Rios aggravated his sprained right ankle sliding into home plate in the top of the fourth inning on Sunday against the Astros. He was replaced in right field by Jim Adduci to start the bottom of the inning.

Rios will be re-evaluated on Monday at Arlington, when the Rangers start a seven-game homestand.

Rios, who doubled in Elvis Andrus, scored from second base on a hit to tie the game at 2. As Rios slid towards home plate, he knocked the ball loose from catcher Carlos Corporan.

As soon as Rios stood up it was obvious something wasn't right physically. He walked toward the Rangers dugout gingerly.

Rios was making a start in right field after sitting out the first two games of the series at Minute Maid Park, in an attempt to give the ankle more time to heal. Rios sprained the ankle on July 19 at Toronto and missed three games from July 20-22 due to the injury.

Adduci's first homer product of selectivity

HOUSTON -- Right fielder Jim Adduci's first Major League home run on Saturday, prompted the media to ask Rangers manager Ron Washington on Sunday if he remembered his first home run in the big leagues.

Washington did, but he didn't collect the ball as a souvenir.

"I didn't get it," said Washington. "They went so far in the stands I don't think they could have found the guy."

The 29-year-old Adduci, who spent 10 years in the Minor Leagues, hit a two-run shot in the sixth inning off Houston starter Scott Feldman in his 96th career Major League at-bat.

However, Washington isn't expecting Adduci to be a power hitter.

"I like Adduci, I like for him to be successful, but I don't think we need to look for Adduci to be a 20 to 25 home run guy," said Washington. "That's not his swing.

"He's another guy that's very selective at what he swings at. He got through that ball pretty good last night."

Adduci joins Michael Choice, Rougned Odor and Brad Snyder as Rangers to hit their first Major League home run in 2014.

Worth noting

• Philadelphia claimed Jerome Williams, whom the Rangers designated for assignment on Friday.

• Outfielder Mike Carp, who left Saturday's game at Houston in the third inning with tightness in his left groin, is improving and is listed as day to day. He wasn't scheduled to be in Sunday's lineup, according to Washington.

• As Washington and Alex Rios had stated days earlier, Rios, who is battling a sprained right ankle, was back in the Rangers lineup on Sunday, playing right field and batting third.

Robinson Chirinos was in the lineup catching right-hander Nick Martinez. Geovany Soto had caught the first two games of the series against the Astros after having been activated from the 15-day disabled list on Friday.
