ARLINGTON -- Elvis Andrus is out of today's lineup after leaving Saturday's game with lower back tightness, and may not be ready to go when the team opens a pivotal three-game series in Oakland on Monday.
Andrus said he woke up stiff, but was hopeful that treatment throughout the day would help him.
Asked if he could be ready for the Oakland series, Andrus said: "I don't know. I'm going to rush it as much as I can but I want to be healthy out there. I haven't been 100 percent since the second day of the season but at least I've been 80 percent."
Andrus said he is OK swinging the bat with the lower back tightness, but feels it whenever he bends over or has to reach for something.
"It's not that bad, it's happened before to me," Andrus said. "I know what I have to do to get it better."
The Rangers will be patient with Andrus and wait until he's healthy. They're not going to rush him back a couple days too soon and risk losing him for a longer period.
The Rangers have a day game against the A's on Monday, a night game Tuesday and a day game Wednesday. They are off Thursday and then open a three-game series at Anaheim.
"We’re not worried about the importance of a series, we’re worried about the importance of the players who have to play in that series," manager Ron Washington said. "If Elvis is not ready to play, he’s not ready to play."
Here are a couple other notes:
* The Rangers added seven players to the team today when rosters expanded. Lance Berkman, Nick Tepesch, Michael Kirkman and Neftali Feliz were all activated off the disabled list; Cory Burns and Robinson Chirinos were recalled from Triple A Round Rock; and Jim Adduci had his contract purchased from Round Rock.
The Rangers already had an open spot on the 40-man roster, but had to clear two more for the additions of Adduci, Feliz and Kirkman. They released right-hander Justin Miller and designated outfielder Joe Benson for assignment to do that.
* Manager Ron Washington said the team would likely add a couple more players once Round Rock's season is over. Ross Wolf, who spent the majority of the season in the long relief role, will likely be added, and the Rangers could look at bringing back another position player.
