"It may be four or five days, it may be three days," Washington said.The Rangers originally considered putting outfielder Endy Chavez on the disabled list with a strained right hamstring muscle. But they reconsidered and sent Davis to Round Rock instead. Texas felt Chavez is close to being able to play in the outfield. With Hamilton at designated hitter, the Rangers have Young, Mike Napoli and Mitch Moreland who can all play first base, and they felt they needed the extra outfielder with Julio Borbon still on the disabled list. Davis was hitting .250 with three home runs and four RBIs since being recalled from Round Rock. He was originally brought up when Hamilton went on the disabled list on April 13. "Chris Davis has performed well and done what we've asked," assistant general manager Thad Levine said. "We see him going to Triple-A and continuing to do what he has been doing. He has every chance of being a productive part of our team at some point later this season." Tateyama was called up to reinforce a bullpen that has a 4.60 ERA for May, as well as three blown saves in the past seven games. Their eight blown saves is the second most in the AL and their 10 blown saves are third most. Tateyama was 1-0 with a 2.14 ERA in 14 relief appearances, holding opponents to a .214 batting average while striking out 26 and walking four in 21 innings. Eppley, a rookie, pitched in 10 games for the Rangers. He allowed six runs in a third of an inning against the Yankees on May 8, but just two runs over 8 2/3 innings in his other nine outings. "We quit finding places to use Eppley," Washington said. "He's young, he's needs to go down and get consistent work. Tateyama has been doing a great job. Hopefully he can give us a shot in the arm. He throws strikes, keeps the ball down in the zone and he has learned about expanding the strike zone. If he continues to do that, he will be effective."
