Duran is expected to be replaced by third baseman Travis Metcalf, who started the season on the disabled list because of hamstring surgery. He is currently hitting .238 with no home runs and eight RBIs in 11 games at Triple-A Oklahoma.Loe is expected to make room for pitcher Kevin Millwood, who is coming off the disabled list to start on Friday against the Athletics. Doug Mathis, who was in the starting rotation while Millwood was out, will move to the bullpen.
In addition to 12 starts at the hot corner, Duran also saw time at left field, right field and second base for the Rangers, proving to be a valuable utility man for the club.
However, his recent slump left the Rangers in a bind, as manager Ron Washington acknowledged on Monday that Duran would benefit from daily playing time.
In 10 games with Oklahoma, Duran batted .250 (10-for-40) with two doubles, two triples and an RBI this season.
