Cody Ransom, who played 15 games for New York before he suffered a severe right quadriceps injury, was reinstated from a rehab assignment at Triple-A Scranton/Wilkes-Barre and rejoined the club at Turner Field.
In a corresponding move, Angel Berroa was designated for assignment.
"This was tough, just because I'd never been on the DL," Ransom said. "I'd never been hurt. This was something new. Once I started playing games, it was better."
Ransom struggled as he filled in for Rodriguez, who was coming back from right hip surgery performed on March 9 and would not return to the lineup until early May.
Ransom batted .180 (9-for-50) before he was injured running the bases in an April 24 game at Fenway Park, and later, he revealed that the quadriceps had bothered him since Spring Training.
"There was something, but I didn't think it was anything near what it ended up being," Ransom said. "I just thought it was a knot. Obviously, it was something more than that. I learned from it -- I'll say something next time. But I just didn't think it was that bad."
Ransom played five extended spring games late last month before he began a rehab assignment at Triple-A on June 4, batting .250 (11-for-44) with nine runs, four doubles, two home runs, eight RBIs and six walks in 14 games.
Ransom played at shortstop, third base and second base while at Triple-A, and manager Joe Girardi said that he expected to use Ransom to spell not only Rodriguez, but also Derek Jeter and Robinson Cano.
"I can play him anywhere in the infield, all four positions," Girardi said. "He'll get some starts."
Berroa, 31, batted .136 (3-for-22) with one double and one RBI in 21 games for the Yankees. The 2003 American League Rookie of the Year was called up after Ransom's injury after he opened the season at Triple-A.
