Hundley took a morning flight Wednesday to San Diego from Tucson, where he had been on a four-game rehabilitation stint with the Padres' Triple-A affiliate.
"I'm ready to roll," said Hundley, who was hitting sixth against the Rockies.
Hundley, the Padres Opening Day catcher, hit .273 in 11 at-bats with Tucson, hitting one home run and knocking in five runs. More importantly, he tested his oblique in just about every way imaginable.
"I got a chance to catch with a lot of [baserunners] on, I threw to the bases a bunch and got a few at-bats," Hundley said. "[The oblique] feels good."
Hundley suffered the oblique injury taking a swing in a game against the Pirates on May 4. He was hitting .263 with three home runs and 12 RBIs in 95 at-bats at the time of the injury.
"He had four good days in Tucson, and felt good about his oblique," Padres manager Bud Black said. "He had good at-bats, and [Tucson manager Terry Kennedy] said he looked good behind the plate."
The corresponding roster move saw the Padres optioning outfielder Blake Tekotte back to Double-A San Antonio.
Tekotte hit .158 in 19 at-bats since he had his contract purchased on May 23. He got his first Major League start on May 28 in Washington, and proceeded to reach base three times in that game, getting his first two Major League hits.
"Blake needs to go back and play," Black said. "But it was great he got exposure to the Major Leagues."
The Padres will, for the time being, carry three catchers, including Rob Johnson and Kyle Phillips, who handled the catching duties while Hundley was out.
"It does give us some flexibility there, Kyle's being left-handed gives us an [extra] bat," Black said.
