Exactly one month after fracturing the tip of his left thumb, Padres third baseman Chase Headley returned to the lineup on Wednesday.

Headley, who led the National League in RBIs (115) a year ago, was reinstated from the 15-day disabled list before the final game of a three-game series against the Dodgers.

"We're very excited for him to be back," Padres first baseman Yonder Alonso said Tuesday.

To make room for Headley on the roster, the Padres placed center fielder Cameron Maybin on the 15-day disabled list with an impingement of his right wrist.

Maybin, who is hitting .091 in 33 at-bats, was in the starting lineup Tuesday, but was a late scratch. San Diego manager Bud Black indicated after the game that Maybin's right wrist, which has troubled him in the past, was sore.

Headley, who won a National League Silver Slugger Award and Gold Glove Award last season, appeared in four games with Class A Lake Elsinore of the California League. He had one hit in three at-bats on Tuesday and played five innings at third base. He was 3-for-12 in the four games.
