Chavez appeared in three games for Triple-A Reno during his rehab assignment. Initially, the club planned on having him play more, but D-backs general manager Kevin Towers was impressed with what he saw out of Chavez on Wednesday and expedited the timetable.
That was fine with Chavez, who was reticent about testing his strained oblique at the start of his rehab, but had no such concerns at the end.
"I was real apprehensive, just a lot of doubt," Chavez said of his first game. "The day before I was coming here, I had a check swing and that was really kind of what I was waiting for to see how I felt, and I didn't feel anything."
Chavez arrived just before game time Friday and was in the starting lineup at third base on Saturday. He could also see time at first when -- or if -- Paul Goldschmidt is given a day off.
