The 20-year-old rookie has been on the shelf for two months due to a torn sagittal band on his left ring finger, but he looked healthy while going 3-for-11 during a three-game rehab assignment. Griffin has acclimated well in his first taste of the majors this year, posting a .276/.332/.404 slash line with five homers, 20 steals, 25 RBI and 35 runs through his first 59 big-league contests. He is starting at shortstop and batting sixth in Friday's series opener against the Angels.

Griffin has rejoined the Pirates in Pittsburgh after going 3-for-11 in three rehab games, and he will return to the active roster Friday on the first day he's eligible. The rookie shortstop has been sidelined for the past two months with a torn sagittal band on his left ring finger. With Griffin taking back over at shortstop this weekend, Jacob Gonzalez could be mixed in some at third base down the stretch for the Pirates.
