Schumaker had been on the disabled list since May 31, the result of a right hamstring strain he suffered while chasing after a ball in the outfield during the club's series in Atlanta. Expected to miss two to four weeks as a result of the injury, Schumaker ended up being on the shorter end of that window.
He wrapped up a rehab assignment with Memphis on Sunday. In three Triple-A games, Schumaker went 3-for-8. He played both in the outfield and at second base.
The addition of Schumaker gives manager Mike Matheny another option in center field, where Shane Robinson, Adron Chambers and Carlos Beltran have all been sharing playing time. And sure enough, Schumaker was in that spot on Tuesday, as he started and hit eighth.
"I think right now that's the best fit where we have need," Matheny said. "But he's still going to get some time at second base."
Starting center fielder Jon Jay is still on the disabled list recovering from a right shoulder sprain, which he sustained in April. With Jay out and the Cardinals using a designated hitter for the next six games, Schumaker is expected to be a regular in the lineup on this road trip.
Sandwiched between a pair of DL stints, Schumaker hit .321 with a .378 on-base percentage in 29 games. He has an eight-game hitting streak that he'll look to extend on Tuesday.
