The Rangers announced today that outfielder Willie Calhoun is heading to the 10-day injured list with a strained left quadriceps. He’ll be replaced on the active roster by fellow outfielder Delino DeShields.

It’s inopportune timing for the 24-year-old Calhoun, who just got a long-awaited promotion back to the majors. He has been in good form since coming up, slashing .435/.458/.739 with a pair of long balls in two dozen plate appearances.

There’s no reason to think the injury will be more than a speed bump for Calhoun, who was the headlining prospect of the 2017 Yu Darvish trade.
