Pirates' Yerry De Los Santos: Heads back to minors

The Pirates optioned De Los Santos to Triple-A Indianapolis on Sunday.

De Los Santos will return to the minors following a one-day stint with the big club. He was deployed in relief in Saturday's 4-3 win over St. Louis, retiring two of the three batters he faced on the day. The Pirates selected the contract of right-hander Chase De Jong from Triple-A in a corresponding move.
