Phillies' Michael Mercado: Optioned to minors

The Phillies optioned Mercado to Triple-A Lehigh Valley on Monday.

Mercado, whom the Phillies acquired from the Rays in November, occupies a spot on Philadelphia's 40-man roster but has yet to make his big-league debut. He'll likely occupy a spot in Lehigh Valley's bullpen and will look to distinguish himself with the hope of earning a call-up to the Phillies.
