Suarez was optioned to Triple-A Lehigh Valley on Thursday.
The Phillies brought up a fresh arm in Yacksel Rios to replace Suarez after the club's bullpen was heavily taxed in a 24-4 shellacking in Game 1 of Thursday's doubleheader. Suarez got the start in that outing and surrendered four earned runs on 11 hits across four innings. He'll return to the Lehigh Valley rotation for the time being.
