Facing Rays left-hander David Price, Davey Johnson will send out what's become his typical lineup against lefties.
Danny Espinosa will lead off, Michael Morse will hit cleanup and Adam LaRoche will be bumped down to the No. 5 spot.
In addition, Tyler Moore will start in left field, hitting seventh.
Here's how the lineup will look tonight:
2B Danny Espinosa
CF Bryce Harper
3B Ryan Zimmerman
RF Michael Morse
1B Adam LaRoche
SS Ian Desmond
LF Tyler Moore
C Jesus Flores
P Chien-Ming Wang
In other notes, reliever Henry Rodriguez will begin a rehab assignment with Triple-A Syracuse tonight. Rodriguez landed on the DL on June 7 (retroactive to June 6) with a strained index finger on his right hand.
Reliever Cole Kimball also began a rehab assignment today, marking a major step in his comeback from rotator cuff surgery, which he underwent last July. Kimball pitched a scoreless inning for the Gulf Coast League Nats today.
