WASHINGTON -- Nationals catcher Jesus Flores has a sprained right knee and was listed Monday as day to day.
Flores was injured in a home plate collision in Washington's loss Saturday night to Colorado and did not play Sunday. He was originally diagnosed with a strained right calf, but an MRI exam Monday revealed the injury was in his knee.
Flores leads the Nationals with 52 RBI. He is batting .271 with eight home runs.
