JJ to throw three innings

VIERA, Fla. — Marlins ace Josh Johnson, who will pitch in the April 1 season opener, is expected to throw three innings or around 55 pitches on Wednesday against the Nationals at Space Coast Stadium.

Greg Dobbs was supposed to be the designated hitter, but he was scratched because of a sore knee. Dobbs was shaken up on Tuesday when he had a collision at first base. He should be fine.

The Nationals are starting lefty John Lannan.
