The Phillies say Oswalt had a neck bruise but did not lose consciousness. The team says he was not dizzy before leaving Wednesday's game against Tampa Bay.
Oswalt fell to the ground and remained there until a trainer reached the mound to examine him. The right-hander stood up and after a brief discussion walked to the visiting clubhouse on his own.
Evan Longoria homered leading off the fourth against Oswalt. Ramirez, who had a RBI double in the first, was the next batter.
Oswalt, making his fourth spring training appearance, struck out four while allowing three runs and four hits.
