Abnormal heart rate lands Cubs pitcher Carlos Silva on disabled list

Carlos Silva was released from a Denver hospital and placed on the disabled list for a cardiac evaluation Monday, one day after an abnormal heart rate forced the Chicago Cubs pitcher to leave his start against the Colorado Rockies in the first inning.

Silva returned to Chicago and consulted with a Cubs physician, and will continue to be evaluated and undergo further tests under the care of a cardiologist at Northwestern Hospital. There is no timetable for his return, the team said.

Indians’ Santana injured

Cleveland Indians rookie catcher Carlos Santana was carted off the field at Fenway Park on Monday with his left leg in an air cast after a seventh-inning collision at the plate with Red Sox rookie Ryan Kalish.
