St. Louis Cardinals rookie and Stanford grad Stephen Piscotty left Monday night's game against the Pittsburgh Pirates on a cart after being involved in a gruesome outfield collision with teammate Peter Bourjos.
Piscotty, who was playing left field, was chasing a fly ball off the bat of Pittsburgh's Josh Harrison that was headed for the indented section of the PNC Park outfield in deep left-center field.
Bourjos never stopped running and ended up making the sliding catch, but in the process caught a diving Piscotty with a knee to the left side of his head.
An initial scan came back negative. Cardinals manager Mike Matheny indicated that while Piscotty is sure to be very sore, it appears there should be no long-term damage.
