Vlad Jr. Hits 103 MPH Screamer off Pitcher’s Head

D-backs prospect Tyler Mark walked off under his own power after being struck in the head by a line drive off the bat of Vladimir Guerrero Jr. in the third inning of an Arizona Fall League game on Wednesday night at Salt River Fields.

Watch below: 

The pitcher delivered an 80-mph slider that Guerrero lined back up the middle with an exit velocity of 103.24 mph, per Statcast™.

The ball ricocheted off Mark into the third-base dugout for a ground-rule double. Dude’s lucky he didn’t lose an eye.
