HOUSTON -- Home-plate umpire Alan Porter left Sunday's game between the Astros and Pirates at Minute Maid Park in the sixth inning after being hit on top of the head on the backswing of a Carlos Lee swing and miss.
Porter stayed on his feet and was tended to by Astros head athletic trainer Nate Lucero and assistant athletic trainer Rex Jones before being helped off the field. He received five stitches on his head due to a laceration caused by the bat.
"You never want to see anybody get hurt out there, regardless if it's the other team or the umpire or our team," said Astros third baseman Chris Johnson.
A three-man umpiring crew was used for the remainder of the game, with Hunter Wendelstedt moving from second base to home plate.
The game was delayed for several minutes while Porter was helped off the field and Wendelstedt put on the proper equipment to work behind plate. Jerry Lane, the crew chief, and David Rackley were also working the game.
