Henry Blanco, the Mariners' 41-Year Old Backup Catcher, Hit a Grand Slam That Nailed a Red Sox Fan In the Knee [GIF]

Henry Blanco turns 42 on August 28th. Blanco, who had hit just 70 career home runs since making his debut with the Dodgers in 1997, smoked a Ryan Dempster pitch over the Green Monster during the 5th inning of tonight’s Mariners – Red Sox game. The blast put the Mariners up 7-1, but more importantly it hit a Bostonian in the knee.
