Video: Dustin Johnson pounds golf balls into McCovey cove

SAN FRANCISCO — Dustin Johnson threw out the first pitch at Wednesday's Giants-Astros game (that would also be the same one Matt Cain pitched a perfect game at), but before he took the mound in front of a packed house, he warmed up in front of about 50 people earlier in the day by hitting drives at AT&T Park into McCovey Cove.

TaylorMade put on an event to showcase Johnson's length off the tee and, needless to say, he didn't disappoint. Johnson pumped a number of drives over 330 yards from home plate, including a 335 yard bomb that ended up being his longest of the day.
