Catching two home run balls in one game is extremely rare, but as one fan proved, it is possible.
The first home run was an absolute blast that bounced off the left field wall and back to Pinkard. The second one came right at him, and after another attendee deflected it, Pinkard came up with the ball.
To make things even better, this was Pinkard's first-ever Astros game. That's a good enough experience to make him consider going to more in the future.
