What makes the photo on a baseball card great can vary. Sometimes, a great photo showcases a sharp photo of a great hitter, mid-swing. Especially from a unique angle.
Maybe the player's shown in the field or the base paths.
There are many reasons to pick a great photo, but I think the following image might be the best.
How often do you see a pitcher leaping over someone on the base paths?
There's a little more to this photo than meets the eye, however. He wasn't covering second for some strange double play move. On May 7, Stephen Drew hit a ball into the gap between first and second, and Patterson (playing second for the Padres) managed to field the ball. Moseley was covering first, as all pitchers should do on ground balls hit to the right side. Patterson made an errant throw to first, an extremely high toss that ended up around the backstop. Moseley got some serious air trying to catch the ball, and did the strange splits-like gymnastics move you see above as he watched the ball sail on by. You can see the play here. It's the last video highlight available for the game ("Roberts scores on error").
Moseley had a tough year as a starter for the Padres, going 3-10 on the season, despite a respectable 3.30 ERA.
It's a rare moment caught on film - and cardboard - that may make this the best photo in 2011 Topps.
