Just when you thought this crazy week at Petco Park San Diego couldn’t get any crazier, the craziest thing possible happens.
The Padres defeated the Giants 7-6 in 10 innings on Saturday night, scoring the winning run when closer Santiago Casilla lost his balance on the hill and was called for a balk.
Yes, the ultra-rare and always embarrassing*walk-off balk literally tripped up the first-place Giants and set off another celebration at Petco Park.
What an ending.

According to Harvard Sports Analysis, this is the 20th walk-off balk in MLB history. That makes it a true rarity, although the most recent occurrence only came last season when the Dodgers defeated the Rangers 1-0 on a Keone Kela balk.

It was a pretty fitting ending to Saturday’s game considering how neither team seemed all that interested in taking control. San Diego started by blowing a five-run lead. Once San Francisco tied it in the sixth inning, it remained that way until the 10th. Then Buster Posey gave the Giants a short-lived lead with his first career extra-inning home run, only for Casilla to falter in the bottom half.

As noted, it’s also the latest memorable moment in a fun*week at Petco Park. That included all of the All-Star festivities and also the cheesiest catch of the season.*Needless to say, they’ll be talking about this week for a long time in San Diego.
