There is no task more difficult in sports than hitting big-league pitching. Sure, there are arguments to be made for other sports, but at times, MLB pitchers have it seem miraculous that anyone is even able to make contact.

On Sunday, Mariners pitcher Luis Castillo offered his own case for that argument.

Facing Mets third baseman José Iglesias in the fourth inning with a 1-2 count, Castillo broke out a 96 mph sinker that basically had Iglesias swinging out of his shoes. Iglesias -- who is having himself a great season -- looked completely overmatched as he swung through the inside pitch and fell to the ground.

Like, what is Iglesias even supposed to do there? The pitch looked like it was heading towards the heart of the strike zone before abruptly running inside -- 20 inches of horizontal break will do that.

Even the best hitters are bound to get embarrassed from time to time. It just happened to be Iglesias' turn on Sunday.

Fans were understandably stunned with that pitch. That's a tough strikeout to bounce back from.
