In the first inning of today's Cardinals-Rockies game, Todd Helton caught Carpenter napping. After taking a pickoff throw he fakes the toss back to the pitcher, and tags Carpenter as he wanders off the bag.
Listen closely just before Helton applies the tag. You can hear people—presumably the St. Louis dugout—screaming at Carpenter. Recognition flickers only after it's already too late. Todd Helton is the best.
