I know I'm in the minority here, but I liked the bunt. He's been ice cold and facing a lefty. You bunt for a hit, but at minimum, you get the winning run to second. Not to mention, you've got a pitcher who's juat come in, coming off a slippery mound, who has to spin to make the play. I'm a lefty and I pitched a bit in my high school days. That is not an easy play, especially with the runner blocking your view.
So worst case scenario, you now need one hit to go ahead instead of two. If the manager is gonna send him up there, which he shouldn't have, this was not a bad play at all.
