Looked like he was slowing up at 2nd, but why?
In general, MLB players are bums
and don't play the game hard when they don't have to.
That's why I love to hear that Harper always runs out everything, etc. In lower levels of baseball, playing the game 100% for 9 innings is standard. In MLB, not so.
I really don't understand that play because it was hit in the gap with 2 outs. Just go hard until the play ends.
