How did I do on this trade? Zobrist for Holliday?

Good move, not a good idea for the other guy to bail on Holliday right now, especially when you've already made it through this far with him. Considering his talent level and the guys he plays with in the lineup (Pujols, Ludwick, Rasmus), it should be hard for him not to produce. I'd stick it out with him, especially when you didn't give up anything too special in the process of getting him. As you said, you're getting Rollins back soon, and as for Bautista, one thing is he has cooled down significantly, and the other thing is that he's never been a good second-half player, so now is a good time to start jumping off the bandwagon if you haven't already.
