Teams performing better than I envisioned
I thought the Twins would finish last in their division and I had the Dbacks in 4th in their division. Rockies were a team I thought could be a sneaky wildcard team so them playing well isn't too surprising, but them playing THIS well certainly is. They're one of the 5 best teams in MLB right now. Angels being .500 at this point makes no sense. Going into the season I saw them as a team that could sneak into the WC discussion but that fizzled quickly when the injuries struck. They have little depth as it is so any key injuries would likely torpedo them. Fact they are 1 GB of the WC and sitting at .500 right now with their ace, #2 starter, closer, and now obviously Trout out is a surprise. Still got a few more weeks without Trout but if they can stay at or around .500 in his absence that'll be amazing.
Teams doing worse than I envisioned
Really no reason for that Cubs roster to be under or at .500 at this point in the year. Giants being one of the worst teams in MLB speaks for itself and the Indians haven't really taken off in a division where you figured they'd dominate it
