Oakland is playing outta this world right now. Really the only bad thing about the team is the bullpen. Oakland spent an uncharacteristically large amount of money on Jim Johnson to be the closer and the dude has sucked balls this year. Plus, they don't have anyone who can inherit a poor situation and come out unscathed. The bullpen is giving up inherited runners often - and there have been quite a few blown saves. The offense, defense and starting pitching is playing at a high level right now and more than makes up for it though. When they lose, it's 3-2 or something (fucking King Felix), but they win plenty of games 10-1. Even the 7-9 spots have been hitting well.
Also, they're oddly playing way better on the road than at home right now.
