Adam Dunn chose us over the Dodgers, which is a compliment. He brings much needed power, and can't possibly strike out more than some of the cupcakes.
I suspect part of Dunn's decision hinged on his not having to play either first base or the outfield, as he's brutal defensively. I watched him play RF during the Sox recent trip to AT&T Park--an endeavor that saw him fail to run down a fly-ball hit into the RCF gap by Buster Posey and crash into a teammate who had already waved him off, resulting in a two-run error during a disastrous seven-run inning.
Dunn's home run in his first at-bat reminded me of when Frank Thomas joined the A's in 2006. I doubt Dunn makes the kind of impact that the Big Hurt did, but he might help the A's hang on to their WC spot.

You are probably right. The A's have been a streaky team for a long time. They change out so many bits and pieces every year that there is never time for a real 'core' to form, a core that can steady the team when they start to lose, or keep them level when they start to win. So they need boosts and "momentum", particularly this season when a good third of the team knows they are either playing for a ring or a to get a better FA contract, and won't be in an A's uniform next season.
Dunn comes in, hits a homer in the cavernous Coliseum, and the A's have a solid game. That kind of stuff builds faith and restores order. Now if they sweep the Mariners, they ought to rattle off a few series. They have 7 games against the bottom dwelling Rangers, 4 against the almost bottom dwelling White Sox, 3 against the bottom dwelling Phillies, and three against Houston.
The only real challenges (on paper) are the remaining 5 games against Seattle, and the three against LAA at home.
The Angels have a super easy schedule in September, with the only real challenges coming from Seattle and Oakland.
So it looks like Seattle will be the kingmaker in September, and interestingly enough, if the Mariners are only two games out from the second WC spot. If they are able to bloody Oakland and LAA, three of the five playoff teams might come from the AL West.
