Walker isn't the answer in SF. They need to get a closer, and they need to get one fast if they want to have any chance to win this year in SF.
Beane has always showed a tendency to pass the closer torch as soon as he can get decent value for the current closer. Given the A's current situation, Beane will be shopping Dotel around the league before the trade deadline in a few months. There are plenty of teams that could use a pitcher like Dotel, and so there won't be any shortage of buyers.
I'll say it again. Street's your guy.
