The club appears to still be interested in retaining both Wolf and Brocail, but the interest has cooled, especially with Wolf, whose contract offer, which the Astros extended earlier this season, is believed to have been pulled.
In the interest of saving payroll, it looks as though the Astros didn't want to risk having both players accept arbitration and signing for more money. The Astros have apparently pulled their offer to Wolf, which, if it was worth anything, he probably would have taken. So the Astros have pulled their ten dollar offer and are trying to get him to sign for a five and two ones...
I'll say it again, the Hampton signing was meant to replace Wolf.
