Iowa Cubs
The Iowa Cubs roasted the Toledo Mud Hens (Tigers), 5-3 in 11 innings.
Terrific start tonight for Brandon Birdsell, who struck out nine over six scoreless innings. Birdsell allowed four hits and walked no one.
Trey Wingenter pitched the bottom of the tenth and was unable to keep the automatic runner from scoring, blowing the save. But he got the win when Iowa scored three runs in the top of the eleventh.
