That's the Indians' 28th come-from-behind win and 15th in their final at-bat.
The Indians remain one game back of first-place Detroit in the A-L Central.
Jason Michaels opened the eleven with a base hit off rookie Dewon Day that he turned into a double by beating Jermaine Dye's throw from right. Garko followed with a broken-bat bloop just over shortstop Juan Uribe's outstretched glove. Day is 0-and-1 with the loss.
Rafael Betancourt pitched a perfect eleventh for the win. He's 2-and-0.
Garko's two-run homer in the ninth off All-Star closer Bobby Jenks tied it 5-5 for the Indians. Jenks suffered his fifth blown save.
