Christian Villanueva doubled home John Andreoli with the go-ahead run in the 13th inning of the Tennessee Smokies' 4-3 victory over the Biscuits on Tuesday.
Andreoli hit a one-out single, went to third on a Justin Bour single and strolled home when Villanueva doubled over center fielder Kevin Kiermaier's head.
The Biscuits rallied from a 3-0 deficit in the eighth and ninth to force extra innings. Both rallies started with two outs.
In the eighth, Todd Glaesmann singled and Hector Guevara walked before Keith Castillo hit a two-run double. In the ninth, Kiermaier walked, went to second on wild pitch and scored on an error.
