The Montgomery Biscuits had one more rally in their hip pocket than the Chattanooga Lookouts did Monday night.
In a back-and-forth series opener at AT&T Field, the Biscuits came away a 5-4 victory in 10 innings on a bases loaded walk to Hector Guevara, who is still looking for his first Southern League hit.
Lookouts reliver Luis Vazquez (3-3), who has had battles with his control during the season, walked three in his lone inning of work Monday.
Montgomery's standout closer, C.J. Riefenhauser, earned his fourth win without a loss and lowered his league best ERA below 0.50.
Having rallied for a second time, Chattanooga came within an out of putting the Biscuits away in the top of the ninth. But an RBI triple from lBiscuits leadoff man Kevin Kiermaier pushed across the tying run. Hector Nelo, having blown the save, stranded him at third.
The Lookouts had taken a 4-3 lead in the eighth on a two-out hit from Angelo Songco, chasing home Bobby Coyle, who had also singled.
The first Lookout lead of the night took place in the third, on a two-out, two-run single from J.T. Wise. But Wise was thrown out at second to end that inning, and the Lookouts would not threaten again until the eighth.
