Rehabbing major-league pitcher Jason Isringhausen said he felt "fine" after his final appearance with the Biscuits on Monday.
Isringhausen allowed a run on two hits and a walk and threw 29 pitches (15 for strikes). He stood to be the losing pitcher before Montgomery rallied in the eighth inning to take the lead.
In the ninth, the Biscuits notched their fourth blown save of the year and rallied for a 6-5 win over the Suns.
"I'm nine days into my rehab and I just have to go on," Isringhausen said. "I'm not worried about results right now. I'm just doing what it takes to get ready."
Isringhausen will move on to Triple-A Durham this week. His schedule calls for a two-inning appearance Thursday.
On Monday, he got a broken-bat groundout from the first hitter he faced before running into trouble. Bryan Peterson tripled to right -- he sneaked a 2-2 inside curveball just inside the first-base bag -- and scored on a Scott Cousins flyout. Lee Mitchell doubled to left and Kevin Randel walked before a flyout ended it.
