Seagoe’s strong second half helped to seal full points from the derby date with Markethill Swifts.
Aaron Black broke the deadlock off Harry Proctor’s cross.
Stuart Corkin slotted home a penalty after the interval before Alan Humphries’ late finish.
“Bobby Sturgeon scored but half-time came at a bad time,” said Markethill Swifts’ David Andrews. “After not playing since November, our lack of sharpness told a tale.”
