BOYS SOCCEROneonta 5, Owego 3
After its three-goal lead was erased, Oneonta High scored twice in the last 7 ½ minutes to win their season-opener at Southern Tier Athletic Conference rival Owego.
Junior Theo Malone scored with 7:35 remaining to give the Yellowjackets a 4-3 lead. Malone received a throughball from Peter Paluch, touched it once before beating on-rushing Owego goalie David Ackerman to the right post.
“It was quick,” OHS coach Alex Brannan said of Malone’s second goal of the game. “He ran a long way, touched it once and the second touch was inside the post.”
With 45 seconds to play, senior Zach Joseph finished a pass from Ian Oliver to give OHS a two-goal cushion.
The Yellowjackets, who won their first STAC title since 1985 last season, took a 3-0 lead in the first half.
Malone scored eight minutes into play off an assist from Oliver.
Then Joseph set up OHS’ next two goals on corner kicks. First, Paul Bischoff headed home a service to make it 2-0 with 19:14 left in the half and then Oliver volleyed in a Joseph corner 1:28 before halftime to make it 3-0.
But Zachary Riegel scored 19 seconds later for Owego to make it 3-1.
“If you were at the game, it was just up-and-down, up-and-down,” Brannan said.
Will Delaney and Adam Blackwell scored second-half goals to tie the score for Owego.
“I think we were saying, ‘Oh, it’s 3-0, look at us,’” Brannan said. “I thought, hey, it’s not 3-0, anymore, it’s 3-1. They get another one and all of a sudden it’s tied. You can’t let your guard for a minute.”
