BROOKVILLE, N.Y. -- Junior midfielder Andrew Chadderdon scored the game-winning goal 1:02 into overtime to give third-ranked and third-seeded Le Moyne a 9-8 overtime victory against fifth-ranked and second-seeded LIU Post in the first round of the NCAA Division II tournament Saturday at Hickox Field.

The Dolphins advance to the NCAA semifinals for the 11th time in the past 12 years. For the first time in the 11 appearances, the Dolphins will be on the road, visiting fourth-ranked and top-seeded Adelphi.

Le Moyne won an overtime game for the first time since March 10, 2007, at Mercyhurst and improved to 7-6 all time in overtime games (lost the previous three).

The Dolphins opened the game's scoring just 2:43 into the contest as Mike Jenkins fired his 13th goal of the season into the back of the net.

Following a Le Moyne slashing penalty, the Pioneers took advantage of the extra man as Connor Drost finished off a feed from Ryan Slane with 9:08 remaining in the opening quarter.

The Dolphins regained the lead with 5:56 left in the first half as Joe Corapi registered his 23rd goal of the campaign.

LIU Post, which defeated the Dolphins in the 2009 and '10 national championship games, scored the only two goals in the second quarter. Slane knotted the score at 2 with his 30th goal with 11:01 left in the quarter. The Pioneers took a 3-2 lead into the intermission as East Coast Conference Rookie of the Year Matty Beccaris tallied his 35th goal with 56 seconds to go.

Following a two-hour lightning delay prior to the start of the third quarter, the teams lit up the scoreboard in the second half with 11 goals in the 30 minutes. Kevin Kelly started the scoring by picking up a rebound and dumping the ball into the back of the net to tie the score with 13:03 remaining.

A little more than two minutes later, the Pioneers regained the lead as Chris Ruhlig tallied his 19th goal after taking a pass from Drost.

Le Moyne responded with three consecutive goals to close out the quarter. Alec Westerhoff evened the score at 4 with an unassisted goal with 9:04 left. Kelly gave the Dolphins the lead with his 19th goal of the season with 6:38 to go after receiving a pass from Jenkins. The assist marked the 20th of the season for Jenkins, the third most by a Dolphins freshman and the most since Ryan Spillett established the mark of 39 in 2000. Doug Bailey closed out the quarter's scoring with his eighth tally of the year with 1:37 remaining.

LIU Post started the fourth quarter's scoring as Anthony Berardis netted an unassisted goal 42 seconds into the stanza.

The Dolphins regained their two-goal advantage with 7:21 remaining after Max Wagner caused a turnover. Conor Regin picked up the loose ball and cleared it upfield, which led to the 15th goal of the year by Kam Bumpus.

The Pioneers answered back less than two minutes later as Drost scored after having his initial blocked by a Le Moyne defender.

Westerhoff registered his 14th goal of the campaign with 4:24 remaining to extend Le Moyne's lead back to two.

After a Le Moyne turnover out of a timeout, the Pioneers carried the ball into their offensive end before calling a timeout of their own with 1:54 remaining. Just 20 seconds after the timeout, Berardis recorded his 21st goal to pull LIU Post within 8-7. The Pioneers won the ensuing faceoff and following a pair of missed shots, Drost tied the game at 8 with 31 seconds remaining after taking a pass from Beccaris.

The Dolphins had two shots to win the game in the final seconds of regulation, but put one wide and one high.

After Aaron Cahill picked up the ground ball on the opening faceoff of the overtime period, the Dolphins called timeout. Just 25 seconds later, Chadderdon fired in his 24th goal of the season to win the game and send the Dolphins onto the NCAA semifinals.

Senior goalkeeper Jeff White made six saves between the pipes to earn his 16th win of the season and the first NCAA victory of his career. Tim Bradley made 12 saves in the loss for the Pioneers.
