MANCHESTER, N.H. – Chris Tsonis converted a penalty kick with 13:42 remaining in regulation as second-seeded Southern New Hampshire edged Merrimack 1-0 in the second round of the NCAA tournament at Larkin Field. The Penmen improved to 18-3, while the Warriors' season comes to a close at 15-4-2 overall.

Southern New Hampshire advanced to the third round to face fourth-seeded UMass-Lowell. The Penmen topped the River Hawks twice this season, a 3-0 win on Oct. 17 and a 2-0 win in the Northeast-10 semifinals on Nov. 2.

Southern New Hampshire was awarded a penalty kick when Tsonis was hauled down in the penalty area by a Warrior defender. Tsonis converted the penalty kick for his team-high 15th goal of the season.

Merrimack, which was playing a man down following a red card in the 63rd minute, nearly came up with the equalizer with just under eight minutes to play. Off a long throw in from the right side of the field, Olof Lindhe attempted to head the ball in inside the far left post, but Penmen keeper Dom DiMaggio made a diving save to keep the Warriors off the board.

DiMaggio turned aside two shots en route to his 11th shutout of the season, while the Penmen were also credited with a team save as a Penmen defender swept away a Merrimack attempt late in the first half. Warrior keeper Jose Silva made seven saves as SNHU outshot Merrimack 16-11. The hosts also had five of the game's six corner kicks.
