BRUNSWICK, Maine -- Bowdoin won the first three completed singles matches to earn a 5-1 victory against Trinity (Texas) in the regional finals of the NCAA Division III tournament on Sunday.

With the victory, the Polar Bears (15-7) advanced to the national quarterfinals for the first time since 2002.

Trinity ended its season with a record of 21-8.

The Tigers and Polar Bears split a pair of early doubles matches, with Jordan Mayer and Greg Haugen earning an 8-5 win at No. 2 doubles to give Trinity the early edge. Bowdoin answered at No. 3 moments later when Casey Grindon and Chris Lord completed a 8-6 victory to even the contest.

At No. 1 doubles, Bowdoin's Samuel King and Oscar Pena dueled Max Frey and Erick DelaFuente into a tiebreak before the Polar Bears eventually claimed a 9-8 win at a 2-1 advantage heading into singles play.

Bowdoin seized the momentum from there, as Lord dispatched Haugen 7-5, 6-1 at No. 3 singles and Pena finished off Frey 7-6, 6-0 at No. 1. Three matches were all poised to be the clincher for Bowdoin, but it was Grindon who earned the clinching point, watching a return from Charlie Curtis sail long at No. 4 singles to seal the match.

King was about to serve match point for Bowdoin at No. 2 and Bragg was two points away at No. 5 when Grindon claimed his contest. Aaron Skinner of Trinity led Kyle Wolstencroft 6-2, 2-3 in the final remaining match at No. 6.
