Each year when South River field hockey Coach Katie Corcoran schedules opponents for the South River Invitational Tournament, she aims to give her players a tough early-season challenge.

The top-ranked Seahawks play an extremely difficult schedule in Anne Arundel County, but the tournament format allows Corcoran’s team to play challenging nonleague games that won’t count against its state tournament record.

This year, she succeeded in making things difficult.

South River fell behind early in the tournament final Saturday and lost, 2-1, to Baltimore power Bryn Mawr for the second consecutive year in the event.

“It helps us to see different teams,” Corcoran said. “We know the teams in our county and their styles so when we see these teams from other counties and private schools, we can see what we have to work on.”

The Martians scored twice in the first seven minutes, both times on possessions following corners, and South River suddenly found itself trying to dig out of a hole against a team with a superior defense.

Corcoran called an early timeout and the Seahawks settled into the flow of the game, but they failed to solve Bryn Mawr goalie Claire Edelman despite creating several opportunities to score.

A South River goal was disallowed midway through the first half for going in off of a player’s leg, and Seahawks forwards Kayla White and Abbey Lawrence and midfielder Alex Watson were all stopped on open shots from close range in the second half.

“We kept shooting and shooting but [Edelman] was very good and stopped a lot of our shots,” Lawrence said. “We definitely need to work on finishing, but she was good and their defense was hard to get by.”

Senior forward Brooke Cox finally got South River on the board with a goal off of a rebound with 10 minutes 35 seconds to play, but the Seahawks never really threatened Edelman and the Martians after that.

Earlier in the day, South River earned an impressive 2-1 overtime win over No. 2 Glenelg when Lawrence scored with eight seconds to play in the extra period of a semifinal matchup that pitted last season’s Anne Arundel and Howard County champions.

Bryn Mawr beat No. 9 Holy Cross, 5-0, in the second semifinal, and Glenelg beat the defending Washington Catholic Athletic Conference champion Tartans, 6-0, in the third-place game.
