Yarmouth endured a wild third period to knock off Cheverus 4-3 in a boys’ hockey game Thursday night at Troubh Ice Arena.

Yarmouth (4-0), ranked No. 1 in Class B South, held a 1-0 lead through two periods. Then the teams combined for six goals in the third period in a span of less than nine minutes.

Cheverus (2-2), ranked second in Class A South, outshot Yarmouth 19-9 in the third, but Yarmouth’s Walter Conrad scored the winning goal with 2:54 remaining.

“(Cheverus) is a talented offensive team and we knew they were going to come at us,” said Yarmouth Coach David St. Pierre.

Bill Jacobs took advantage of a two-on-one opportunity early in the third, banking a shot off the post to give Yarmouth a 2-0 cushion at 3:14.

The way the game had been going, it seemed like Jacobs’ goal could be the winner. Not even close.

Less than two minutes later, Sean Walsh scored a power-play goal for Cheverus (2-2). Just over one minute after that, Jesse Cyr-Brophy tied the game 2-2 with 8:32 remaining.

It took only 20 seconds for Yarmouth to regain the lead, on an unassisted goal by Patrick Grant.

There would be a scoring drought for almost three minutes until Luke Trickey tied the game again.

With exactly five minutes remaining, Cheverus was penalized for illegal contact to the head and unsportsmanlike conduct, yielding a two-minute, five-on-three opportunity for Yarmouth.

“I told the kids to stay up on that Conrad guy,” said Cheverus Coach Dan Lucas.

Cheverus would kill the power play, but Yarmouth responded just six seconds after it ended, Conrad took a pass from Grant and buried it for the winner.

“I think I actually missed two shots … before that (goal) so Pat was lucky enough to feed me a third time and I put it on net and it went in,” said Conrad.

“(A Cheverus) player came out of the box and came to pressure me and one of their guys who was in the zone also pinched and Walt had the slot so I just slid it over to him,” said Grant, who finished with a goal and two assists.

Cheverus took the loss despite holding a 35-20 shot advantage. The Stags had too many shots that hit Yarmouth goalie Dan Latham’s chest, an issue Lucas made a point of to his team before the third period.

“I think we were probably guilty of making the goalie look pretty good,” said Lucas.

Yarmouth was able to overcome a bad night on the power play. The Clippers came up empty on all four opportunities, getting just five shots – four of which came on the late five on three.

“I wanted to get more pucks to the net (on the power play). I thought we didn’t shoot when we had chances to shoot,” said St. Pierre.

The lone goal from the first two periods was scored in the first by Anders Newberg on a nice dish by Grant.

It was a big win for Yarmouth over a top-notch Class A hockey program.

“We felt we were the underdogs tonight,” said Conrad. “The only way we were going to win out there was to outwork (Cheverus). I’m so proud of the boys in that locker room because we really did work every shift and I think it showed.”
