Astoria's Jenna Rudolph, No. 5, fights for possession with Seaside's Lizzy Barnes, No. 4, during their soccer game at CMH Field Thursday.

Their possible Cowapa League championship next week? Yes, that will be big for the Seaside boys soccer program.

But two wins over Astoria in the same season? Now that is something the Gulls will hang their hat on.

And it doesn’t happen very often.

Seaside’s 3-1 win over the Fishermen Thursday night, Oct. 15, at CMH Field (their first official visit to Astoria’s new stadium) marked the first time since 2010 that the Gulls made a clean sweep of Astoria.

Before that, you have to go back to 1998 to find the last time the Gulls swept the season series with the Fishermen.

With the exception of a few moments in the second half, Seaside was in command from start to finish in Thursday’s game, unlike the Gulls’ last meeting with Astoria, in which Seaside had to rally from a 1-0 deficit to win, 2-1.

“We had better discipline with the ball this time, better movement with the ball, and our touch with the ball was better,” Seaside coach John Chapman said. “As the season goes on, you expect that continuity to grow. We definitely had good, solid continuity tonight.”

And all it took was a 53-second span early in the first half.

Nine minutes, 59 seconds into the contest, Seaside’s William Garvin sent a short crossing pass from the right side near the end line, and Hunter Thompson knocked in the short-range shot for the first score.

Seaside fans did not have to wait long for the next one.

In the 10th minute, the Astoria defense failed to clear a ball, and Thompson made them pay, scoring from 15 yards out for a 2-0 lead.

The Fishermen managed four shots on goal in the first half, but nothing that threatened to get past Seaside goalkeeper Jarrett Coughlin.

“We got pressure on the ball early tonight, which put (the Fishermen) behind the eight ball,” Chapman said. “Coughlin had a great game in goal. He was solid back there and made some nice saves on the few attempts that Astoria had. And our defensive line was just solid.”

Seaside’s third goal of the first half basically put the game on ice, as Garvin gained control of a ball near midfield, raced down the right sideline and scored past Astoria keeper Elijah Hirsch.

“We were looking for that third goal, right before the half,” Chapman said. “And Garvin’s been on fire all week. His running and his speed came just at the right time, and was a little too much for the back two (defenders) for Astoria.”

Astoria’s offense found a rhythm in the second half.

The first two shots on goal from Rafael Alcantar were saved by Coughlin, but Alcantar’s third shot found the upper part of the net, from nearly 40 yards out.

The Fishermen limited Seaside to just two shots on goal in the second half.

“Astoria came back with some good spirit near the end of the game, when we were starting to sub players,” Chapman said. “And the goal that they scored, they took advantage of some sloppy play by us. And it was a beautiful shot (by Alcantar), too.”

Seaside 1, Astoria 0

Seaside won a defensive girls soccer Clatsop Clash Thursday night at CMH Field, as the Gulls scored early in the second half, then relied on their defense to do the rest in a 1-0 win over Astoria.

“We knew we were going to be battling a resilient Astoria team that was emotionally amped,” Seaside coach Matt Johnson said. “The girls were excited for the game and fed off the energy of the boys’ win earlier in the evening.”

Astoria coach Sarah von Colditz said, “The thing with these games is it usually comes down to one goal. The team that gets on the board first has the advantage. That team was not us.”

She added, “As I’ve always said, it’s a totally different game when these two teams are together. Nerves run high. Very high.”

Neither team could generate much offense.

Seaside finished with 10 shots on goal for the game, to just two for the Lady Fish.

Astoria goalkeeper Lexi Law was able to stop the first three Seaside attempts, broke up a breakaway in the 33rd minute, then grabbed two long shots by Seaside’s Whitney Westerholm in the final four minutes of the first half.

But Law was not able to stop Seaside’s first shot on goal of the second half.

Taking a pass up the middle from Westerholm, Seaside’s Sophia Trevino dribbled past a pair of defenders, then placed a shot into the far right side of the net, just out of Law’s reach for the game’s only goal, with 36:50 left.

“Whitney has a knack for assists,” Johnson said. “She is so good at setting up her teammates for scoring opportunities.”

Law made saves on Seaside’s other three shots in the second half, two by Trevino and another attempt by Brenda Lopez.

Jenna Rudolph had Astoria’s only serious shot attempt of the second half, but the ball sailed wide left of the net.

“We played our game, but couldn’t put the ball in the back of the net,” von Colditz said. “You have to shoot to score, and unfortunately we did not have numbers up when we needed it.”

Johnson said, “We looked good when we settled the ball and played our passing game, but Astoria was winning most of the 50-50 balls. During halftime, the team talked about what was working and what needed to be fixed.

“I loved the dialogue the girls had during the halftime break. Everything was ‘we,’ not ‘I.’ We need to go hard to the ball, we need to stay composed, we need to pass to the open girls, we need to have patience on defense … they were all on the same page.”

Von Colditz was equally pleased with her team’s effort.

“I felt as though the teams were evenly matched,” she said. “Seaside plays more long balls, while I prefer we play the ball on the ground with what I call ‘pretty soccer.’

“Our back line was strong, solid and backed each other up,” she added. “Lexi Law had several amazing saves. Jen Rudolph won the center several times with her flick on headers.”

While Seaside’s Jesse Trott picked up the win in goal, it turned out to be a good week after all for Law.

The sophomore goalkeeper missed the last 20 minutes of Tuesday’s game against Scappoose after picking up a red card, but then had the red card overturned before Thursday’s match. She was also named Athlete of the Week by station KOIN 6 in Portland (will air Oct. 30).
