COOS BAY — After Alexz Elletson hauled in the go-ahead touchdown pass from Brogan Oswald, who added a two-point conversion run with 52 seconds left in the game Friday, it looked like an emotional win over Marist was all but wrapped up for Marshfield barring a complete collapse.

And so it was.

While staring at a seven-point deficit with 40 ticks left after the ensuing kickoff, visiting Marist proceeded to score 13 unanswered points on two passing plays — both good for 50-plus yards.

The first came on a 55-yard connection from quarterback Ryan Bell to Andrew Hughes. Before Bell stepped up and put his entire heart, soul and career into the throw, he first eluded one tackler and broke away from a collapsing pocket. He found Hughes open on a long corner route.

A Doug Flutie Hail Mary? Not quite.

“It’s exactly how we drew it up,” a teary-eyed Bell said afterward. “I was looking for someone out there and thought he might be open. I looked right, and there he was.

“This is the biggest moment of my high school career.”

With the sizable crowd at Pete Susick Stadium now reduced to a whisper, Marshfield took the field with :29 on the clock and the score tied at 20-20. A play later, Marist had the ball again. Cornerback Mitchel Wilson picked off Oswald at the Marist 40-yard line with 23 seconds remaining, sending the Spartans offense back onto the field.

Two plays later, Marist had the game. With 12 ticks left, Bell pulled another rabbit out of his helmet  — this time a 53-yard touchdown pass on a jailbreak screen to tailback Bryson Black, who shook two tacklers; fought through another then led a convoy of offensive linemen — and the entire Marist sideline, which was now sprinting toward him — into the end zone.

The scoreboard read 26-20, and the clock struck four zeros as he crossed the goal line.

“We were just trying to get some quick yards and maybe set up for a long field goal,” Marist coach Rory Rosenbach said. “We knew they were going to be covering deep, so we wanted to maybe get some yards underneath.

“These kids — I never question their effort out there. They never give up, and it’s just an amazing win for them. I’m stunned.”

The game-winning play capped a stretch of 21 points scored on five plays in less than a minute.

For the Pirates (1-1), it was simply tough to grasp.

“We thought we had the game won,” said Elletson, who had three catches for 47 yards. “We were playing cover four, and that kid just made some nice moves.

“After my touchdown, I came to the sideline and coach said, ‘They have one more drive.’ And then things just fell apart.”

Marshfield took a 6-0 lead in the nonleague bout with a 24-yard touchdown strike from Oswald to Cameron Winfrey on a fourth-and-nine play during the first quarter.

The Spartans (1-1) answered with 13 straight points to go up by seven at the half. Junior kicker Gabe Schepergerdes tied it at 6-6 with a pair of field goals from 26 and 37 yards out.

Marist took the lead on an 18-yard touchdown grab by Jeff Bedbury on a bubble screen. It was one of three touchdown passes on the night for Bell, who completed 15 of 28 for 241 yards.

“They were stopping our run, but we knew we could pass on them,” Rosenbach said. “They had a tough defense though.”

Marshfield forced four turnovers with fumble recoveries by Elletson and Jesse McClintock; and picks by Bo Cutting and Justin Kirk.

The Pirates held Marist to 127 yards on the ground but could only muster 22 net yards themselves. Senior fullback/defensive lineman Jesse Fox led with 27.

“Offense, defense — no one played well tonight,” Fox said. “Once we get back to practice and watch film, we’ll get over it.”

Oswald went 8-for-17 with 150 yards, two interceptions and three touchdown passes, including one to Jordan Shepherd in the third quarter to make it 13-12. Oswald, a dual-threat senior, gained 90 yards rushing but ended with minus 16 — due in large part to seven sacks.

“We need to get in better shape and play a complete game,” Marshfield coach Kent Wigle said. “If you learn from a loss like this, it’s not truly a loss. But if you don’t learn from it, then it’s a big loss. So if we bounce back and play with some effort — we didn’t really play with very much effort tonight — better things will happen.”
