CUMBERLAND — Seventh-seeded Greely got a clutch performance from backup guard Jordan Bagshaw to advance to the Western Class B quarterfinals.

Bagshaw, who sank five 3-pointers, scored a team-high 19 points to help the Rangers hold off 10th-ranked Poland, the defending regional champion, for a 64-44 victory in a boys’ basketball prelim Tuesday night.

Greely (10-9) will play second-seeded Cape Elizabeth (15-3) at 12:30 p.m. Saturday at the Portland Expo.

A year ago the Knights came out of the sixth seed to upset the top-ranked Rangers in the regional final.

Tuesday night, Greely used a hard-nosed defense and a patient offense to grab momentum nearly from the outset and send Poland home early.

“I try to get these guys to play defense first, get one stop, and come down and have a good possession,” Greely Coach Travis Seaver said. “I thought in the first half we got good possessions and we got the ball where we wanted to get it.”

The Rangers reeled off runs of 7-0 and 6-0 in the first quarter to take a 15-8 lead.

Greely hit its first four shots of the second quarter to open a 24-11 lead with 5:20 left in the first half.

“We shot well,” Seaver said. “When the ball goes through the hoop it makes the game a lot easier. Guys are up on their toes and it just makes the game easier.”

The Rangers sank 12 of 25 shots in the first half and took a 30-17 lead into the break.

“They got looks and they just knocked down every single one of them,” Poland Coach Tyler Tracy said.

Poland (8-11) managed to hit just 6 of 23 shots in the first half.

“They did a good job early of taking away what we do well, so it took us a while to get into a flow,” Tracy said. “When we finally did, we couldn’t get a stop.”

The Rangers ran into foul trouble early in the second half but it didn’t seem to slow them at all.

“The way Jordan came off the bench and started knocking down shots obviously helped,” Seaver said.

Bagshaw sank all five of his 3-point goals in the second half.

“We (also) went to (a) zone (defense) and maybe that changed things a little bit,” Seaver said.

“It protected some of our guys and it also changed the look of what we were doing defensively.”

Bagshaw hit back-to-back 3-pointers to open a 58-38 lead with 4:10 to play.

“We had good possessions but we couldn’t buy a basket,” Tracy said. “We couldn’t finish.”

John Fossett led the Knights with 19 points. Alan Young followed with 10.

Jordan Tebbs, a 6-foot-3 forward who spent most of the third quarter on the bench with four fouls, scored 10 points for Greely.

The Rangers lost twice to Cape Elizabeth in the regular season. On Jan. 31, Cape rolled to a 61-41 win at Cumberland. On Feb. 5, Cape won 61-39 on its home court.

“We’ve got a tough matchup,” Seaver said.
