LAFAYETTE — Growing pains were expected. Somehow, they’ve mostly been avoided.

The Peak to Peak girls basketball team — yes, the same Pumas that graduated nearly the entire starting lineup from last season — improved to 5-1 Tuesday with an impressive 50-37 home win against Pinnacle.

The Pumas start two freshmen and only two players, senior point guard Khadijah Sayyid and junior Linnea Danielson, have big-time varsity experience. Danielson has been out since the opener because of a knee injury.

Seemingly a shell of last season’s 18-5 squad, the Pumas have churned out five straight underclassmen-heavy wins after an opening loss to Northridge.

“It’s been really good,” Peak to Peak coach Chad Rathbun said. “They’ve learned quick and it was a big win tonight. Especially with all those freshmen out there.”

The Pumas put away the Class 3A non-league contest with a 14-0 burst to start the fourth quarter after letting Pinnacle (1-3) hang around for three quarters. Sayyid had endured an off night from the floor to that point, but drilled her first four shots of the fourth and finished with a team-best 15 points.

“We calmed down and got more disciplined,” Sayyid said. “We didn’t let their aggressive defense get to us.”

Sophomore Annette Warner, a “C” Team player last season, made a significant impact off the bench. She grabbed a game-high 13 rebounds and chipped in seven points.

“I just attack the basket after they shoot,” Warner said. “I was ready. I was really pumped up for this game.”

The balanced Pumas also got key contributions from Ivy Devries (11 points) and freshman starter Katharine Kia, who added eight points and nine boards.

Twelve first-half fouls and a solid performance from Pinnacle point guard Alexus Ramirez (game-best 18 points) allowed the Timberwolves to stay within striking distance before Sayyid’s late barrage.

“She’ll get hot,” Rathbun said. “I’m confident in her ability to score. If she gets into foul trouble, she can’t get into a rhythm, and that’s what was happening early.”

Sayyid was more comfortable than she thought while on the bench and leaving the reins to her youthful teammates.

“I didn’t think we’d be doing as well as we are right now,” she said. “We definitely have room to grow, but we’re doing a lot better than I thought we would.”
