MERIDIAN — By now, Rocky Mountain boys basketball coach Dane Roy is comfortable allowing point guard John Sherle to follow his gut instinct.

So after calling a timeout with 15 seconds left on the clock and his team trailing by one point, Roy gave the junior his blessing to make something happen.

Sherle let intuition lead, driving the length of the court for the game-winning layup in a 50-49 victory at Mountain View on Thursday night.

It was the final game of the 5A Southern Idaho Conference regular season for both teams, and it gave the Grizzlies (17-3, 15-3) the season sweep of the Mavericks (16-4, 14-4) and the No. 2 seed in the upcoming district tournament.

"I trust John so much as my point guard. It's wonderful to have him on the court," Roy said. "We run a play where he needs to get a high pick and then he goes to work. I trust John to make the play and he typically does. … It wasn't a surprise for us. We knew he was going to get a good shot, it was just a matter of whether or not it was going to go in."

Sherle finished with a team-best 17 points — including six of Rocky's 12 fourth-quarter points — and three assists.

"I had it in my mind I was going to the hoop the whole way," Sherle said. "I needed to score and I knew I was scoring."

Rocky Mountain has won eight games in a row heading into the district tournament, which begins Tuesday at Capital and Borah high schools. The Grizzlies are arguably the hottest team going in after ending top-ranked Borah's 40-game winning streak last week followed by Thursday's clutch victory against the Mavericks.

"They are starting to figure out how to win. It's something you can't really teach," Roy said. "It just comes with game experience, and we've got some kids that play a lot of basketball."

In a game that featured 13 lead changes and six ties, Mountain View looked equally sharp. The Mavericks went ahead 49-48 with about 16 seconds left in the fourth quarter on a 3-pointer by Tanner Percifield.

Percifield then had a chance to negate Sherle's game-winner, but his deep 3 at the buzzer bounced off the back of the rim.

"I thought Tanner was going to come down and make it," Roy said. "I love Tanner. He's such a good player. That freaked me out a little bit too."
