Dillon Stewart stole the show on the second day of boys golf regionals around the state on Tuesday.
The Fossil Ridge senior, who finished second at the Class 5A state state championship last season, shot a 9-under 63 to win the Class 5A Northern Regional, held at Murphy Creek Golf Course in Aurora.
His performance helped the Sabercats win the regional by 11 strokes, as they finished at 6-under as a team. Lakewood (+5) was second.
Stewart wasn't the only one under par at that regional, though: Lakewood's Ryan Liao and Cherokee Trail's Beam Boonta each were 4-under, and Stewart's Fossil Ridge teammate Owen Cornmesser was 1-under.
Elsewhere, in 4A Region 4, Montrose teammates Jordan Jennings and Micah Stangebye battled for the individual regional crown after both finished at 3-under through their round. Stangebye won in a seven-hole playoff.
Montrose, the defending 4A champions, also won the region at 2-under. Mullen was second at 1-over.
In the loaded 3A Region 2, Holy Family's Jacob Mason won the event by finishing at 4-under, two strokes ahead of defending 3A champion Davis Long of Peak to Peak.
"When you are trying to qualify for something as big as the state championship, its always in the back of your mind that you could be close to the cutline," Mason told HFAthletics.com. "There is always that chance of putting more pressure on yourself, but I like the pressure and I think our team lived up to it today."
Prospect Ridge Academy's Walker Franklin, last year's runner-up, finished in a tie for third with Kent Denver's Jackson Klutznick at 1-under. Klutznick finished in a tie for fourth at state last season.
Kent Denver, last year's runner-up as a team, won the event. Holy Family placed second. Peak to Peak, the defending champions who beat Kent in a playoff last season, was third.
At 3A Region 1, La Junta's Cody Schrock was the individual champion at 1-under. Lutheran's Westin Pals (+1) was second.
Colorado Academy won the region by shooting 16-over. La Junta (+20) was second.
In 4A Region 1, Cornado's Andrew Merz finished first at 6-over. Discovery Canyon's Scott Ieveque was second at 9-over.
Coronado (+39) also won the team championship. Lewis-Palmer (+41) was second.
Boys golf regionals conclude on Wednesday with two more events.
