Also chipping in was Adam Sylva who grabbed 2 for 20 and Henry Cooper, who took 2 for 30.
For Boys' High, Sam Walker was the only one to show any real resistance as he top-scored for his team with 34.
Boys' High representative Russell Smith said his team was made to pay for their mistakes.
"[Lezar] capitalised on his chance and hit a fair few boundaries along the way. He was dropped on 0 and twice more ... we just didn't field particularly well," Smith concluded.
He added that the Boys' High pitch played better on the weekend compared to during their round one win over Kaipara Flats.
Smith felt both sides could have scored more runs if they had have made better decisions at times.
