Kyle Quinlan made sure the McMaster Marauders stayed perfect.
The fifth-year quarterback was 25-for-36 passing for 340 yards and two touchdowns and also ran in another score as No. 1 McMaster defeated the No. 5 Queen's Gaels 33-20 in Canadian university football Saturday.
Robert Babic was Quinlan's top target on the day, catching nine balls for 104 yards and a TD, while Ben O'Connor caught three passes for 62 yards and a touchdown for McMaster (4-0).
Brad Fochesato caught four passes for 92 yards, while Declan Cross rushed for 132 yards on 17 carriers for the defending Vanier Cup champions.
"This was a big win, but the locker-room is not satisfied with it. We had troubles in the second half and that's frustrating," said Quinlan. "The end result was good, Queen's is a real tough squad and winning gives us an inside track, but we have to get back to work."
Queen's quarterback Billy McPhee was 29-of-46 for 320 yards and touchdown for the Gaels (3-1).
Justin Chapdelaine had seven catches for 70 yards and a TD, Giovanni Aprile caught six passes for 103 yards and Ryan Granberg rushed 20 times for 103 yards and touchdown.
Elsewhere in the CIS it was: No. 2 Calgary 62, UBC 7; No. 3 Montreal 15, No. 10 Sherbrooke 6; No. 6 Western 46, Windsor 23; No. 8 Manitoba 51, Alberta 38; Acadia 26, Saint Mary's 10; Mount Allison 36, St. FX 19; Guelph 31, Toronto 29; Bishop's 38, Concordia 30; Laurier 35, Ottawa 27; and Waterloo 23, York 22.
At Hamilton, Tyler Crapigna was 4-for-4 on field goals for McMaster, which led 26-3 at halftime.
Quinlan hit Babic on a 35-yard pass to open the scoring early in the first quarter. After Queen's kicker Dillon Wamsley connected from 42 yards out to make it 7-3, Crapigna four straight field goals to make it 19-3.
O'Connor then hauled in a 50-yard pass from Quinlan with 39 seconds left in the half to give the Marauders a 19-point edge heading to the locker-room.
Quinlan scored on a six-yard run in the third quarter before Granberg rushed from two yards for the Gaels out to make it 33-10.
After a Queen's rouge in the fourth, Chapdelaine and McPhee hooked up on a nine-yard TD in the fourth before the Gaels rounded out the scoring after McMaster conceded a team safety with three seconds left on the clock in the fourth.
