The Saints' 2020 playoff run ended Friday night at Mill Valley with a 42-7 loss.
Aquinas (6-4) stopped Mill Valley twice to start the game, but the Jaguars (8-2) scored three touchdowns in the second quarter to take a 21-0 halftime lead.
"Credit Mill Valley for playing hard and having a strong game plan," said coach Randy Dreiling. "It was a difficult loss for us. I want to thank our seniors for sticking with it this season and taking this program to sub-state again." 
Aquinas began the season 4-0, including a shutout win over St. James and a third consecutive victory over Bishop Miege. While the Saints ended the regular season with three losses, they battled back to earn their seventh consecutive sub-state appearance.
"We also had a number of young guys out there this year, and that's great experience for them," said Dreiling. "Now they and all the other underclassmen have the opportunity to come back next season and make an impact."
Mill Valley, the defending Class 5A champs, defeated Aquinas for second consecutive time, the Jaguars' first such streak since the 2015 season, following last season's 34-31 sub-state overtime win over the Saints.
The Jaguars out-gained Aquinas 378-85. Aquinas had five first downs and punted eight times. 
Sophomore fullback, Sean Carroll, rushed for 63 yards. Sophomore defensive end, Sa'o Siavi'i, had nine tackles, two for a loss, and two hurries.
Junior defensive back, Dajni Brooks, intercepted Mill Valley on the fourth play of the game on 3rd and 10.
But Aquinas went three and out and, after the punt, the Jaguars started from their 44-yard line.
At the Aquinas 43-yard line, junior defensive lineman, Jalen Marshall, batted down a pass and stopped an inside run. Then Siavi'i stopped a scramble, and Mill Valley punted.
Starting from their 22-yard line, senior back, Tyron "Tank" Young gained a first down on 3rd and 5, but after a four-yard loss and unsportsmanlike penalty, Aquinas faced 2nd and 29. After a fumble and a sack, Aquinas punted to their 32-yard line.
