In a game featuring an array of dazzling dunks and flashy fastbreaks, the Archbishop Riordan boys basketball team set the tone Thursday night in a 68-51 win over St. Ignatius on a comparatively mundane first three halfcourt possessions.

Zion Sensley finished through contact with an and-1 layup, Jasir Rencher bullied inside for another pair of free throws, and then John Tofi earned two more free throws.

The message was simple: make an undersized St. Ignatius front line, one missing injured 6-foot-8 senior Theo Lamb, attempt to defend the rim against Riordan’s tall wings.

Ninth-ranked Riordan (6-3) found little resistance in the Crusaders’ second straight West Catholic Athletic League rout. Riordan had defeated St. Francis 88-40 on Tuesday.

“I wanted to get in there and make them feel me,” said Rencher, who scored 12. “I felt like they disrespected us on the rankings, so I wanted to show them why we should be on top.”

Seventh-ranked St. Ignatius (9-2, 0-1) was able to stay in the game for a half because of hot 3-point shooting.

Riordan’s San Francisco rivals hit five triples in the first two quarters, and trailed only 30-23 at intermission. Steele Labagh, who made four 3-pointers, led SI with 21 points. However, the Wildcats missed several layups, much to the chagrin of head coach Jason Greenfield.

“I thought we got to the basket with ease,” Greenfield said. “We just couldn’t score over their length.”

Riordan took control after the break, outscoring St. Ignatius 21-10 in the third quarter. Sensley, who transferred back to Riordan this summer after spending the previous two seasons at Prolific Prep, scored 17 points.

“He’s back home,” Riordan coach Joe Curtin said. “It’s just great to see him in front of a crowd like this, and in front of his classmates. That’s something he’s missed for years in high school.”

Sophomore guard Andrew Hilman thrilled the packed gymnasium with a variety of crafty drives and tomahawk dunks on his way to 16 points.

In what is scary news for the rest of the WCAL, Riordan could get even bigger and athletic this season. The team is still waiting to see if 6-foot-10 Priory transfer Nas Emeneke will be ruled eligible.

No. 5 Archbishop Mitty 61, Bellarmine 41 >> Archbishop Mitty (7-4, 1-0 WCAL) easily handled Bellarmine (5-6, 0-1) as Nathan d’Abreu Noronha led the team with 18 points. Gavin Ripp pitched in 14 points and Aaron Biebel had 10 points.

No. 6 San Ramon Valley 62, No. 11 Berkeley 47 >> San Ramon Valley came back from winning the Gold Division at Damien and took down giant-slayer Berkeley, which had defeated last year’s NorCal Open Division teams Dougherty Valley and Modesto Christian earlier this season.

Luke Isaak, who hit the game-winning shot in the championship game at Damien, scored 12 of his team-high 24 points in the fourth quarter. Seamus Deely scored 11 points and Jack Moxley had 10 points.

Ollie Miller scored 19 points and Samir O’Brien scored 15 points to pace the Yellowjackets. The Wolves snapped Berkeley’s four-game winning streak.

St. Mary’s-Stockton 60, No. 5 Acalanes 49 >> Acalanes (11-4) was able to hang tough with one of NorCal’s elite teams in a possible playoff preview, and played great defense on five-star college prospect Jordan Lee, whom the Dons held to eight points.

Acalanes’ backcourt duo of Dulci Vail and KK Lacanlale scored the majority of the Dons’ points, with Vail leading the team with 22 and Lacanlale scoring 18. St. Mary’s is 11-4.

No. 20 Salesian 47, Pinole Valley 42 >> Madalyn Kanazawa scored 10 points, had five rebounds and dished out six assists as Salesian (4-7) outlasted Tri-County Athletic League rival Pinole Valley in a close win. Jamia Sawyer and Oriannah Birden scored eight points apiece for the Pride.
