ST. LOUIS -- Wednesday's game was billed as a matchup of the Atlantic 10 Conference's best defensive teams.

Only one team showed up ready to lock down its opponent.

Holding Richmond guards Cedrick Lindsay and Kendall Anthony to a combined 10-of-31 shooting from the field and well under their combined average of 32.5 points per game, No. 19 Saint Louis led wire to wire in a 77-57 blowout Wednesday night at Chaifetz Arena.

It was the 13th consecutive win for the Billikens (19-2, 6-0), who haven't lost since dropping a 70-65 decision to No. 4 Wichita State on Dec. 1. They remain atop the A-10, with the Spiders (14-7, 4-2) falling two games back.

Senior guard Jordair Jett turned in a 21-point, 10-rebound double-double for Saint Louis. Forward Dwayne Evans added 15 points and 10 boards. Guard Austin McBroom came off the bench to score 12, and center Rob Loe contributed 10 points.

Anthony finished with 14 points to lead Richmond. Lindsay added 12, and forward Derrick Williams tallied 10 points to go along with 10 rebounds. Lindsay came into the game averaging 18.5 points per game, second in the conference, and Anthony was scoring 14 per game.

The Billikens and Spiders entered the night allowing 58 and 64.7 points per game, respectively, to lead the conference. However, Saint Louis canned 51.9 percent of its field goals and held Richmond to an ugly 20-of-63 (31.7 percent) from the floor.

Saint Louis had the A-10's weekend bye and used it wisely, installing some different offensive sets to counter Richmond's tricky matchup zone.

The Billikens executed crisply from the start, opening up a 17-5 lead on a 3-pointer by Loe with 12:04 left in the first half and forcing Spiders coach Chris Mooney to ask for timeout.

But Richmond, which entered the game with four straight wins, simply couldn't do much to keep Saint Louis from rolling downhill for the half's remainder. Getting favorable individual matchups, the Billikens made 53.3 percent of their field goals.

Jett's runner with 1:24 remaining upped their advantage to 24 points. After a 3-pointer from Anthony, Saint Louis settled for a 42-21 halftime lead.
