Conference co-player of the year Pat Carroll added 16 points for
the Hawks (18-10), who have the tournament's top seed and have won
seven of their last eight games.
Saint Joseph's, which finished first in the East Division,
avoided a second consecutive quarterfinal upset in the tournament.
Last year, the Hawks were 27-0 before losing to Xavier 87-67 in the
A-10 tournament quarterfinals in Dayton.
Mallon averaged 3.1 points per game during the regular season.
His previous career-high was nine at La Salle on January 15. He
scored 12 points in the first half, including a 3-pointer with 5:02
left that gave Saint Joseph's its largest lead, 30-18.
The Spiders fought back to cut the lead to 30-28 before
halftime, but Carroll finished the half with five unanswered
points. He and Mallon each sank three free throws while Saint
Joseph's opened the second half with a 10-6 spurt for a 45-34 lead.
Carroll, one of the conference's most accurate 3-point shooters,
went only 3-of-14 from behind the arc. The senior guard had made
49.3 percent of his 3-point attempts in the last 17 games.
