ST. LOUIS (AP) -- Derrick Brown made a tip-in with 0.1 seconds to go, enabling No. 13 Xavier to barely avoid a second-half meltdown in a 70-68 victory over Saint Louis on Thursday night.

Josh Duncan led a balanced atack with 15 points for Xavier (19-4, 7-1 Atlantic 10), which squandered all of a 16-point cushion against the persistent Billikens. Drew Lavender added 13 points and three others scored in double figures for Xavier, which has won five in a row and 11 of 12.

Kevin Lisch had three 3-pointers and a three-point play in the final minute, and his driving layup and free throw with 11.6 seconds to go tied it at 68. Lisch was a career-best 6-for-9 from 3-point range and scored 25 points for Saint Louis, which also got 11 points from Luke Meyer and 10 from III.

Brown, who finished with 12 points and nine rebounds, tipped in a missed shot by a driving Drew Lavender just ahead of the buzzer.

Saint Louis led only once after Barry Eberhardt's 3 for a 13-12 lead with 12:18 to go in the first half. Eberhardt was 2-for-2 from 3-point range and is 7-for-13 on the year after hitting another from long range during Saint Louis' comeback.

Xavier held Saint to 27-percent shooting while taking a 35-22 lead at the break. It's the Billikens' worst showing for a half outside of a horrid 14.6-percent showing, the NCAA's worst in the shot clock era, in a 49-20 loss at George Washington Jan. 10.

Duncan and C.J. Anderson each had two baskets in a 10-0 run that put the Musketeers in control at 29-15 with just over four minutes to go. Duncan hit his first four shots and had 13 points in the half, while Lavender hit his first three shots and had eight points.

Anderson, who played his first two seasons at Manhattan, topped 1,000 career points on his first basket. He's the third player on the team to do it, joining Burrell and Lavender.
