Martynas Andriuskevicius scored all of his 11 points in the final 3:36 Monday night, and the Chicago Bulls remained undefeated in pre-season play with an 87-78 victory over the Memphis Grizzlies.

Andriuskevicius, the seven-foot-two second-year player from Lithuania, played only nine minutes, all in the fourth period, but took control down the stretch as Memphis tried to pull even.

Tyrus Thomas, the rookie from LSU, led the Bulls (3-0) with 12 points, while Luol Deng and Malik Allen each added 10. Viktor Khryapa, who has led the Bulls in assists in each pre-season games, had eight.

Hakim Warrick led Memphis (2-2) with 13 points, while Damon Stoudamire added 12. Dahntay Jones, Lawrence Roberts and Alexander Johnson finished with 11 apiece. Johnson grabbed 10 rebounds.

The Grizzlies missed six of their first seven free throws in the final quarter, and went only 3-of-10 in the period. Memphis hit 53 per cent for the game (19-of-36).

While the Grizzlies' problems were at the line, the Bulls had trouble handling the ball. Chicago committed 27 turnovers in the game, leading to 25 Memphis points.

Memphis rookie forward Rudy Gay did not play because of a bruised chest. That, with several other key injuries, left the Grizzlies with a starting frontline of six-foot-six Jones with Roberts and Warrick, both six-foot-nine, and only nine players available. Then, reserve Junior Harrington went out with about nine minutes left in the game when he caught an elbow in the head from Thomas that took five stitches to close.

Foul trouble on P.J. Brown got Thomas some early playing time, and the rookie had 10 of his points in the first half as the Bulls built a 46-40 lead at intermission.

Chicago led by as many as nine in the first half while shooting 52 per cent from the field. The teams were a combined 0-of-13 outside the arc in the game until Chucky Atkins hit with 4:08 left, the only three-pointer of the game.

The Bulls carried a 64-58 lead into the final period as the Chicago starters sat out the fourth.
