Zanna, a 6-9 senior from Nigeria, was troublesome all night for Georgia Tech's thin front line. He made 8-of-10 field-goal tries for the Panthers (16-1, 4-0 ACC) and added a team-high nine rebounds. Robinson was 5-for-7 from the floor and posted his first double-figure scoring effort since Dec. 3.
Their effort helped offset one of the worst nights of the season for guard Lamar Patterson, a contender for ACC player of the year. Patterson failed to score in the first half and wound up with 12 on 4-of-13 shooting. Patterson did have a game-high seven assists.
Georgia Tech (10-7, 1-3 ACC) was led by guard Trae Golden with 22 points, including four 3-pointers. Forward Marcus Georges-Hunt scored 13 points before fouling out, and center Daniel Miller and forward Kammeon Holsey each scored 12.
The turning point came in the second half when Pitt went on a 9-0 run to erase a five-point deficit and take a 41-37 lead. The Panthers stretched the lead to 11 points at 53-42 on a jumper by Robinson with 11:10 left.
The game was close throughout the first half, with neither team able to lead by more than five points. There were seven ties in the first half. Pitt scored the first four points of the game and Georgia Tech didn't take the lead until Holsey's dunk with 10:42 put the Yellow Jackets ahead 14-13. Tech scored six of the last eight points of the half.
NOTES: Pitt was playing without forward Durand Johnson, a 6-foot-6 sophomore who had emerged as one of the top sixth men in the ACC. Johnson torn the ACL and meniscus on his right knee in Saturday's win against Wake Forest. ... Pitt moved in the rankings for the first time this week and landed at No. 22. ... Both teams play again Saturday. Pitt is back on the road against No. 2 Syracuse, while Georgia Tech completes a three-game homestand with a game against Miami.
