The Hoyas finished in first place in the Big East's regular season, the second time in three seasons and fourth time in school history that they had finished in first or tied for first. They won the
1989 Big East tournament, defeating fifth-ranked Syracuse in the final for the sixth Big East tournament championship in Georgetown history. Charles Smith averaged 22 points per game over the Hoyas' three tournament games. The Hoyas were the No. 1 seed in the East Region of the
1989 NCAA Division I men's basketball tournament – the 11th of 14 consecutive Georgetown
NCAA tournament appearances. In
their first round game against
Ivy League champion
Princeton, Smith shot only 2-for-12 from the field and the Hoyas barely escaped an upset. Princeton employed a 1950s-era offense and scored 14 of their 21
field goals off of layups off back-door screens, and, after Mourning blocked a last-second Princeton shot that some observers believed should have been called a
personal foul against him, Georgetown barely eked out a 50–49 victory. In the second round, Smith scored 34 points to lead Georgetown to a win over
Notre Dame, but he twisted his ankle, and the injury made him ineffective in the East Region semifinal against
North Carolina State, in which he scored only a single point. Bryant scored a team-high 24 points and Jackson scored 17, however, and the Hoyas again emerged with a victory. In the East Region final, Georgetown faced the region's No. 2 seed,
Duke. Smith scored 21 points and Tillmon 16, but Jackson managed only 1-for-10 shooting from the field. The Blue Devils, led by
Danny Ferry and freshman
Christian Laettner built an early lead that they never relinquished, and they knocked the Hoyas out of the tournament, bringing Georgetown's season to an end, with the 85–77 loss. The Hoyas were ranked No. 2 in the season's final
Associated Press Poll and
Coaches' Poll behind only Arizona. Although it was not apparent at the time, Duke's defeat of Georgetown signaled a change in the balance of power in men's college basketball. While Duke was on the rise entering the 1990s, the Hoyas' era of dominance was beginning to come to a close. Georgetown would not win the Big East tournament again until the
2007–08 team won
in 2008, and before the 2007–08 team's
Final Four appearance in the
2008 NCAA tournament, the Hoyas would make an
Elite Eight appearance only once, when the
1995–96 team advanced to the East Region final of the
1996 NCAA tournament. ==Roster==
