The Red Storm (5-3, 0-2 Big East) led by seven with less than three minutes to go in regulation, and led by four just over a minute into the overtime frame. The Hoyas (3-3, 1-1) answered with 8-1 runs on both occasions.
Isaih Moore led the way for St. John’s by shattering a pair of career-highs. The former junior college All-American recorded 26 points on 10-of-18 shooting to go along with 14 rebounds.
He also blocked a pair of shots in 32 minutes of action. Prior to Sunday, Moore had never scored more than 13 points or grabbed more than nine rebounds in a Division I game.
He became the first St. John’s player to record 14 boards in a game since Tariq Owens did so in 2017.
Moore was one of two Johnnies to finish with a double-double on Sunday, as Julian Champagnie tallied 13 points and 12 boards for his third double-double in just six appearances this season.
In total, five St. John’s players reached double figures for the first time this season and just the second time in the last two years.
Posh Alexander registered 16 points on 6-of-12 shooting to go along with six assists and two steals, while Williams scored 13 and Marcellus Earlington added 10 in just 13 minutes of action.
Alexander recorded four of his assists in the final four minutes of the second half, including one on the Williams buzzer-beater to send the game into overtime.
As a team, St. John’s won the battle of the boards, 45-34, including a 20-6 margin on the offensive glass. The Hoyas proved much more efficient at converting those chances, however, as St. John’s recorded 19 second-chance points while Georgetown managed 14.
On the evening, the Hoyas shot 53.9 percent from the floor (34-of-63) and converted on 11 of their 23 attempts from beyond the arc (47.8 percent). St. John’s turned in a 43.4 field goal percentage and sank only four of its 13 long-range tries.
Sophomore center Qudus Wahab narrowly missed a triple-double for the Hoyas, finishing with 17 points, 10 rebounds and nine blocks. Jalen Harris, a graduate transfer who played for Mike Anderson at Arkansas, scored a team-high 22 points while Jahvon Blair added 20 points and five assists.
The Red Storm will return to action on Thursday when its hosts eighth-ranked Creighton at Carnesecca Arena. Tip-off is scheduled for 5 p.m. on FS1. The Hoyas will then make the return trip to Queens on Sunday at 6:30 p.m.
