BOSTON (AP) Isaiah Jackson hit five free throws in the closing 33.9 seconds of overtime and finished with 19 points, lifting Providence to a 100-95 victory over Boston College on Tuesday night.
A.J. Reeves led the Friars (7-2) with 24 points and Alpha Diallo had 15. Watson added 10 rebounds. It was Providence's fourth straight victory.
Jordan Chatman led Boston College (6-2) with 28 points, Ky Bowman and Wynston Tabbs each had 17, and Jairus Hamilton had 13 before fouling out. The Eagles had their four-game winning streak snapped.
It was the 113th meeting between the schools, with the first coming in 1946.
In a final two minutes of overtime filled with whistles and trips to the foul line, Watson hit two free throws, giving Providence a 95-93 edge with 1:12 to play.
Chatman made just one of two before Jackson hit a pair, making it 97-94 with 33.9 seconds left.
After Bowman hit a free throw, slicing it to 97-95, BC was forced to foul Jackson twice. He hit three of four to seal it.
Boston College had opened an 84-81 lead on Hamilton's dunk, but Maliek White had a conventional 3-point play with 48 seconds left in regulation.
Bowman then hit one of two from the line, giving BC an 85-84 edge with 35.1 seconds left.
Chatman was fouled grabbing a rebound on Maliek White's missed 3-pointer and hit both from the line before A.J. Reeves nailed a 3 from the top of the key, tying it at 87 with 2.6 seconds left.
BC rushed the ball up and Bowman missed a 3 from the left wing, sending it to OT.
The Eagles led 43-39 at halftime.
In the first half, Providence had opened a 33-22 lead on Jackson's 3 with just under seven minutes left, but Chris Herren Jr. had three from beyond the arc in BC's 15-0 spurt over a 2:24 stretch.
Providence: Coach Ed Cooley, a former BC assistant for many years, won his first game as an opposing coach at Conte Forum. He was 0-3 with PC. . Watson, a 6-foot-10 sophomore, gave BC trouble inside and should help in the Big East.
Boston College: The Eagles' freshmen seemed to be gaining confidence each game. Tabbs has already been a pleasant surprise for them by scoring, but forward and highly-touted recruit Hamilton and guard Herren both are playing meaningful minutes and offering more scoring and support for Bowman.
SHORT UP FRONT
BC forward Nik Popovic was sidelined and in the concussion protocol after a hit he took in practice Sunday.
The 6-foot-11 junior had been playing some of his best minutes of his career with the Eagles when he scored in double figures the last three games, including going 9 for 9 from the floor when he had 18 points in a win over Minnesota on November 26.
YOUNG AT HEART
Providence started three freshmen - as it has for most of the season.
Guards Reeves and David Duke started their sixth straight along with forward Jimmy Nichols.
BC debuted alternative home white uniforms with script ''Eagles'' on the front of the jerseys for the first time since the 1961-62 season.
Providence: Hosts Massachusetts on Friday night.
Boston College: Plays at Texas A&M on Saturday night.
