Sean McGonigal scored seven of his 23 points in overtime to lead Brown to a come-from-behind victory over Niagara, 75-74, Tuesday night in the Pizzitola Center in Providence, R.I.

It was a matter of the Purple Eagles (7-8) being unable to hold a lead against the Bruins (5-8). Niagara led 37-27 at the half but went scoreless the first 4½ minutes of the second half as Brown closed the gap. Niagara was 0 for 5 from three-point range during that dry spell. NU led 62-56 with 1:32 to play in regulation after a Tahjere McCall layup, but Matt Sullivan of the Bruins scored six points in a row to tie it, evening the score at 62-all on a three-point shot with 13 seconds to go.

Niagara led by three points early in the OT, but McGonigal tied it with a three before a jump shot by Cedric Kuakumensah gave Brown the lead for good.

Sullivan had 20 points for Brown.

Four Niagara starters were in double figures — Ameen Tanksley (18), Juan’ya Green 17, Antoine Mason 13 and Devon White 11.
