Brett Roseboro posted his first career double-double with 19 pts/10 rebs.
BALTIMORE- UMBC senior guard Ryan Cook (Laurel, Md./Pallotti) scored 18 of his game-high 22 points in the second half and junior post Brett Roseboro (Quakertown, Pa./Quakertown) posted career highs with 19 points and 10 rebounds as the host Retrievers (2-5) never trailed in a 66-62 victory over Towson (3-4) .
Cook became the tenth player in school history to convert at least 10 free throws in a game without a missed attempt, as he converted all 10 of his shots in the second half.
It was the 20th win in the series for UMBC against 34 setbacks. The Retrievers have won two straight in the series, as Towson is UMBC's most-contested foe.
UMBC jumped out to a 9-0 advantage in the first 3:38 of play, but the Tigers chipped away and only trailed, 23-22, at the half.
Towson would tie the game twice, at 34-all with 13:16 remaining, and at 36-36 at the 12:44 mark. But Cook triggered a 6-0 run with a pair of free throws after a drive to the bucket and capped the run with a short right-side baseline jumper.
UMBC would extend the run to 13-3 on a Chase Plummer (Plainfield, N.J./St. Patrick) 3-point field goal with two seconds left on the shot clock and the Retrievers led, 49-39 with 6:35 to play.
Towson cut the advantage to 54-51 on a Kris Walden trey with 3:34 to play, but an unguarded Plummer replied from behind the arc on the next possession to restore the lead to six points.
Cook put UMBC ahead, 62-54 with 38 seconds left, but the Tigers clawed back to make it a one possession game. Junior forward Jerelle Benimon converted a quick layup, and Cook committed a turnover and subsequent foul on the ensuing inbounds play. Walden missed both free throw attempts, but Benimon got the offensive board and converted a 3-point play to bring Towson within 62-59 with 28 seconds to play.
But Cook redeemed himself by knocking down two free throw attempts three seconds later and, after a Tiger missed shot, hit two more to seal the victory with seven seconds to play.
Walden swished a trey with less than one second remaining to make the final score 66-62.
Roseboro hit 9-of-11 shots from the floor before fouling out with 28 seconds remaining. The 6-foot-10 St. Bonaventure transfer had just posted a career-best 13 points vs. Canisius two nights ago.
Plummer also posted a double-double, the eighth of his career, with 11 points and 11 rebounds.
Benimon had 13 points and a game-high 16 rebounds for Towson. Guards Mike Burwell and Jerome Hairston led the Tigers with 14 points each.
UMBC hit 14-of-29 shots in the second half and finished at 41.8 percent (23-of-55) for the game. Towson was below the 40 percent mark in both halves and completed play at 37 percent (20-of-54). Towson garnered 16 offensive caroms and outrebounded the smaller Retrievers, 43-34.
The Retrievers turned the ball over a season-low 11 times.
UMBC faces another CAA opponent on Tuesday, when they travel to George Mason to take on the Patriots.
