Brown scored a game-high 28 points and grabbed 11 rebounds to lead a trio of Rock players who finished the game with double-digit scoring totals.

SRU outscored the hosts by an 17-4 margin in the next seven minutes, though, to take a six-point (30-24) lead with 4:15 left before the intermission.

The Griffins tied the score at 46-46 with 12:30 left in the game and took a 47-46 lead 30 seconds later, only to have Bailey can a pair of free throws to put The Rock back on top by one point (48-47) with 11:45 left.
A 10-0 Rock run stretched the Green and White's lead to 11 points (58-47), the first double-digit lead held by either team, with eight minutes remaining and the Griffins never got closer than eight points thereafter.
The Rock held its largest lead of the game, 76-57, with just less than a minute left to play.
Notes: Brown now ranks 15th on SRU’s career rebounding chart with 582 in three seasons ... Saturday's game marked the fourth time in as many games this winter Bailey scored 19 or more points ... Saturday's win was the 38th recorded by Rock Head Coach Kevin Reynolds in three seasons at SRU and moved him into a tie with Bob Smiley (1952-55) for the third highest win total recorded by a Rock coach in his first three seasons. The next Rock win will move Reynolds, who set school records for most wins by a first-year (21) and second-year (36) Rock head coach, into a tie with Hank Baierl (1958-61) for the most wins in three seasons. Mel Hankinson (1970-73) holds the school record for three-year wins with 50.
