"No matter what happens, we still believe we're going to win the game," Roman senior Shep Garner said. "We just have that mind-set."
Roman, ranked No. 1 in Southeastern Pennsylvania by The Inquirer, will play for top Catholic League honors at 8:30 p.m. Monday at the Palestra.
Against La Salle, which trailed by 39-24 entering the fourth quarter, a quick start and balanced scoring were key for the Cahillites.
Sophomore floor general Tony Carr (12 points), junior forward Manny Taylor (10), and junior wing Gemil Holbrook (10) were double-digit scorers. Garner and fellow senior guard Rashann London scored nine and eight points, respectively.
"That's been the way it's been all year for us, which is good," McNesby said. "We have multiple players who can score."
The Explorers' comeback was sparked by 6-foot-7 forward Dave Krmpotich (15 points, 10 boards, three blocks) and Greenberg (11 points).
Greenberg's third three-pointer of the game trimmed Roman's lead to 44-40 with 3 minutes, 38 seconds to go. Najee Walls' trey from up top brought La Salle to within three (46-43) with 1:18 left.
"Credit La Salle," McNesby said. "They weren't going to go away quietly. They fought hard, battled. They weren't going to lie down."
London, Garner, and Holbrook each went 2 for 2 from the line in the last 35 seconds. The Cahillites were 9 for 11 on free throws in the fourth period and 18 for 23 overall.
Roman played without 6-6 junior TreVaughn Wilkerson, who had suffered an ankle injury in practice Sunday.
