"My effort on the court was a reason we have struggled, and I had to pick myself up and get a win," Galloway said.
How bad had the previous six games been?
"His last six games were the poorest [six-game stretch] he has played here," Martelli said.
Galloway averaged just 9.2 points in that span and shot 7 for 27 (25.9 percent) from three-point range. Last season, Galloway averaged 15.5 points and was fourth in the nation in three-point shooting (46.6 percent).
Carl Jones scored 15 and C.J. Aiken added 13.
Twelve of the 16 teams will qualify for the A-10 tournament. St. Joseph's (15-10, 6-6 A-10) is among the top 12, but still hasn't clinched a spot with four games left.
St. Joseph's had been outscored by 28 points in the first half of its previous three games, but looked fresh from the beginning after being off for a week.
The Hawks scored the game's first 12 points, and led by 20-2 barely five minutes into the game. They led, 40-29, at halftime.
Little has come easy this season, and despite the torrid start George Washington (12-13, 6-6) got to within 59-52 when Kevin Larsen hit two free throws with 5 minutes, 53 seconds left.
The Hawks then put the game away by scoring nine consecutive points on a three-pointer by Galloway and four free throws and an alley-oop dunk by Aiken.
Isaiah Armwood, who began his career at Villanova, led George Washington with 14 points.
Galloway, who hit 6 of 9 from beyond the arc, has had his strength sapped by illness this season, but he looked fresh Saturday.
Martelli said Galloway told him that illness had much to do with his play, but the coach wasn't buying it.
"I told him you haven't been the same aggressive player all year long, at either end of the floor," Martelli said.
That changed on Saturday and Galloway admits the statistics of the previous six games were a wake-up call.
"I hadn't averaged that low scoring through a period of six games I don't think my whole career," said Galloway, now averaging 13.8 points.
