St. Joseph's made its biggest basketball statement of the season, but it wasn't without plenty of anxiety. After taking a 16-point halftime lead, the Hawks held off a late Massachusetts surge to defeat the Minutemen, 73-68, on Saturday in an Atlantic Ten game at Hagan Arena. St. Joseph's is 15-6 overall and tied for third in the A-10 with a 5-2 mark. UMass, ranked No. 19 in the coaches poll and No. 21 by the Associated Press, is 17-4, 4-3. It was the Hawks' first win over a ranked team since beating No. 20 Notre Dame, 79-70, in overtime on Nov. 16, 2012. This week, the Hawks will host the A-10's top two teams: St. Louis on Wednesday and Virginia Commonwealth on Saturday. A successful week would clearly put the Hawks in the NCAA tournament conversation. St. Joe's received 48 points from its starting frontcourt: 18 from Halil Kanacevic, 17 from Ronald Roberts Jr., and 13 from DeAndre' Bembry. Point guard Chris Wilson scored 12 points. He has scored in double figures in five of the last six games. Leading scorer Langston Galloway, who was saddled with foul trouble, scored a season-low seven points. UMass was led by Derrick Gordon, who scored 21 points. Point guard Chaz Williams, who had 22 points in UMass' 66-62 win over the Hawks on Jan. 8, scored 13 of his 16 points in the second half. On Saturday, St. Joseph's led by as many as 17 points and owned a 41-25 halftime lead. "Sometimes you have to find a way," Wilson said. "It is going to be ugly, and we're mad about giving up the lead, but either way it goes in the same column." In the second half, UMass showed greater intensity on defense. "It was gutty, and we did what we had to do to win a game, but I am concerned about our offense," said St. Joseph's coach Phil Martelli, whose team shot 21 of 51 from the field and 25 of 40 from the foul line.
