PHILADELPHIA (AP) -- Chatilla van Grinsven scored 18 points and Saint Joseph's stunned No. 5 Maryland 50-49 on Saturday.
The Hawks (2-1) defeated a ranked team for the first time since a victory over No. 15 Auburn on Dec. 29, 2007.
Saint Joseph's had dropped 10 straight games to the Terrapins before this one but held Maryland scoreless over the final seven minutes.
Alyssa Thomas had 16 points and 15 rebounds while Laurin Mincy added 14 points for the Terrapins (2-1), who opened the season with a 39-point victory over Mount St. Mary's and a 43-point win over Loyola.
Maryland, a regional finalist in last season's NCAA tournament, couldn't shake the Hawks, even after building a 47-38 lead with 9:10 remaining.
Saint Joseph's responded with a 12-2 run to take a 50-49 lead with 4:21 left. The Terrapins committed five of their 19 turnovers during the spurt.
Thomas hit a jumper for a 49-44 lead with seven minutes remaining, but that was all the offense the Terrapins would muster the rest of the game.
Still, Maryland had three chances to win in the final 19 seconds.
Katie Rutan missed a jumper and Thomas had her follow shot blocked by van Grinsven.
The Terrapins had one last chance with less than a second left, but Tianna Hawkins misfired from the baseline and the Saint Joseph's bench erupted in celebration.
Erin Shields added 10 points for the Hawks, who won despite being outrebounded 47-27. Thomas had nine offensive rebounds.
Neither team hit a 3-pointer in the second half. Hawkins managed just two points after scoring 51 in the first two games.
