Senior forward Kevin Boddie had six blocked shots and Catholic University used a pesky man-to-man defense to defeat Massachusetts Institute of Technology, 78-60, in an opening round game of the inaugural Eastern Invitational last night at the Raymond DuFour Arena.

The Cardinals (17-7) will meet Connecticut College (14-7), a 72-65 victor over St. Mary's College (Md.), in the semifinal round Saturday at 9 p.m. In the other semifinal, Union College (11-12), which defeated New York University, 108-99, will play Emory University (13-11), a 100-86 winner over Mary Washington, at 7.

Catholic, which has been defeated three times at home in the last three seasons, put together several spurts throughout the game. The final blow, a 17-5 run late in the second half, gave Catholic a 71-53 lead with 3:05 to play.

In the first half, both teams had trouble scoring, as Catholic shot 40.6 percent on 13 of 32 from the field and MIT 29 percent on nine of 31. But Kevin Morrison, who had 20 points and 11 rebounds, scored on a tip to give Catholic a 31-28 halftime advantage.

In the opening minutes of the second half, Boddie (eight points, five rebounds) and Catholic protected the middle, forcing the Engineers into numerous turnovers and errant shots from the outside to move in front, 39-33, with 15:55 left.

Doug Cornwall had 19 points and nine rebounds to lead MIT.
