Crimson puckster Neil Sheehy has a streak going. For the past four years, the blueliner has managed to score a goal on his birthday. The feat is doubly impressive because the odds of his team having a game scheduled that date every year are not good. But so far, the dates have worked out, and so far Sheehy has managed to pop one home.

That's good for the icemen because on Sheehy's birthday this year--Monday night--they will be attempting to win Harvard's first Beanpot championship since 1977. Sheehy and his teammates will take the ice at 8 p.m. before an expected capacity crowd at the Boston Garden, and try to knock off a Boston College sextet, the team with the fewest losses in the country (two). The festivities start at 5 p.m. with the B.U. Northeastern consolation game, and, if Harvard wins, will continue well into the night, highlighted by the traditional concert on the Red Line by the Harvard band.

The men's basketball team has a streak of its own--six straight wins, the longest since a seven-gamer in 1970-71. That skein is on the line this afternoon, when the hoopsters meet Merrimack at the IAB in a 2 p.m. start. Should the Crimson win, the resulting seven-game streak will tie the longest streak in Harvard history.

Following today's outing, the hoopsters take to the road, traveling to Dartmouth on Wednesday and Penn on Friday. Both games can be heard over WHRB with Jay Weinstein and Ed Murphy.

The women's basketball team will be doing some traveling, too, busing to Southern Connecticut this afternoon, and to Boston University Wednesday night. The women's hockey team will host Yale at the Bright Center this afternoon, and then head north to Dartmouth on Wednesday.

Sunday afternoon, coach Bill McCurdy's men's track team will attempt to win the Greater Boston Track Championships at the ITT. The preliminaries are tonight.

The men's swim team will also be competing against Greater Boston opponents this week. The 1981 GBCs will be held Tuesday afternoon at MIT. Before that, however, the aquamen travel to Princeton for a key Ivy match with the Tigers this evening.

Also at Princeton for an important match is the men's squash team. That contest, scheduled for 2 p.m., may decide the national championship. The women's swim team is there, too, in a 1 p.m. start.
