Repeating their heroics of last weekend, Crimson pitchers Chris Marchok, Kevin Curtin and Bob Baxter all tossed complete games in leading the Harvard baseball team to three wins in four games against Princeton Saturday and Cornell yesterday.

But in yesterday's extra-inning nightcap, Cornell spoiled Harvard's bid for a weekend sweep, rallying for two runs in the bottom of the eighth after Harvard had broken a 5-5 tie in the top of the inning.

The Crimson's split with Cornell, coupled with Dartmouth's sweep of Princeton, locked the two teams into a first-place tie in the Eastern Intercollegiate Baseball League (EIBL) with 12-2 marks. Navy is next at 11-3.

The EIBL title will likely be decided next Saturday when the Crimson (15-4 overall) travels to Hanover, N.H., to play a doubleheader with the Big Green.

Harvard 11, Cornell 0

In yesterday's opener in Ithaca, N.Y., Curtin struck out seven Cornell batters and gave up only three hits, improving his record to 3-0 while dropping his ERA to 0.73.

The senior from Burlington recorded his third complete game in as many EIBL starts. In his 24-2/3 innings of pitching this season, Curtin has allowed just 15 hits and 9 walks.

The Crimson tallied three times in the second, once in the third, four times in the fourth, and three more in the fifth to provide Curtin with plenty of support.

In the second inning, five singles and two fielder's choices off loser Rob Deans (1-6) gave Harvard an early 3-0 lead.

Captain Mike Pakalnis and Jim DePalo (both 3-for-5), Craig Boulris (2-for-4), and Frank Caprio (2-for-5) led the Crimson's 17-hit barrage.

Cornell 7, Harvard 6 (8 inn.)

Although first baseman Rich Renninger doubled in Dan McConaghy in the top of the eighth to give Harvard a 6-5 lead, the Big Red scored twice in the bottom of the frame to gain a split in yesterday's doubleheader.

Cornell's Scott Kenney singled off loser Vic McGrady (now 2-1) with one out in the eighth, driving in Dave Dase from third base to tie the game. Mark Smith followed with another single to score Joe Toscano for the winning run.

Big Red starting pitcher John O'Connor (4-1 EIBL) took a two-hitter and a 5-0 lead into the sixth inning, but the Crimson--behind five singles, a double, and a ground out--was able to tie the contest at five runs apiece.
