The Harvard baseball team swept Army and split with Columbia in Eastern Intercollegiate Baseball League doubleheaders this weekend, raising its league record to 7-5 (13-8 overall).

But Navy's sweep of Penn gave the 15-3 Midshipmen--who have now completed their league schedule--outright ownership of the title, erasing the Crimson's hope of a comeback bid.

Last year, the batswomen closed the season with a 10-game EIBL winning streak to force a post-season playoff with Princeton.

Although Navy's supremacy nixed any similar comeback plans this season, Crimson Coach Alex Nahigian did salvage one bonus from this weekend: he won his 400th collegiate contest Saturday.

Harvard 2, Army 1

In the opener at West Point, N.Y., Crimson starter Chris Marchok continued to master EIBL hitters, allowing only four hits and three walks while hurling his third consecutive complete game. His victims--Brown, Navy, and Army--have scored just five runs and suffered 20 strikeouts under the Wrath of Marchok.

The junior pitcher raised his record to 2-1 and lowered his ERA to a phenomenal 1.66.

Marchok, however, spotted the opposition to an early 1-0 lead. In the first inning, Cadet Mike Iacobucci walked, advanced to third on a double, and scored on a single by Dan Kirk.

But Harvard retaliated with two runs in the third inning.

Dave Jamieson put the Crimson on the board with a home run to right field off Army starting pitcher Rich Krafft (now 4-2). Crimson centerfielder Paul Vallone scored the winning run on a sacrifice fly from designated hitter Jim DePalo--the clean-up hitter's 14th RBI of the season.

Those two runs were all Harvard needed, as Marchok gave up only two additional hits and struck out six Cadets on the day.

Nahigian had to be happy about the nightcap--if not for his 400th victory, then for Mike Presz's strong pitching.

Presz, who extended his record to 3-0 in 1986 (11-0 in his three years at Harvard), struck out seven Cadets and allowed but one walk in his first complete game of the season.

The Crimson provided the junior hurler with a 4-0 lead when it struck for runs in the second and third innings.
