Marietta, OH - Montclair State moved to within a victory of its first national baseball championship yesterday by shocking the No. 1 team in the country, Wisconsin-Oshkosh, 13-4 in the third day of action at the Division 3 World Series held in Pioneer Park.

The Indians (33-14-1), making their fifth straight appearance in the World Series, became the lone undefeated team (3-0) in the double-elimination format by snapping Wisconsin-Oshkosh's 21-game winning streak. Montclair will go after the championship today at 12:30 pm again against Wisconsin-Oshkosh, which ousted North Carolina Wesleyan 10-9 yesterday. If Montclair loses, a second game will be played 20 minutes later to decide the World Series title.

Wesleyan had eliminated Eastern Connecticut in yesterday's first game when Garry Ormsby stole home with two outs in the bottom of the ninth to snap a 3-3 tie. Ormsby stole his 76th base with the count 0-2 and a left-handed batter at the plate.

"This team has a lot of guts," said shortstop JIM FASANO, who is playing in his third World Series for Montclair State. "The other two teams I played on here had more talent, but this team has more guts. No matter what the score, everybody believes that we're going to win."

The Indians turnd the tables on Wisconsin-Oshkosh (36-4) handing the Titans the kind of defeat they had been used to administering to the other World Series participants. Wisconsin-Oshkosh, the 1985 winner, had 27 runs and 28 hits in winning its first two games of the series by scores of 16-1 and 11-6.

Both coaches decided to hold back their No. 1 starter from this game and JEFF VANDEROEF of Montclair was clearly the superior pitcher on this day. The sophomore righander from Basking Ridge gave up six hits and two earned runs in improving his record to 10-1. He struck out six and walked four.

Wisconsin starter and loser Scott Hestnes (6-1) left in the fifth when the Indians opened up the inning with three straight hits. The Indians had take the lead for good in the fourth when catcher Bill Coyle lined an opposite-field double off the wall in right center to score two runs and put Montclair on top, 4-2.

"Everyone was worried about Wisconsin-Oshkosh, but we showed them something," said Coyle. "We're reach for any team. No one can stop us this year."

KEVIN CAVALLO opened the fifth fo the Indians with a single and Fasano, who had three hits, scored three and drove in one, lined a hit-and-run single to right. JOHN MCCLAIN delivered Cavallo with a single for a 5-2 score before Troy Lillicrop relieved for the Titans.

Fasano scored to make it 6-2 in the fifth when JOHN DEUTSCH grounded into a double play. Todd Schliem led off the sixth with a homer to cut Oshkosh's deficit to 6-3 before the Indians went on the warpath in the bottom of the inning. Montclair scored six times in the sixth on just two hits to take a 12-3 lead. LEROY HORN started off the big inning by reaching on an error, one of four committed by the Titans, who hadn't lost a game since April 14 when the University of Minnesota beat them twice.

MIKE WENRICH walked on four pitched before Coyle flew to right. A wild pitch moved the runners to second and third and PETE DIAZ walked to load them up. Cavallo drew an RBI walk and Fasano followed with a sacrifice fly. It was 9-3 before Deutsch ripped a two-run single to center for Montclair's first hit of the inning. Deutsch advanced on a wild pitch before PEPE HERRERO doubled to the gap in left center for the 12th run. It was Herrero's 64th RBI of the year.

Deutsch, the 6-6, 235 pound sophomore, singled home Fasano, who had doubled, in the eighth to give him three hits and three RBI in the game. The right fielder has 74 RBI, four more than the Montclair season record set by Bob Yeager in 1985.

While the Indians were piling up 12 hits and geting at least one run from eight spots in the batting order, Vanderoef was in control over a Tital offense that came into the game with a .424 team batting average. After yielding three hits and two unearned runs in the third, Schliem's homer was the only telling stroke made by Wisconsin-Oshkosh the rest of the game.

"It was the best I felt all year," said Vanderoef, who gave up one hit over the final three innings and struck out the last two batters of the game "I just had to get used to the strike zone which was tight. I mixed in a lot of different pitches early, but from the sixth inning on, I threw mostly fastballs."

Montclair coach Kevin Cooney will probably bring back BRIAN DEVINS (9-2) to pitch today. The freshman lefthander, who won all three games in the Mid-Atlantic Region, worked 5 2/3 innings Thursday without getting a decision in a 10-8 victory over Eastern Connecticut.

"Last year we were 2-0 and lost to Ithaca and were eliminated by Marietta," said Cooney. "What I'm going to tell my kids is that Ithaca was 3-0 at this point last year and lost. We haven't won anything yet. But we've been the bridesmaids long enough. Now it's time to get that ring on our finger."

"Man for man, position for position, we've had better teams complete in the World Series," added Cooney. "But no team has the heart that his team has."
