BOSTON, Oct. 1 -- Devern Hansack pitched no-hit ball for five innings before Sunday's game was called because of rain, giving Boston a 9-0 win over Baltimore -- but not giving the Red Sox rookie official credit for a no-hitter.

In September 1991, a committee chaired by then-commissioner Fay Vincent changed rules that eliminated such performances from counting as no-hitters, wiping nearly 50 of them off the books. To stand, pitchers must allow no hits in a complete game that goes at least nine innings.

"I wasn't disappointed because nobody can stop the rain," said Hansack, a 28-year-old right-hander who worked as a lobsterman and pitched in his native Nicaragua the past two years, after his first major league win.

Hansack, in only his second major league start, put quite an ending on the 2006 regular season. All other games Sunday had ended by the time this one was called.

He was spotted at a tournament in the Netherlands by Craig Shipley, Boston's vice president for professional and international scouting.

"I was very excited, surprised, because I was out of baseball so long," said Hansack, who pitched in Houston's system in 2002 and 2003. "This is my opportunity. I can't mess it up."

Hansack (1-1) took the mound after a 3-hour 23-minute rain delay. He faced the minimum of 15 batters, allowing only Fernando Tatis to reach on a walk with one out in the second. Chris Gomez then grounded into a double play and Hansack retired the remaining nine batters, striking out four.

"That was fun, wasn't it, seeing him change speeds with the rain dripping off his cap," Boston Manager Terry Francona said. "The way he was able to throw strikes, he was really something special."

Hansack began warming up to start the sixth before the game was held up by rain. It was called 41 minutes later.

Hansack got plenty of support on a three-run homer by Mike Lowell and solo shots by Mark Loretta and Eric Hinske.

Hansack had spent this season helping Class AA Portland to the Eastern League championship, then made his first appearance in the majors for Boston on Sept. 23. He pitched five innings and took the loss against Toronto.

On Sunday, he struck out six and none of the other nine outs was close to a hit.

Boston failed to finish in second place for the first time in nine years, winding up one game behind Toronto and 11 behind New York in the American League East.

The Orioles finished the season with 50 losses in their last 76 road games and a 4-14 record against the Red Sox. It was Baltimore's ninth straight losing season, a team record.

"I think it's obvious we need some more pitching," Manager Sam Perlozzo said. "But there's a lot of good things that happened."
