There aren’t a lot more chances left for Brewers pitcher Jim Abbott. In fact, today may be his last start of a heroic career when the Yankees’ former no-hit hero faces the Mets in the first game of a Shea Stadium twinbill.

And Abbott knows it, feels it, which is why the one-handed sensation was the most disappointed player last night when his scheduled start was postponed by Shea showers.

Abbott, 31, was out of baseball in 1997. So far, he has failed miserably in a comeback with the Brewers, banished to the bullpen after being brutalized in his first four starts.

Today, Abbott, 0-4 with a 8.49 ERA, will make his first start in three weeks.

“We all feel our mortality career-wise but it’s something you stay away from,” Abbott said. “I don’t look at these as hard times. I’m not happy the way I’m pitching but things could be a lot worse.”

Indeed, the good-natured Abbott still has it all in perspective, just like when he was in The Bronx.

“I’ve been out of the major leagues now, so I appreciate putting on that uniform,” said Abbott. “I appreciate coming to Shea Stadium. I appreciate the opportunity to pitch tomorrow. Every time I get that chance, I’m going to savor it because I know how quickly it could go away, whether I play for five more years or I play for the rest of this year.”

He has a one-year deal with the Brewers for $400,000. After sitting out in ’97, Abbott played in the White Sox minor league system last season before a September big-league promotion. He opened eyes with a 5-0 September, even beating the Yankees in his very first start in two years.

But the comeback story has gone sour. If he continues this path, the Brewers won’t be renewing his $1.5 million option for next season and instead will buy him out at $200,000.

“We brought him on because of his experience and demeanor,” Brewers manager Phil Garner. “He’s a terrific guy to have on the ballclub. He doesn’t throw the ball the way he used to so he’s got to throw differently with different speeds on his changeup. That takes time to learn.”
