Big league baseball teams generally don’t make trades during spring training. To borrow from the old Bill Parcells line, the grocery shopping is done in November, December and January, and then the meal gets cooked once spring training starts.

Exceptions? Sure. Spring training was barely under way in 1999 when the Yankees shocked the world by acquiring Roger Clemens from the Toronto Blue Jays.

And in a move that haunts the Red Sox to this day, then-general manager Theo Epstein made a big spring training move in 2006 when he sent reliable right-hander Bronson Arroyo to the Cincinnati Reds for Wily Mo Pena, a slugging outfielder who didn’t do much slugging once he joined the Red Sox . . . and couldn’t play the outfield.

“I was here when that happened,” lamented current Red Sox GM Ben Cherington, an Epstein assistant in 2006. “We’ll try not to repeat that one.”

Cherington sailed through spring training last year, his first as GM of the Red Sox, without making any deals. But even he admits that this year could be different.

“I could see the possibility of a move,” said Cherington, who then paused for a beat and added, “I could see the possibility of no moves.”

So there.

But once he had the disclaimer out of the way, Cherington cut to the chase.

“We have a scenario where the 25 men on our roster come from the guys who are here, and there are no trades at all,” he said. “But, yeah, we’ll keep an eye open if there are opportunities. There’s a little bit of depth in certain areas that teams may be interested in.”

A little bit of depth . . . and a little bit of trouble.
