All-star first baseman Don Mattingly is close to re-signing with the New York Yankees, according to the New York Daily News. The newspaper reported that Mattingly is expected to approve shortly a three-year deal worth $6.7 million . . .

Pitcher Dennis Martinez said he intends to re-sign with the Montreal Expos even though returning to Baltimore would be a "dream come true." Martinez, 11-4 with a 3.30 ERA in 1987, said he would only discuss a contract for next season with the Orioles if he can't work out a deal with Montreal . . .

Dick Moss, the agent for center fielder Brett Butler, said he's still skeptical that baseball's free-agent market had opened up again. Moss expressed those opinions a day after negotiating the contract that moved Butler from the Cleveland Indians to the San Francisco Giants, the first time in almost three years a player has switched teams because of competitive bidding.

"It's too early to tell," Moss said. "The Butler thing may be one of those few cases that was done for show. I was encouraged that {Giants General Manager} Al Rosen came forward and vigorously pursued it, but a couple of things were disquieting. All the other clubs seemed to know what offers San Francisco was making and when they were made and what offers Cleveland was making and when they were made. That's the kind of information that can only be exchanged improperly." . . .
