Rod Carew almost certainly is heading into his final year as a Minnesota Twin because Calvin Griffith has made clear to his batting champion the team is not interested in negotiating a long-term contract.

"There is no way I'm interested in signing a two-year contract with the Twins," said 12th-year Twin Carew after a meeting between his new agent, Jerry Simon, and Griffith in Orlando, Fla., resulted in only such an offer.

"I wanted to sign a contract that would commit me to the Twins for the next seven, eight years, for the rest of my career,' Carew stewed. Since they are not interested in that, the Twins should trade me. I'm considering something to force them to make that move. I hate to do something like that to Gene (Mauch, Minnesota manager) but what happened (after the Simon-Griffith talk) had me walking around in a daze at the clubhouse.

"I know I'm going to have trouble in my mental approach if I remain here, and I don't want to spend two seasons going through the motions."

Carew has one year left on a three-year contract, plus an option year to which he is obligated because he signed before the 1976 Players Association agreement. His agent is talking $500,000 a year (Carew currently earns $200,000 salary, and received a $100,000 bonus for his .388 feat last season. He'll be 33 on Oct. 1.

Griffith would seem to have little choice but to swing a trade sometime between now and say, June 1979, or see his star go in the autumn 1979 reentry draft. The Twins' only compensation that way would be an amateur draft choice, if we've got our rules straight . . .

Leon Spinks' lawyers say they'll be in federal court, Las Vegas, today suing the World Boxing Council for stripping their man's heavyweight title - they say in violation not only of antitrust laws but of WBC's own Article 12.

Interesting was the word yesterday from Almost Heaven that a very nearby ACC coach supposedly was interviewed for the West Virginia U. basketball job supposedly being filled with Gale Catlett of Cincinnati today, and so is the one from Atlanta (a la last week's from Indianapolis re the Purdue job) of Foster, Foster, Tacy and Holland of the ACC being "among top candidates" to coach at U. of Georgia - but that Florida State's Hugh Durham is "the top candidate" . . .
