Bruce Kison, a longtime Pittsburgh pitcher who reentered as a California Angel last winter, has warmed the cockles of Buzzie Bavasi's heart by offering the Angel exec to refund some of his big salary because arm trouble made his 1980 season a dud.

"The youngster showed me a lot," Bavasi relates. "He said he hadn't been fair to us, that he hadn't lived up to our expectations, and wanted to come in and find a way to repay the club 'for the problems I've caused it.' I told him that if he won 20 or 30 games, we wouldn't tear up his contract and renegotiate, that we still expect four good years from him and the fact that he called is good enough for me."

Kison, 3-6 with 4.91 ERA, has decided to undergo surgery for inflamed nerves in his right elbow and wrist -- "I can't make a fist or open a bottle of pop," let alone pitch, said the 1971 World Series star turned by that untrustworthy arm into a 1979 Series bust. But not bust enough that the Angels didn't pony up about $2.4 million in a five-year contract. . .
