ANGELS NOTEBOOK: COLLINS QUIETS TRADE RUMORS.

Byline: Marc J. Spears Daily News Staff Writer

All the trade talk about Oakland's Mark McGwire has put some strain on the Angels clubhouse.

On Saturday, Angels manager Terry Collins said he spoke with concerned outfielders Garret Anderson and Jim Edmonds on Friday. And after Friday night's game, Collins spent time listening to a McGwire update on television before speaking to the media. The A's power hitter will be a free agent at the end of the season and likely will be traded before the July 31 deadline.

Collins, however, believes it could be worse.

``If there is a distraction, it would be in the other clubhouse,'' Collins said. ``Everyone there is talking about that guy being traded. There is no one in our clubhouse that (the media) talks about on a daily basis being trading. There is no validity here, but there is over there.

``(Trade rumors) are all part of the business. You deal with it, move on and don't worry about it unless it actually happens.''

Langston hopeful: The Angels' Mark Langston pitched off the mound Friday for the third time since undergoing May 27 arthroscopic surgery on his left elbow. The left-hander, who has been on the disabled list since May 20, was originally supposed to work out Saturday, but he moved up a day because his arm felt well.

Langston wants a rehab start around July 21 and return to game action by Aug. 1. On Friday, he threw for 10 minutes, three more than previously. The 36-year-old also plans to pitch again either today or Monday, throw more sinkers and begin throwing breaking balls.

``I need to know if I'm pitching,'' Langston said. ``The team and I need to know either way. I'm going to step up everything.''

Collins said that Angels pitcher Mark Gubicza will begin throwing next week. The right-hander has been on the disabled list since April 12 and has missed 80 games. In two early games, he is 0-1 with a 25.07 ERA.

Parker honored: This morning, Angels first-base coach Dave Parker joins some of his former Oakland teammates during a Q&A session with the Athletics' 30th Anniversary Team that will give fans the chance to ask questions. Parker, who played in Oakland from 1988-89, was named the club's all-time designated hitter. Also expected to be on the panel are ex-Athletics Bert Campaneris, Carney Lansford, Dave Stewart, Gene Tenace, Dave Henderson and Ray Fosse.

``We had some good years here,'' said Parker, who played in two World Series with the A's and won a championship in 1989. ``Some fun teams. Guys checked their egos at the door and we genuinely liked each other. That is unique in this game. Those are probably the fondest two of my 19-year career.''
