They held a clubhouse meeting to discuss whether a teammate was stealing their money. Their owner said he was going to start making more baseball decisions. And they hired a batting coach just for left-handed hitters.

That was the week that was with the New York Yankees.

They continue to rip through the American League East and look as if they might win 110 games, but, even if they do, the ride won't be a smooth one. Their biggest worry is leadoff man Rickey Henderson's sore shoulder, the one that limited him to serving as designated hitter three games this week and the one that apparently prevents him from hitting home runs.

But with the Yankees, there's always a subplot, and the most interesting one this week concerns the fact that several players have had money stolen in different cities.

Gary Ward had $1,400 taken from his clothes during spring training, Manager Lou Piniella had $1,300 taken during a game in Anaheim, Calif., and Don Mattingly and Mike Pagliarulo lost about $550 between them in Seattle.

All the thefts apparently have occurred during games, and a clubhouse meeting was called last week to discuss it. No conclusions were reached or suspects named.

This week, Yankees Owner George Steinbrenner hired former Yankees great Bobby Murcer to coach left-handed hitters. He'll probably share a locker with Hoyt Wilhelm, the part-time knuckleball coach.'I Get the Blame'

And Steinbrenner was so unhappy about Ron Guidry's debut, he said, "Clyde King {Yankees scout} said he was ready. You could see Wednesday night he wasn't. From now on, I'll make the decisions. If they don't work out, I get the blame, anyway . . . "

Steinbrenner also has refused to let pitching coach Mark Connor accept a job as University of Tennessee baseball coach, although he's fired Connor twice in the past . . . The other team in New York, the Mets, also has its share of problems. Every starting pitcher except Ron Darling has missed at least one start because of injury, and it appears the team's starting rotation will have John Mitchell, Terry Leach and/or Don Schulze in it for at least a couple of months. Dwight Gooden will return Friday, but reports from the minors are that he looks very hittable.

The Mets also are concerned about Gary Carter, who appears to be showing the strain of having caught 1,500 games. Entering the weekend, he led the National League in grounding into double plays (nine), his average had slipped into the .230s and he had thrown out only 14 of 49 base runners (29 percent). The Mets apparently have considered shifting him to the outfield, but they don't have another catcher . . .

Toronto's Dave Stieb, saying he has become a born-again Christian, also believes he has corrected a mechanical problem, bringing the pop back to his fastball. Since the conversion, he actually has been seeking out advice, whereas he once wouldn't listen to anyone. However, scouts still wonder about his arm, especially since he's throwing so many breaking pitches . . .

Los Angeles Dodgers Manager Tommy Lasorda called a clubhouse meeting to air complaints and needed 130 curse words to get through it. How does anyone know that? Coach Bill Russell said he kept count on the little device used to count pitches . . . With Bill Madlock gone, the Dodgers are considering some weird infield combinations, even having second baseman Steve Sax take ground balls at third. Shortstop Mariano Duncan could be moved to second and Dave Anderson put back at shortstop.

At the moment, however, Lasorda is so down on Duncan he may not be playing anywhere. He entered the weekend in a three-for-39 slump, apparently because he has tried to become a home-run hitter. Lasorda has begun removing him from batting practice every time he hits a ball in the air . . .

Have the St. Louis Cardinals turned their season around? They scored five or more runs in 25 of their first 43 games. Over the same stretch last year, they had scored three or fewer 25 times. The main reason is first baseman Jack Clark, who already has more RBI this month (35) than all of last year (12). "He makes the rest of it flow," Cardinals Manager Whitey Herzog said.

They have hit 32 homers in their first 43 games, and a year ago didn't get their 32nd until July 28.

The Cardinals are even going so good that reliever Bill Dawley got a victory this week, his first since Oct. 2, 1985. He had lost 11 straight decisions in relief, and that's believed to be an all-time record . . . Of the Mets, Herzog said, "You can hardly call them a dynasty when they have Howard Johnson and Rafael Santana on the left side of their infield." . . . The Philadelphia Phillies' return home next week ought to be interesting. In an interview last week, new catcher Lance Parrish referred to Phillies fans as "idiots."Revamped Wrigley

It now appears a radical facelifting of Wrigley Field is inevitable, and it will include lights, 40 sky boxes, 10,000 additional seats and upper-deck concession areas and restaurants. Neighborhood opposition is still there, but proponents of the plan believe it will pass . . . The Chicago White Sox believed getting Harold Baines back would make a tremendous difference, and it has shown up in the statistics of the people hitting around him.

Gary Redus, who hits just in front of Baines, batted .179 while Baines was out but has batted .339 since his return. Greg Walker, who hits just behind Baines, hit .205 in Baines' absence, .288 since his return . . . The imperfect matchup: The White Sox are 3-0 versus Roger Clemens the last two years . . .

More news from the San Diego Padres: Their pitchers are on a pace to allow 213 homers, and the club is on a pace for the worst record ever (37-125). The San Diego staff allowed a home run to Greg Gross, his first in 1,618 at-bats. They're also the team that allowed Bob Melvin and Luis Aguayo three-homer games. And attendance is down 29 percent . . . The Kansas City Royals have never had a better 43-game start than their 26-17 this year. They're also 20-12 without George Brett . . .

The imperfect matchup, part 2: Remember how Tim Raines wanted to play for the Dodgers? This year, he's getting the next-best thing. He has gone 10 for 25 with seven homers and three RBI against them, as the Expos have won five of the six meetings . . . No one can say the Cleveland Indians are a one-man team. They're a two-man team: Entering the weekend, Julio Franco and Pat Tabler had driven in or scored 104 of their 188 runs.
