Graig Nettles hit two home runs and Dave Winfield had another yesterday to help Ron Guidry and the New York Yankees to a 4-2 victory over the Milwaukee Brewers in Yankee Stadium. And Bob Lemon, in his second day as the latest manager, already was having problems with Reggie Jackson.

The Yankees are 2-0 under Lemon, who returned to New York for the first time as manager since replacing the fired Gene Michael on Sunday. The victory was the Yankees' fourth straight and ninth in their last 11 games. Lemon was greeted warmly by the crowd of more than 55,000.

"They say it's better the second time around," said Lemon, settling in for his second stint as Yankee manager. "That's what I expect it to be."

Bobby Brown replaced Jackson in right field in the eighth inning after Jackson became angry over his pitching teammates' failure to retaliate after he was knocked down three times by Randy Lerch of the Brewers.

Lemon would not say if he removed Jackson from the game or if Jackson asked to be taken out, but, according to several Yankee players, Jackson was furious.

Jackson apparently had asked Lemon to have Guidry retaliate. Before Guidry could throw a pitch in the top of the seventh, however, first base umpire Marty Springstead warned both the Milwaukee bench and Guidry that any pitch deemed to be a brushback pitch would result in an automatic ejection from the game.

Winfield hit his ninth homer in the first inning and Nettles homered after a second-inning single by Lou Piniella for a 3-0 lead. Nettles hit a homer, his 13th, in the fourth with none on. All three came off Milwaukee starter Randy Lerch (4-8).

Guidry (10-3) gained his fifth victory without a loss in six starts since the second season began, allowing three hits, including Robin Yount's ninth homer in the sixth, before being relieved by Ron Davis with two out in the seventh.
