Haddix has a 13 -- 8 record against the Redbirds, despite only a 1 -- 3 mark in 1960.

Pirate Manager Danny Murtaugh said he hadn't decided between Mizell and Vern Law for Wednesday's game. Mizell has won both of his starts.

After a lengthy workout yesterday, an open date, Hemus said that Bob Nieman definitely would stay in the lineup. That means Stan Musial probably will ride the bench on the seventh anniversary of his record five home run day against the Giants.

``I have to stay with Nieman for a while,'' Hemus said. ``Bill White (sore ankles) should be ready. With a lefthander going for Pittsburgh, I may use Don Taussig in center.''

``Lindy McDaniel threw batting practice about 25 minutes, and he looked good,'' Hemus said. ``He should be getting back in the groove before long. Our pitching is much better than it has shown.''

The statistics hardly indicated that the Pirates needed extra batting practice, but Murtaugh also turned his men loose at Busch Stadium yesterday.

Until the Bucs' bats quieted down a bit in Cincinnati over the weekend, the champions had eight men hitting over.300. Despite the recession, Pittsburgh came into town with this imposing list of averages: Smoky Burgess.455, Gino Cimoli.389, Bill Virdon.340, Bob Clemente and Dick Groat, each.323, Dick Stuart.306, Don Hoak.280 and Bob Skinner.267.

Bill Mazeroski with.179 and Hal Smith with.143 were the only Pirates dragging their feet.
