Looking to even the series, Pittsburgh manager Danny Murtaugh gave the ball to his promising rookie southpaw John Candelaria (2.76 ERA). Oakland skipper Alvin Dark turned to veteran hurler Sonny Siebert (3.90 ERA) to start Game 4.
The A's struck early when Joe Rudi clubbed a solo homer in the top of the first. Pittsburgh answered in the bottom of the third after Rennie Stennett doubled and then scored when A's second baseman Phil Garner misplayed an Al Oliver grounder that rolled into the outfield. The game remained knotted 1-1 into the bottom of the seventh. Richie Hebner led off that frame with a double and, following a strikeout, advanced to third on a double by pinch hitter Bill Robinson. Stennett singled to drive in Hebner and Oliver sent Robinson home with a sacrifice fly. Reliever Kent Tekulve took over for the Candy Man in the top of the eighth and retired six straight batters to close out the Pirates victory.
The series will return to Three Rivers Stadium for Game 5.
