Dick Kelley and Tom Seaver squared off in the opener. The Padres took a 2-0 lead in the second on a one-out Nate Colbert walk followed by a two-out Cito Gaston home run.
The Mets tied the score in the fourth, on the exact same sequence that plated San Diego’s runs. Tommy Agee drew a one-out walk, and Donn Clendenon drilled a two-out homer.
In the sixth, with Tommie Sisk now pitching for the Padres, added two more on two singles and a double. The Mets extended their lead to 8-2 the next inning against relievers Gary Ross and Dave Roberts.
San Diego got two of those runs back in the bottom of the seventh. Ollie Brown led off with his 16th home run of the season. Then, with two outs, Gaston tripled home Van Kelly to make the score 8-4, which was the final.
Seaver wasn’t his usual brilliant self but went the distance for his 18th victory. Sisk took the loss, dropping his record to 0-9 on the year. Sisk also had lost the Padres’ previous game on Sunday in Montreal as a starter.
The second game featured Joe Niekro and Jim McAndrew. The Mets had a chance to open the scoring in the third, loading the bases with one out, but came away empty.
In the sixth, New York broke through on three singles on a walk to take a 1-0 lead. The Mets added single runs in the seventh and ninth innings to make the final score 3-0.
McAndrew, for his part, dominated the Padres, scattering five hits and walking none in a complete game victory. The Mets had swept the doubleheader without using a single reliever.
