We don’t, but he was still a good one.
In the season that he split between New York and Cincinnati, he had a year good enough to finish third in Cy Young voting while being named an All-Star that year and the following one. He would be an All-Star again in 1981 and would lead the National League in Wins in that strike-shortened year. Fittingly for Mets fans, he was traded back to them after the 1982 season.
WIth the Reds, Seaver had a record of 75-46 with a 3.18 ERA and 731 Strikeouts.
