Seaver's impact was heavy as he led a staff that boasted excellent pitching, including then prospect Nolan Ryan in 1969. Perennial losers, the Mets came back to win the division and face off against the Braves in the NLCS. The "Miracle Mets" swept the Braves in the series, en route to their first World Series championship against the Baltimore Orioles in the 1969 World Series. The series against the Braves was the first playoff appearance and series win by an expansion team and their World Series win by extension was the first won by an expansion team.
