Major League Baseball (MLB) seasons have always started well after January 1, and ended well before December 31. Thus, the record for the most runs in a season would also be the record for the most runs in a calendar year. That record was made in the National League in 1894, when William Robert "Sliding Billy" Hamilton scored 198 runs. He holds many other unbroken records, as well.
The Mets' most wins in the regular season is 108 (with 54 losses), in 1986. Including the postseason the Mets won 116 that year, which at the time stood as the highest total since the 1906 Cubs. This accomplishment is somewhat misleading (and therefore widely ignored). Before 1969 there was no League Championship Series, and in 1975 (when the Reds won 108 regular season games, the LCS, and the World Series) the LCS was a best of 5 series. The 1998 Yankees, with the benefit of 3 postseason rounds, managed a remarkable 125-50 record including the postseason. They went 114-48 in the regular season and 11-2 in the postseason.
