Only five American League teams finished at or above .500
The only American League teams that finished the regular season with winning percentages of .500 or higher are the five A.L. teams that qualified for the playoffs, all of which had winning records (the Indians, Astros, Red Sox, Yankees and Twins). It is the first time that either the American or National League had as few as five teams finish a season with as many or more wins than losses since the major leagues expanded to 30 teams in 1998.
Every major-league manager went “wire-to-wire” this season
Brad Ausmus will not be returning as the Tigers’ manager in 2018, nor will Pete Mackanin for the Phillies, and although their fates were sealed earlier last week, they both finished the season for their respective teams. Terry Collins announced his resignation as the Mets’ manager after Sunday’s season finale. Every major-league manager who began the 2017 season spent the entire season in that position. There have been only two other seasons over the last 75 years in which the manager of every major-league team went “wire-to-wire” in that position: 2000 and 2006.
Nothing new as the American League best the National League in interleague play
