Season standings
This was the first season since 1904 that the Yankees finished second in the standings to the Red Sox. Then, the Yankees were known as the Highlanders and the Red Sox were the Americans.

Billy Martin
On August 10, 1986, the Yankees retired Martin's uniform number 1 and dedicated a plaque in his honor for Monument Park at Yankee Stadium. The plaque contains the words, There has never been a greater competitor than Billy. Martin told the crowd, "I may not have been the greatest Yankee to put on the uniform, but I am the proudest."

On May 24, 1986, on the season finale of Saturday Night Live, co-host Martin was "fired" by executive producer Lorne Michaels for being "drunk" in a skit, slurring his lines. During the goodnights, Martin "sets fire" to the dressing room in retaliation. (Only three cast members would be re-hired the next season.) In 1988, on Saturday Night Live's Weekend Update, comedian Dennis Miller opened the sports with, "In Calgary tonight, Katarina Witt won the gold medal in figure skating, prompting Yankees owner George Steinbrenner to fire manager Billy Martin."
