October 7, 2010 – Twins take the lead, Yankees come back and win – same old script. The Yankees have won seven consecutive postseason games against the Twins, despite the Twins owning a lead in all seven games. That’s the longest such winning streak in postseason history. The next best belongs to the Indians, who won five straight games in that fashion against the Red Sox from 1998 to 1999.

October 9, 2010 – The bad news for Twins fans is that the team extended its postseason losing streak to 11 games on Thursday; the good news is that they cannot, this year, equal the major league record of consecutive postseason losses. The Red Sox lost 13 consecutive postseason games from 1986 to 1995, a streak that started with the Bill Buckner game.

The Twins did match 1 major-league record on Thursday night. The team that won World Series in both 1987 and 1991 by going a combined 8-0 at home has now lost its last 10 postseason home games (a streak that began in 2002); that ties the record set by the Phillies in a streak that lasted from 1915 to 1978 (or from Woodrow Wilson to Jimmy Carter).
