SERIES NOTES:
After Game 2: The Kansas City Royals hosted and defeated the
Toronto Blue Jays 6-runs-3 to take a best-of-7 MLB/NBA/NHL playoff
series 1284 lead of 2-games-nil. When leading a best-of-7 MLB/NBA/NHL
playoff series 2-games-nil, the Kansas City Royals have a series record
of 1-0 and a Game 3 record of 1-0. When trailing a best-of-7 MLB/NBA/NHL
playoff series 2-games-nil, the Toronto Blue Jays have a series record
of 0-1 and a Game 3 record of 1-0. Kansas City trailed Toronto by three
runs after 6.5 innings of series 1284 Game 2. In the history of
best-of-7 format MLB playoff games from 1905 through series 1284 Game 1,
home teams trailing by three runs after the top of the seventh inning
had a game record of only 7-44 (.137) overall and 2-17 (.105) in the MLB
Semifinals. The two previous home-team MLB Semifinals game winners in
this situation were the St. Louis Cardinals (hosting the Atlanta Braves
in series 721 Game 4, in the 1996 National League Championship Series)
and the New York Yankees (hosting the Boston Red Sox in series 903 Game
7, in the 2003 American League Championship Series). With an MLB-topping
best-of-7 format Semifinals-round game-winning streak now at nine
games, the Kansas City Royals (1985, 2014-15) match multi-year best-of-7
format Semifinals-round game-winning streaks of the NBA Los Angeles
Lakers (1980, 1982-83) and Chicago Bulls (1993, 1996-97) and the NHL
Detroit Red Wings (1954-56), Montreal Canadiens (1957-59 and 1965-67),
New York Islanders (1980-82), and Edmonton Oilers (1983-85). The longest
MLB/NBA/NHL multi-year best-of-7 format Semifinals-round game-winning
streak is 13, by the 1965-68 Montreal Canadiens as the extension of the
aforementioned Montreal nine-game streak.
