25th Year:
Spring 2023 marks the 25th year in which WhoWins™ has been providing historical victory probabilities, team performance records, and web-site design from the previous millennium on MLB/NBA/NHL best-of-7 playoff series and games. Our first archived web page, from 1999.

2023 MLB Redux:
The 2023 best-of-7 MLB playoff season required 19 games to crown a champion, up from 15 in 2022 but down from 20 in 2020. Since the MLB adopted the format of two best-of-7 playoff rounds in 1985, the most games in a best-of-7 MLB playoff season have been 20 (in 2020, 2003, 1986, and 1985), while the fewest games in a best-of-7 MLB playoff season have been 14 (in 1990 and in 1989).

2023 NHL Redux:
The 2023 best-of-7 NHL playoff season required 88 games to crown a champion, down from 89 in 2022 but up from 84 in 2021. Since the NHL adopted the format of four best-of-7 playoff rounds in 1987, the most games in a best-of-7 NHL playoff season have been 93 (in 2014), while the fewest games in a best-of-7 NHL playoff season have been 81 (in 1995 and in 2007).

2023 NBA Redux:
The 2023 best-of-7 NBA playoff season required 84 games to crown a champion, the fewest since 83 in 2020. Since the NBA adopted the format of four best-of-7 playoff rounds in 2003, the most total games in a best-of-7 NBA playoff season have been 89 (in 2006 and in 2014), while the least have been 79 (in 2007 and in 2017). The Denver Nuggets required 20 best-of-7 NBA playoff games in 2023 to win the 2023 NBA championship, the fewest since the Golden State Warriors won the 2017 NBA championship in 17 best-of-7 NBA playoff games.

Comeback of Fall 2023:
On Friday 20 October 2023, the Houston Astros trailed their host Texas Rangers by two runs after 7.5 innings of their 2023 ALCS Game 5, but emerged victorious. In the history of best-of-7 MLB playoff games from 1905 through 2022, inclusive, road teams down two runs as late as after 7.5 innings had a game record of only 6-98 (.058) - the Houston Astros thus achieve a grade-A in-game comeback (.000-.099) in 2023 ALCS Game 5.

Comeback of Spring 2023:
On Monday 24 April 2023, on Spring 2023 Day 10, the Toronto Maple Leafs trailed the host Tampa Bay Lightning by three goals as late as 9:43 into the third period, but won in overtime. In the history of best-of-7 NHL playoff games from 1939 through 2022, inclusive, road teams down three goals as late as 9:43 into the third period had a game record of only 1-332 (.003). The Toronto Maple Leafs thus achieve a grade-A in-game comeback. The sole previous victory by a road team in that situation was tallied by the St. Louis Blues, which trailed the Kings in Los Angeles by three goals as late as 9:58 into the third period of series 755 Game 3 (in the 1998 NHL Preliminary round), but tallied four goals at 9:59, 11:03, 11:59, and 13:06 into the third period to record a 4-goals-3 comeback victory over the host Kings.
