NOTE: THE url at the top in your browser will say "2012-2019". Please ignore that as we changed it to 2013-2019 to account for the Houston switching leagues so this is really 2013-2019.
Please see the disclaimer and source of the data here before reading:
Our Criteria here: Win - a given team is losing or tied at the start of the 7th inning and ends up winning the game. Loss - a given team is winning or tied at the start of the 7th inning but loses the game. How to read the results:
ZScore: is based on the population standard deviation and mean here. It tells you how many standard deviations from the mean you are. For wins, a positive ZScore is what you want as that relfects "you came back to win more than others". So 1.5 is better than 0.5. For the loss, a negative ZScore is what you want as that reflects "you did not lose your leads like others around the mean". So -1.5 is better than -0.5
"Which team in the AL had the BEST improvement between the first half of the season and the second half of the season between 2013 and 2019? In other words, from 2013 thru 2019, which team had the biggest difference between wins (tied or losing starting the 7th) in the first and wins (tied or losing starting the 7th) in the second half?". A positive value indicates the team did better. A negative value, the team did worse.
From July to the end of regular season:
The best team: Texas Rangers have a zscore of 1.42
The worst team: the Houston Astros have a zscore of -2.05
Second Half Improvement over First Half Won / Loss spread:
The best team: Texas Rangers zscore of 1.538
The worst team: the Cleveland Indians have a zscore of -1.658
If you want to see the significance again of the ZScore and what it can be telling you, please see:
The difference in won loss spread ((late inn win)-(late inn loss)) between 1st/2nd half of season.
ZScore (late inn win and losses) between 1st/2nd half of season. Positive value means "better in the 2nd half".
Totals between first and 2nd half of season
The actual won/loss spread (2nd half - 1st half). Positive value means they did better in the 2nd half.
