The second half of the 2017 MLB season begins tomorrow. Based on past history, that may be good news for the Chicago Cubs and bad news for the Milwaukee Brewers.
In the last three seasons, the Cubs have had the best cumulative record over the second half of the season. They were 133-83 (.616 winning percentage) after the All-Star break from 2014-16. The Brewers, the team ahead of the Cubs in the standings, on the other hand, were .94-119 (.441 winning percentage) after the All-Star break from 2014-16. That ranked 24th of the 30 MLB teams.
The N.L. West-leading Dodgers, who have the majors best record this season, had the second best record after the break the last three seasons… they were 121-87 (.582).
Of the other four teams currently leading their division, the Washington Nationals ranked fifth in second half winning percentage the last three years, the Cleveland Indians ranked sixth, the Red Sox ranked 15th, and the Houston Astros ranked 17th.
