Thankfully This is the Last Year MLB Rosters Can Expand to 40 On September 1

Since the minor league seasons end in early September, the Major League teams are allowed to expand their rosters to 40 on September 1.  This allows managers to observe players who are being evaluated for promotions in the next season.  Managers have certainly more options with more players on the bench.  This means more pinch runners, defensive changes, and pitching changes.  I just hate it when a pitcher is brought in to face just one batter.  This happens more often in September which makes the games longer.

Thankfully, the rule will be changed in 2020 that will allow the rosters to be expanded only to 28 in September.  Also, a pitcher must face at least 3 batters or finish an inning.  Less pitching changes will create shorter games.
