BALTIMORE (WJZ) — The long ball is alive and well in baseball.

In the first month of baseball, players had already whacked 863 home runs (the second most ever in April). The 2017 is tied for first with 2000 in home runs per game. A total of 5,610 home runs were hit in 2016, which was the second most in baseball history. That total was bested only in 2000, at the height of performance enhancing drug use by players. MLB is on a historic home run pace in this 2017 season.

Another reason is that in the last ten years, 4 out of 5 new stadiums have been built with shorter walls.
