Almost two thirds of the way through the month, April 2019 remains on pace to be a record setter for home runs in the expansion era. The record is 931 in the year 2000, the height of the PED era. The total is a little unfair, as April over the years varied in length. April 2000 also set the record for home runs per PA, 3.26. Through Friday, MLB is averaging 3.45 HR per PA, with 628 home runs hit in the month (note that this is strictly April, the March HR are not counted). There is an outside shot at 1000 HR this month. There have only been eight months with at least 1000 home runs, and six of those occurred in the 2016-2017 time span.
