Pujols has had very slow starts in April most of the time with the Angels.Slash lines in April from 2012-2016

2013: .252/.344/.417

2016: .176/.242/.385
I actually forgot that he had a cold bat in April 2015 because his numbers at the ASB that year were phenominal and he made his first All Star team as a Halo but nope, also started in April. I'm going to say he heats up as the year goes on though. At least he has hit a home run this month, unlike in April of 2012.
But one of these seasons though, he might not heat up as the year goes on. Age is a big reason for that. Eventually, he might put up a .220/.300/.380 slash line in a season and bring back the ugly memories of the Hamilton era.
