On May 6, 2012 — Albert Pujols finally hits his first American League homer, breaking the longest homerless drought of his career, when he connects off the Blue Jays’ Drew Hutchison with a runner on in the 5th inning of the Angels’ 4 – 3 win. Pujols was being regularly booed for his lack of offensive production after signing a huge contract to join the Halos as a free agent in the off-season.
