What if Trumbo struggles early?

Los Angeles Angels slugger Mark Trumbo started 2012 with a bang. He batted .348 with a .396 on-base percentage through May, including 10 home runs. After that it was all down hill. Trumbo managed a paltry .237/.285/.434 with 118 strikeouts over the final 101 games he played. Which one is the real Trumbo?
