Looking at his underlying stats the only things that really jump out to me are his walk rate and BABIP are significantly lower than previous years. Everything else (hard hit rate, barrel rate, K%) are all basically the same as his career norms.
Lower BABIP suggests less grounders, and sure enough his GB% is the lowest of his career and he's hitting more fly balls instead. I think he's pressing like Bell was to start the season to hit more homers and be a middle of the order power bat.
