re: Nick Markakis has joined the 2,000 hit club

In Markakis' third season, he hit 20 HRs, batter over .300, walked 99 times and led the American League in WAR. He never reached those heights again and I don't understand it. He was fairly healthy and there was no noticeable decline in his physical skills besides speed yet he just could never replicate what he was able to do during the early part of his career. His power steadily declined after his third season and he became a Punch and Judy hitter. It was puzzling to witness to say the least.
