How are these for splits:
Alex Gordon pre-2010: 334 games, .246/.330/.407, 37 home runs, 28 stolen bases, 5.1 WAR
Alex Gordon 2010-2012: 386 games, .271/.353/.437, 45 home runs, 28 stolen bases, 12.4 WAR
2010 was of course the season in which Ned Yost took over after 35 games.
For a long time Alex Gordon was heralded as a franchise player. Before Yost, it never showed. But since taking over, he's made it a priority to get Gordon comfortable in the lineup and the batters box.
I don't know if it's purely because of the managing change that Gordon has taken off, but better to not jinx things moving forward.
