Marwin Gonzalez made his big league debut with Houston in 2012 as a utility infielder. He spent most of his time trading time at shortstop with Jed Lowrie with occasional appearances at second and third base in 80 games. His plate appearances have continued to rise every year since then: 219, 222, 285, 344, 484 from 2012 to 2016 respectively.
As recently as three years ago Gonzalez was thought to be just above replacement level (.4 WAR in 2012 and 2013 combined), with his roster spot always facing contention from Jonathan Villar.
