Profile: Gonzalez has been in a slow and steady decline since his spectacular 2012 season. The gap between his fastball and changeup velocities has steadily narrowed, from 10 mph in 2014, 8 mph in 2015, and now only 7 mph in 2016. Towards the later part of the season it was even nearing 6 mph. The vertical and horizontal movements are converging as well. These factors are turning his changeup into something more akin to a slow fastball. Isolated power against both his fastball and changeup are the highest they have been since 2009—he became a full time starter in 2010. Gonzalez’s HR/FB and ERA have each reached full season highs as well. SwStrk% (9%) and K% (22%) are still viable, though, so he should be able to wrack up a good number of strikeouts along the way. Unfortunately, his hard hit rate has been steadily increasing although his exit velocity only saw a modest increase between 2015 and 2016, and remains roughly league average. (Andrew Perpetua)

The Quick Opinion: Losing separation between his fastball and change-up is a bit scary, although it could be corrected through mechanical adjustments. His strikeout totals are enough to make him a viable back end starter, but the overall downward trend is worrying.
