What to Expect from Marwin Gonzalez

Rafe Anderson

Twins Daily, part of ESPN’s SweetSpot Network, uses TruMedia’s site to explore what to expect from Minnesota signing Marwin Gonzalez this season:

“While the changes to his swing have led to an improved approach and more consistent contact, the baseball gods seemingly looked the other way in 2018 after showering him with good fortune in 2017.

His average exit velocity dropped to his normal levels. After posting a 92.1 mph exit velocity in 2017, it receded back to 90 mph in 2018. The second data point that changed is his average launch angle increased from 9 degrees to 14 degrees. Most may consider an increase in launch angle a good thing but for Gonzalez, it led to more batted ball outs -- specifically in the line drive category.

Per ESPN/TruMedia’s data, in 2017, Gonzalez had a .794 batting average on line drives as a lefty. Coincidentally, only Logan Morrison (.805) had a better average. The rest of the league’s left-handed constituency sat at .687. So Gonzalez was performing well above the norm which may have been an indication to expect regression. Last year that number dropped to .613. Part of the reason for this is that his line drives carried a bit further than his previous season. In 2017 his average liner went 257 feet on average but was at 268 feet in 2018, meaning fewer liners dropped in front of the outfielders and infielders. Hitting the ball hard on a line is obviously preferential, however there are some diminishing returns when more liners become midrange instead of short or long.”
