The 23-year-old Hanhold, Milwaukee’s fifth-round selection out of the University of Florida in 2015, spent the 2017 campaign pitching for the Brewers’ Class-A Advanced affiliate. In 30 appearances (three starts, 27 out of the bullpen), he totaled 64 innings with a 3.94 ERA, 8.4 K/9, 3.0 BB/9 and a whopping 58.6 percent ground-ball rate. Hanhold didn’t rank among the top 30 prospects in a deep Brewers farm system (per MLB.com), but Baseball America wrote at the time of the draft that he featured a 90-94 mph heater that could touch 95 with downhill plane and heavy sink (subscription required and recommended). His go-to breaking pitch is a slider, per that report, though he also broke into pro ball utilizing a changeup as a third pitch.
Hanhold continues a trend for the Mets, who have turned a number of veteran free agent on expiring contracts to a crop of fairly hard-throwing relief prospects that are reasonably close to Major League readiness. Right-handers Jamie Callahan and Jacob Rhame, acquired in the respective Addison Reed and Curtis Granderson trades, have already been added to the big league roster. In addition to Hanhold, Callahan and Rhame, the Mets have added minor league relievers Drew Smith, Stephen Nogosek, Gerson Bautista and Ryder Ryan in trades of Walker, Granderson, Reed, Lucas Duda and Jay Bruce.
To this point, the trade has paid dividends for the Brewers, as Walker has .268/.388/.465 with three home runs and five doubles through his first 85 plate appearances in a Milwaukee uniform.
