Jhoulys Chacin, Milwaukee Brewers
March/April Stats: 3-3 record with an 18.1% strikeout rate, 12.5% walk rate, 5.24 ERA, 5.54 SIERA, and -0.1 fWAR in 34.1 innings
Does Jhoulys Chacin being on this list feel familiar? Well, it’s because he was last year’s cover boy, owning the second-worst SIERA heading into May. He did himself one better this season by taking the top (or bottom?) spot. As we saw, though, the right-hander still went on to have himself a solid campaign.
In addition to the above peripherals, Chacin is also allowing 1.83 homers per nine innings, which would easily be a career-worst mark if the season ended today. Not surprisingly, this number has been fueled by a 46.5% fly-ball rate and 43.0% hard-hit rate allowed.
Although Milwaukee being home to a hitter-friendly park, Chacin has been much more stingy there than on the road (similar to what he did in 2017 with the San Diego Padres). In 16.1 innings at home, the righty has produced a 2.76 ERA despite that being paired with a 47.7% fly-ball rate and 50.0% hard-hit rate. In 18 innings on the road, his ERA is up at 7.50, with five of the seven total dingers he’s allowed coming in this scenario.
