The flamethrowing Ellington logged significant innings with the Marlins from 2015-17 (a combined 102 2/3) and adeptly prevented runs over his first two years, during which he compiled a 2.64 ERA. That figure came with less enticing peripherals, though, and Ellington crashed to earth last season. The 27-year-old recorded a 7.25 ERA/5.80 FIP with 9.67 K/9, 7.05 BB/9 and a 35.4 percent groundball rate across 44 2/3 innings. He then dealt with biceps tendinitis during spring training, leading the Marlins to send him to Triple-A to open 2018.
Now 25, Gonzalez was once a well-regarded prospect with the Phillies, who dealt him to the Marlins in a small trade over the winter. Gonzalez spent the 2017 season in the minors (mostly Double-A) and posted a 4.82 ERA with 6.3 K/9 and 1.9 BB/9 in 80 1/3 innings. He worked out of the Phillies’ bullpen from 2015-16 and yielded a 6.68 ERA across 66 frames, though he did manage strong strikeout and walk rates (8.45 K/9, 1.91 BB/9).
