The Mets leaned on Robertson's experience in the ninth inning after closer Edwin Diaz went down during the World Baseball Classic. The veteran reliever was outstanding for New York, compiling a 2.05 ERA and 1.00 WHIP over 44 innings, with 14 saves, seven holds and four wins. His strong first-half was attractive to playoff-contending clubs and he landed in Miami via mid-season trade. However, Robertson's performance fell off with his new team and he was removed from closing duties after blowing three of seven save opportunities with the Marlins. The veteran still finished the year with 18 saves, 10 holds and solid ratios, so it's clear he can still be effective with his arsenal. That said, with Robertson's age-39 season upcoming, the free-agent's market may be somewhat limited. Read Past Outlooks
