Back in Hartford for the third straight year, Pierpont was again terrific for the Yard Goats. The right-hander from Winthrop University saved 32 games in 34 chances in his first season as a closer -- twice as many as any other Top Reliever nominee -- while earning midseason and end-of-season Eastern League All-Star selections and posting the first sub-2.00 ERA of his career.

One of three Top Relief Pitcher nominees to have been traded during the 2018 season, Eveld put up a 1.07 ERA in 45 total outings in the Arizona and Miami systems.

In the midst of a spectacular season with Double-A Trenton in the Yankees system, Frare was shipped to the White Sox in July. There, he climbed to Triple-A and was even more formidable. With his new organization, the lefty put up a 0.71 ERA in 11 appearances, striking out 19 batters while walking seven and holding opponents to a .119 average.

Like Frare, Poche was dealt midseason, going from the D-backs to the Rays in May. A D-backs Organization All-Star last year, he was as dominant a reliever as any in baseball. The southpaw fanned 15 batters per nine innings, striking out 23 in 11 innings with Double-A Jackson in the Arizona system, nine in five frames with Double-A Montgomery after the trade and a jaw-dropping 78 in 50 innings with Triple-A Durham.

In his fourth season in the Rangers system, Evans broke out after moving to the bullpen full-time. The right-hander didn't allow a run over his final nine appearances and was scored upon in only seven outings all year. Evans fanned a jaw-dropping 16.6 batters per nine innings, the highest mark of any Top Relief Pitcher nominee in 2018.

A 14th-round pick in 2017, Warren dominated South Atlantic League hitters for Class A Lakewood in his first full season. The former Tennessee Volunteer posted a 0.68 ERA in 21 games after the SAL All-Star Break, striking out 56 batters in 26 innings, and notched 15 saves in 16 total opportunities.

Williams struggled at Double-A in 2016-17 but figured things out this year. After posting a 1.39 ERA in 24 outings for Double-A Harrisburg, he jumped to Syracuse and was even better, putting up a 0.55 mark in 16 1/3 innings. In total, the righty fanned 89 batters in 68 innings and limited opponents to a .166 average on the way to his September big league debut.
