Kelvin Herrera (RHP): Herrera is one of the few all-star relievers available on the free agent market this season. A fireballer, Herrera won a World Series ring with the Kansas City Royals in 2015, making back-to-back AL all-star squads in 2015 and 2016. Last season, the Royals dealt Herrera before the trade deadline to the Washington Nationals. Herrera had injury problems last season so he only threw 44.1 innings, finishing up the year with a 2.44 ERA and a 92.1% strand rate.
He was much better in his role as the Royals closer in comparison to his late-inning relief role for the Nats, as he had a 1.05 ERA and .70 walks per nine innings with Kansas City versus a 4.34 ERA and a 3.86 BB/9 once in D.C. Herrera’s diminished performance last season should drive down his price to a point, and his playoff experience and skill set is unmatched at his price point, which will probably be around $8 million per season.
