The Royals made a few moves on Thursday, adding right-handers Greg Holland and Tyler Zuber, infielder/outfielder Erick Mejia and catcher Oscar Hernandez to their roster.
Holland is the only member of the quartet with significant major league experience, and he has thrived at times, as shown by his three All-Star nods in Kansas City from 2010-15. He threw 319 2/3 innings of 2.42 ERA/2.23 FIP ball with 12.11 K/9 and 3.52 BB/9 during that span, but August 2015 Tommy John surgery stopped Holland from contributing to the Royals’ World Series-winning run late that year and has knocked his career off course in the ensuing seasons.
Since he underwent his TJ procedure, Holland has recorded a 4.20 ERA/4.02 FIP with 10.21 K/9 and 5.3 BB/9 over 139 1/3 innings as a Rockie, National, Cardinal and Diamondback. But the the former lights-out closer will get a chance to revive his career with the Royals, who signed him to a minor league contract in the offseason.
Zuber, 25, ranked as FanGraphs’ 13th-best Royals prospect in April. The 2017 sixth-round pick climbed to the Double-A level for the first time last season and pitched to a 2.42 ERA/2.95 FIP with 10.38 K/9 and 1.73 BB/9 in 26 innings. Also 25, Mejia saw a bit of major league action last year in KC, but the overwhelming majority of his work came in Triple-A, where he hit .271/.339/.382 in 556 plate appearances. Hernandez, whom the Royals signed to a minor league pact earlier this month, appeared briefly with the Diamondbacks from 2015-16. He batted a paltry .209/.274/.399 in 168 PA last season with Boston’s Triple-A affiliate.
