The Royals have placed right-hander Jakob Junis on the 10-day disabled list with low back inflammation, per Maria Torres of the Kansas City Star. Additonally, the club selected the contract of righty Glenn Sparkman from Triple-A Omaha, giving Kansas City a full 40-man roster.
Junis had been scheduled to start the Royals’ game against the Red Sox on Sunday, but righty Heath Fillmyer will take the ball instead. Across 17 starts and 101 2/3 innings this season, the 25-year-old Junis has struggled to a 5.13 ERA/5.47 FIP, though he has managed 8.14 K/9 against 2.48 BB/9.
Fillmyer, 24, is now set to make his first big league start. He joined the Royals in an offseason trade with the Athletics and has made his first three major league appearances this year, throwing nine innings of two-run ball out of KC’s bullpen. He hasn’t fared nearly that well in 13 Triple-A starts, though, with a 5.75 ERA/4.62 FIP in 67 1/3 frames.
Sparkman is in position to see the second MLB action of his career. He tossed one inning in 2017 with the Blue Jays, who took him from the Royals in the 2016 Rule 5 draft but then returned him to Kansas City last July. The 26-year-old has divided this season between the minors’ two highest levels and combined for a 3.96 ERA with 6.2 K/9 against 1.1 BB/9 in 16 starts and 88 2/3 innings.
