DETROIT -- The Royals continue to list Wednesday’s starter as to-be-announced, and manager Ned Yost said Sunday he still wasn’t sure who that would be.

The options, Yost said, likely would include right-hander Scott Barlow, who is in the bullpen right now, or right-handers Heath Fillmyer, Arnaldo Hernandez, or Glenn Sparkman, all three at Triple-A Omaha.

Yost seemed to hint that it would be someone presently on the 40-man roster.

Fillmyer, who narrowly missed making the 25-man roster out of camp, did not have a good first start on Thursday with Omaha: four innings, seven hits, six runs, four walks.

Hernandez pitched on Friday and gave up one run over four innings.

Bullpen options

The Royals signed right-hander Drew Storen in the offseason to possibly help the bullpen. But Storen, who hasn’t pitched since late 2017 after undergoing Tommy John surgery, struggled with his velocity and command in camp.

Storen remains in extended spring training building up arm strength and wouldn’t appear particularly close to helping the Royals’ beleaguered bullpen anytime soon.

One name that could help might be Omaha right-hander Michael Ynoa, who had a strong camp. Ynoa is out of options, though, and not on the 40-man roster. The Royals do, however, have an open spot on the 40.

Schwindel’s first hit

Rookie first baseman Frank Schwindel got his first MLB hit on Saturday, a sharp grounder up the middle that just got past the shortstop. He was relieved to get that first hit over with.

“You know after that first game I thought I had a hit and they gave it an error,” Schwindel said. “So yeah, it’s a good feeling to get it out of the way.”

Schwindel spent much of Saturday night returning text messages and talking with family.
