Singer was invited to the Royals' big-league spring training camp Monday, Jeffrey Flanagan of MLB.com reports.
The 18th overall pick in the 2018 draft, Singer made his professional debut last season, posting a 2.85 ERA in 26 starts at the High-A and Double-A levels. He's unlikely to break camp with the team but could be up at some point midseason if his start to the year in Triple-A goes well.
Singer has been promoted to Double-A Northwest Arkansas, Alec Lewis of The Athletic reports.
Singer began his 2019 campaign at High-A Wilmington, but he's earned a promotion after posting a 2.13 ERA and 1.16 WHIP with a 49:11 K:BB over 50.2 innings. After being selected in the first round of the 2018 first-year player draft out of Florida, Singer has fared well through his first nine starts in the minor leagues.
Singer will begin his pro career at High-A Wilmington, Sam Dykstra of MiLB.com reports.
Singer, who was selected with the 18th overall pick in last year's draft, was shut down after signing, given how much he'd pitched for Florida that year, so this represents his first assignment as a pro. He is not expected to need much minor-league seasoning and could reach the majors sometime in 2020.
