Pittsburgh Pirates third base prospect Ke'Bryan Hayes is out indefinitely while dealing with the novel coronavirus.
Manager Derek Shelton announced Hayes' illness on Sunday after the 23-year-old Hayes -- the son of former longtime MLB third baseman Charlie Hayes -- gave the team clearance to do so.
The diagnosis blunts the momentum that Hayes, considered the top infield prospect within the organization, built during spring training.
The Pirates expected Hayes, a three-time Gold Glove winner while in the minors, to make his MLB debut this season while splitting time with Colin Moran.
