CINCINNATI -- After it was learned that a Reds player tested positive for COVID-19, Major League Baseball postponed the final two games of Cincinnati's series vs. the Pirates for Saturday and Sunday.

It has not been revealed which Cincinnati player tested positive. Both teams have off days on Monday for possible makeup games, but no dates have been announced to complete the games.

MLB said the postponements were made to allow for further testing and to complete the contact tracing process.

The Reds were scheduled to have Trevor Bauer start on Saturday with Luis Castillo on the mound Sunday.

Infielder/designated hitter Matt Davidson was the last Reds player to test positive for COVID-19 and he was placed on the injured list July 25 after his pre-Opening Day test was revealed. Davidson tested negative upon follow-up tests.

In the days that followed, Reds players Mike Moustakas, Nick Senzel and Joey Votto missed games upon reporting not feeling well and entered the health and safety protocol. None of them tested positive for the coronavirus, however.

Until Saturday, Cincinnati was the lone National League Central team to not have COVID-19 related postponements.

The Pirates previously had three games in St. Louis postponed last week. They would have had Steven Brault and Derek Holland pitching this weekend.
