Four more members of the Miami Marlins have tested positive for the coronavirus after the latest round of testing, sources familiar with the situation confirmed to ESPN.

The Marlins have now had 17 people test positive in the past five days. On Monday, the total of confirmed cases stood at 11 players and two coaches.

A majority of Washington Nationals players have voted against traveling to Miami for this weekend's three-game series against the Marlins, sources confirmed to ESPN. However, the decision on whether the games are played rests with Major League Baseball, not the Nationals.

News of the latest positive tests and the Nationals' vote was first reported by The Athletic.

The Marlins' outbreak continued to disrupt MLB's schedule Tuesday, the sixth day of the pandemic-delayed season, with the Marlins' home game against Baltimore postponed.

Monday's game between the Marlins and Orioles was also called off, as were the New York Yankees' games Monday and Tuesday at Philadelphia, where New York would have been in the same clubhouse Miami used over the weekend.

The Orioles, who made a trip to Miami without playing a game, are scheduled to host the Marlins in a two-game series starting Wednesday.

The Marlins placed infielder Garrett Cooper, outfielder Harold Ramirez and right-hander Jose Urena on the injured list. They claimed right-hander Justin Shafer and left-hander Josh Smith off waivers from Cincinnati, and they will likely rely heavily on reinforcements from their training camp in Jupiter, Florida.

MLB commissioner Rob Manfred told MLB Network on Monday that there are factors that would force MLB to alter plans.

"A team losing a number of players that rendered it completely noncompetitive would be an issue that we would have to address and have to think about making a change," he said. "Whether that was shutting down a part of the season, the whole season, that depends on the circumstances. Same thing with respect to leaguewide. You get to a certain point leaguewide where it does become a health threat, and we certainly would shut down at that point."
