"It's just a disaster for our game, absolutely no question about it. It shouldn't be happening, and it's important that we find a way to get past it and get the game back on the field for the benefit of our fans," Manfred said.
The commissioner has reversed course after saying on ESPN during Wednesday's telecast of the MLB Draft that "unequivocally we are going to play Major League Baseball this year."

The MLB Players' Association emphatically rejected the league's latest proposal on Saturday, which would have put in place a 72-game regular season with players getting a guaranteed 70 percent of their prorated salaries. MLBPA executive director Tony Clark wrote in a statement that "it unfortunately appears that further dialogue with the league would be futile. It's time to get back to work. Tell us when and where."
