Major League Baseball and the MLB Players Association have moved the deadline for a new collective bargaining agreement that would save regular season games from being canceled to Tuesday at 5 p.m. EST.

The two sides engaged in a 16-hour day of meetings on Monday that stretched into early Tuesday morning.

While the sides made progress toward a new deal during the marathon negotiating session, which included more than a dozen meetings and ended around 2:30 a.m. EST, gaps remain between the sides on the competitive-balance tax thresholds, minimum salary and bonus pool for pre-arbitration player, sources said.
