Major League Baseball negotiations moved to the verge of a breakdown after taking several steps forward Saturday, leaving less than two days until management's deadline for an agreement to salvage Opening Day on March 31 and a 162-game schedule.

While the sides moved toward each other on some topics as they negotiated for the sixth straight day, they remained far apart on the biggest economic issues: luxury tax thresholds and rates, the minimum salary and the new pre-arbitration bonus pool.

Players were angered by the state of negotiations but after some discussion agreed to meet with the league again on Sunday for a seventh straight day.
