Baseball's top labor lawyer said he believes there's a way to work out a new contract without another strike.
Sounding unusually optimistic, Rob Manfred said after Thursday's five-hour bargaining session that the sides will meet again today and probably have sessions for five straight days starting Monday.
That would be the longest period of sustained talks since the contract expired Nov. 7.
"I have said repeatedly, publicly, that I believe it is possible for us to reach a negotiated agreement without having an interruption of the season, and I still believe that," said Manfred, the executive vice president for labor relations.
Players, fearful owners will change work rules after the season or lock them out, are threatening to strike in August or September.
Meanwhile, nine public agencies that own stadiums released a statement urging Major League Baseball and the union to come to terms quickly and avoid a damaging strike.
St. Petersburg and city development administrator Rick Mussett are on the list. The city owns Tropicana Field and leases it to the Rays.
"The public has invested considerable money over the last decade" to build and renovate ballparks, the statement says. "This history demonstrates a clear statement of support and commitment by the public to the game. We ask that the owners and players reciprocate, respect this commitment and settle their differences without disrupting the game."
UMPS IRATE: Umpires threatened more legal action against owners over management's insistence that union representatives leave dressing rooms 30 minutes before games begin.
Union lawyer Larry Gibson said owners violated the labor contract by setting the time limit and by threatening to remove union representatives from ballparks and revoke their credentials if they violate the time limit.
