The Pirates avoided arbitration with Ledezma by coming to the early agreement. Financial details of the contract were not announced. The signing suggests that the organization sees Ledezma as part of its 2011 bullpen, which has a number of vacancies to fill this offseason.
Ledezma began the 2010 season in Triple-A, where he remained until being called up to Pittsburgh in late July. He allowed 25 hits and 15 earned runs in 19 2/3 innings with the Pirates.
In other notable moves, the Pirates outrighted five players -- Brandon Moss, Justin Thomas, Sean Gallagher, Steven Jackson and Jeff Clement -- to Triple-A Indianapolis.
Moss, Thomas and Jackson are all now immediately able to declare themselves Minor League free agents because each had previously been outrighted off a 40-man roster. None of the three has officially filed for free agency, though that is expected to happen soon.
Of the three, the departure of Moss will be the most disappointing for the Pirates, simply because the expectations for the outfielder were high when he was acquired as part of the Jason Bay trade in 2008. Moss never found his swing with Pittsburgh in '08, and lost his grip on a starting job during a tumultuous '09 season.
After clearing waivers during Spring Training, Moss spent the year with Indianapolis. There, he made some successful adjustments to his swing and ended up leading the International League with 96 RBIs. He played only minimally after being called up by the Pirates in September.
Even though Moss had a successful Triple-A campaign, the Pirates' decision to part ways with him wasn't surprising. He would have entered camp in February out of options and far back on the club's outfield depth chart.
Jackson and Thomas were both shuttled back and forth from Indianapolis to Pittsburgh during 2010 and made a combined 23 appearances out of the bullpen for the Pirates. Neither was expected to be an integral part of the team's bullpen next season.
Clement does not have enough Minor League service time to reject his assignment to Triple-A, so he will remain on Indianapolis' roster. Clement will likely be invited to Major League camp next spring, though his participation is questionable since he is recovering from late-season knee surgery.
Gallagher has accrued enough Minor League service time to become a Minor League free agent, but he cannot declare himself one until after 5 p.m. ET on Saturday. The Pirates have until then to try and negotiate a contract with the right-hander, and it's believed that the organization is trying to do so.
In moves that were simply formalities, starter Ross Ohlendorf, right-hander Jose Ascanio and first baseman Steve Pearce were all removed from the 60-day disabled list and put back on the team's 40-man roster.
Also, Chan Ho Park has officially become a free agent. Beginning on Sunday, he will be free to negotiate with any interested team.
After all these moves, Pittsburgh's 40-man roster sits at 38 players. The club has until midnight on Nov. 19 to set that roster in advance of December's Rule 5 Draft.
