BALTIMORE -- The Sons of Gary DiSarcina continue to make a steady exodus from Pawtucket, though for each so far, it has been a round-trip ticket.
On Sunday, reliever Pedro Beato became the fifth PawSox player to be activated by the big club since Tuesday, when Jose De La Torre started the conga line of callups that also has included Alfredo Aceves (Wednesday), Alex Wilson (Thursday) and Rubby De La Rosa (Friday).
De La Rosa came and went without appearing in a game, but there is purpose behind his demotion. With Clay Buchholz still a question mark regarding his next start and a candidate for the disabled list, the Sox want De La Rosa to start Monday for the PawSox in Columbus. That would put him on regular rest for Saturday, when he would be a candidate to start in Detroit in the event Buchholz can't go.
Sox manager John Farrell said Allen Webster also has put himself in the conversation as a potential Buchholz replacement by virtue of his six-inning, one-hit performance Friday night.
Farrell made it official that Aceves, who has allowed one run in each of two emergency starts after a callup, will start one of the games in Tuesday’s doubleheader against the Rays at Fenway. Felix Doubront will start the other, order to be determined.
Beato, meanwhile, made seven appearances last July for the Mets after opening the season on the DL with shoulder stiffness. He made 60 appearances for the Mets in 2011, beginning his career with a string of 18 2/3 innings without allowing an earned run. Beato came to the Sox last Aug. 16 in a deal for catcher Kelly Shoppach and is 4-1 with a 1.89 ERA for the PawSox. He has a save or win in four of his last five outings.
