The Red Sox on Wednesday signed two amateur international free agents, Mario Alcantara and Raul Alcantara, according to weei.com, which attributed "multiple Major League sources."

Both were signed out of the Dominican Republic, and they are not related to each other or former Red Sox player Israel Alcantara -- an outfielder and first baseman in 2000 and '01 -- the Web site reported.

Raul Alcantara is considered one of the better pitchers available during the international signing period, which started Thursday. The roughly 6-foot-3 right-hander, who sports a mid- to high-80s fastball, is believed to have signed for about $500,000.

Mario Alcantara, also about 6-foot-3 and a righty, is said to sport a high-80s fastball and curveball and is believed to have signed for about $350,000.

Boston has also signed right-handed pitcher Chez Angeloni to a free-agent contract, according to The Baltimore Sun.

Angeloni, a recent graduate of Johns Hopkins University, was the Most Outstanding Player of the 2008 NCAA Division III College World Series.
