The Red Sox have increased their security after receiving a number of threats heading into their three-game series with the Rays in Tampa, according to The Boston Herald. The Sox recently received a mailed threat, which targeted black and Latin players, according to sources. Boston will play in Tampa on Monday, Tuesday, and Wednesday night. The threat is believed to be unrelated to the recent tensions between the Sox and Rays, who play for the first time since their brawl at Fenway Park earlier this month.
