If you’re worried about how the Red Sox will replace Pedro Martinez’ innings, wins, presence, etc., never fear. Boston has acquired free agent P John Halama, 32, for a million bucks and a one-year contract. Halama was 7-6 for the Devil Rays last season, and has a career record of 52-43 with an ERA of 4.52, and John Burkett’s old workout shorts and flip-flops are just waiting for him.
