Considering they’re not on the Red Sox’s 40-man roster, outfielder Rusney Castillo and first baseman/outfielder Allen Craig are already facing uphill battles to achieve relevance in Boston. Moreover, their onerous contracts make even short promotions to the majors unlikely, notes WEEI’s John Tomase (via colleague Rob Bradford). Castillo, for instance, would cost the Red Sox $56,596 per day to keep on their 25-man roster. Thus, a two-week stint with the Sox would cost $800K and push them over the luxury-tax threshold, which they’ve been careful to stay under. Castillo and Craig have upped their stock this spring, writes Bradford, but the team unsurprisingly sent the pair back to Triple-A on Sunday. They’ll combine to make $21.5MM in the minors this season.
How can $800K "push them over the luxury tax threshold"?
I thought we had millions to spare after dumping Buch.
