I don’t quite get this one. Ortiz is a better pitcher than Moss, with a better track record. But he’s righthanded and has a lot more experience (though he’s only a year older, if his listed age is correct) and hence makes a lot more money.
The Braves also gave up a minor league pitcher, Manuel Mateo, who was in rookie ball last year. He was good, but that’s so far from the majors that it doesn’t mean a whole lot.
