The Boston Red Sox didn't add as many arms as they or their fans hoped at the trade deadline. The gap between the first and second starter in the rotation is still significant, and the bullpen could've used more depth to stay fresh as they push for the postseason.
Luckily, Boston's farm system is recently flush with pitching depth, thanks to careful drafting and trading by current and former chief baseball officers Craig Breslow and Chaim Bloom. Pitching had been an area of need in the Red Sox's farm system, but they now have pitching prospects to spare.
