So far, with Matsuzaka sidelined, manager Terry Francona has used both Tim Wakefield and Alfredo Aceves in starting roles and both have shined. But what's the long-term plan for the Sox?
Wakefield is an aging knuckler, who may not be able to put together an entire summer without fading. In 2009, Wake put together an All-Star first half before succumbing to injury and appearing in just four games after July. Aceves is a 16-2 lifetime pitcher but has started just eight of 73 games dating back to 2008.
Another option the Sox have is to bring up a young arm. Felix Doubront, for example, has big league experience and would fill in nicely. He was, however, dealing with injury in spring training and got a late start this year. He's started five games in Triple-A Pawtucket and has a 1.59 ERA.
The team could also track down a veteran to fill the void. With the mid-season break just a month away, teams may start to look forward to dishing away older loose ends for prospects and the Sox have plenty of chips to deal.
