Sox look to tweak East title team for ’17 run

For Red Sox president of baseball operations Dave Dombrowski, there are two major areas of focus in his quest to put together a team that can defend the American League East title and make a deep run next October. The first is to try to replace David Ortiz’s elite production. The second is to rebuild a bullpen that could lose free agents Koji Uehara, Brad Ziegler and Junichi Tazawa.
