2014 Outlook: Tazawa's strikeout and walk rates are elite, but his fly-ball tendencies keep him from being a truly elite reliever, since home runs will always be a concern. That said, fly-ball pitchers should carry low hit rates, but in 2013 Tazawa was snakebitten in that regard. It's hard to say where Tazawa is in the pecking order behind closer Koji Uehara, but his skills are as closer-worthy as anyone's in the Boston bullpen. If you're willing to incur the home run risk, Tazawa is a viable option to protect ratios in mixed leagues as well as deep formats, even without accruing saves.
2014 Outlook: Ticketed as Jacoby Ellsbury's successor in center field for the Boston Red Sox, Bradley should not elicit hopes from his fantasy owners of Ellsbury-like fantasy production. "Ellsbury lite" might be the fairest comparison. Bradley isn't quite Ellsbury in terms of batting average or home run production, and he's not nearly as fast, with 10/25 numbers his likely ceiling, at least initially. Bradley does provide more potential in terms of defense and on-base ability, however, and in leagues that weigh on-base percentage and/or walks, he's especially intriguing. As things stand, he should receive enough playing time to crack the mixed league radar, but he's of most worth as a mid-to-late pick in AL-only formats.
2014 Outlook: The Boston Red Sox have a bevy of platoon candidates on their roster, and Carp is one of the simplest to project: He is a left-handed hitter who mashes right-handers and has a hint of pop, and therefore can steal starts against righties at first base or in left field. He was a .300/.367/.537 hitter on his favorable side in 2013, and as a 27-year-old, he's in good shape for a repeat of last season's numbers. Consider Carp an AL-only late-rounder and an even more attractive plug-in in leagues that allow daily transactions.
2014 Outlook: Nava is a handy matchups play in both the real game and fantasy. Although a switch hitter, he is a lifetime .292/.390/.443 hitter against right-handers (as a lefty hitter) and .223/.307/.328 against lefties, and the Boston Red Sox have other righties they can pair with him at first base or at the corner outfield spots. Nava will get his time against right-handers, enough to help an AL-only team at the back of the roster, but he's unlikely to take any more significant career steps at the age of 31.
2014 Outlook: While the axiom about never having too much pitching usually rings true, Boston bringing in Chris Capuano after Ryan Dempster opted to take the year off is a signal that Doubront will not be handed the fifth rotation spot for the world champs. Doubront's 2014 featured a splendid 15-game stint in which he compiled a 2.55 ERA and 1.21 WHIP, so he has the talent, he just needs to be more consistent with respect to throwing strikes. Given that parsing data can be misleading, those 15 tilts should at least put Doubront on your radar in mixed leagues, especially if you can use him mostly at home. This is one of those rare occasions a pitcher may be more mixed-worthy than deep-league worthy, because you'd be more apt to stream him. His walks and penchant for the long ball make him risky in AL-only setups, especially if his punchouts don't rebound.
2014 Outlook: Lost in the hoopla of Boston's magical season was that Ross struggled mightily at the dish, fanning at a career-worst rate while hitting far fewer line drives than normal. Now 37 years old, not much of a bounce back should be expected.
