Fantasy baseball drafts are in the books and the season is underway, but you didn't think that meant your work was done, did you?
As an owner, your attention must now shift to monitoring the waiver wire for additions that will boost your squad. Most of the high-impact adds come at the beginning of the year, when some top rookies are still available and some undrafted stalwarts prove their merit as capable contributors.
So who's worth watching during the first week of the season? The following 25 players are available in at least half of Yahoo! leagues (with two exceptions slightly over 50 percent), but their level of usability varies. Some could draw universal ownership soon enough while others could help out in deeper leagues.
Don't let Game of Thrones fool you; summer is coming. Much like for those feared brutal winters, fantasy managers better prepare.
