The Pittsburgh Pirates had a lot of injuries last year to their rotation, but remained contenders due to the strong rotation depth. It looks like they'll have strong depth again this year.
Stolmy Pimentel Looks Like a Favorite For the Opening Day Roster. He will probably open the season in the bullpen, but everyone I've talked to in the organization seems high on him, and still views him as a starting pitcher. He could play a Jeanmar Gomez role this year. The link has a great reaction from Ray Searage after seeing Pimentel for the first time last year.
Brandon Cumpton was a great depth option last year, and should return this year in the same role. I looked at his 2013 season, and how he went from an early season disaster to great MLB depth.
