SAN FRANCISCO -- The Giants aren't wondering who will be their front-line performers. The issue is how often they'll be available.
San Francisco's anticipated Opening Day contingent is expected to resemble 2015's season-ending squad. Two or three bench or bullpen roles should be available, but otherwise, manager Bruce Bochy already might be able to name the team that will begin the regular season April 4 at Milwaukee.

A relatively large number of Giants spent parts of 2015 on the disabled list. For this group, regaining and retaining health presents a challenge. The Giants won the World Series in 2010, 2012 and 2014 by using their entire roster. To maintain their pattern of winning it all in even-numbered years, they'll need a fit crew just to stay afloat in what should be a competitive National League West.
As Giants pitchers and catchers prepare to report to camp in Scottsdale, Ariz., on Wednesday, MLB.com continues its breakdown of the club and Spring Training-related issues with a look at the projected starting lineup, bullpen and starting rotation.
