Yovani Gallardo is expected to be the ace of the Milwaukee Brewers' rotation.
After that, the team faces some question marks.
Manager Ron Roenicke expects right-hander Marco Estrada to fill a spot. If Chris Narveson is recovered from shoulder surgery that limited him to just two starts a year ago, he'll be back in the rotation.
Gallardo made 33 starts in 2012, posting a 16-9 record and 3.66 ERA while striking out 204.
Prospects will compete for the final rotation spots.
Mike Fiers has the most big league experience of the group, starting 22 games last season while posting a 9-10 record and a 3.74 ERA.
Former No. 1 draft pick Mark Rogers, who has had injury issues, was 6-6 with a 4.72 ERA in 18 starts with Triple-A Nashville and 3-1 with a 3.92 ERA in seven starts with the Brewers before he was shut down for the season.
