With the league's most potent offense coming back whole for the most part, there was only one topic in the minds of fans and players alike during the 2013 edition of Brewers On Deck: pitching.

"I think there are far more unknowns this year than there were last year because of a lack of experience," Ryan Braun noted. "Our starting pitchers last year with (Zach) Greinke, with (Shaun) Marcum, guys that have longer track records, whereas this year there are guys that are pretty inexperienced, but also very talented.

"There's a lot of uncertainty, but certainly a lot of talent. I think everybody in here is excited about the depth we now have in our starting pitching."

Yovani Gallardo and Marco Estrada will be penciled in for two rotation positions going into spring training, but four others will battle for the remaining three starter spots.

Mark Rogers, Wily Peralta and Mike Fiers all found success late in the year as the Brewers stormed back into playoff contention while Chris Narveson missed most of last season with a torn rotator cuff.

"Yo (Gallardo) is going to be a starter. We're counting on Estrada being a starter, so now we got three spots," manager Ron Roenicke said. "You've got Peralta, Narveson, Rogers and Fiers. So you got four guys we know can pitch in the big leagues for three spots. It's nice having those extra guys in case guys aren't pitching well."

Peralta went 2-1 with a 2.48 ERA last year in five starts while Fiers maintained a 3.74 era in 127.2 innings pitched. Rogers went 3-1 in seven starts as an August call-up but will have to prove he can remain healthy and efficient as the innings begin to mount up.

General manager Doug Melvin noted Rogers had the most question marks of the four candidates as he has never thrown over 120 innings at any level in one season.
