Brewers Notes: Lohse, Rotation, Mat Gamel

Today, the Brewers are hosting Brewers On Deck, their annual winter fan festival. Here's the news being made at the event:

• Owner Mark Attanasio says there's always a chance the Brewers could enter the bidding for free agent starter Kyle Lohse, according to MLB.com's Adam McCalvy. "It’s a function of size of contract, length of contract." Attanasio said. "Kyle had a phenomenal two seasons the last two seasons. We just have to see if that fits in our overall scheme." Attanasio refused to specifically say if the team has spoken with Scott Boras, Lohse's agent.
• Manager Ron Roenicke indicated Yovani Gallardo and Marco Estrada are locks for the starting rotation leaving Mike Fiers, Wily Peralta, Mark Rogers, and Chris Narveson vying for the other three spots, tweets Tom Haudricourt of the Milwaukee Journal Sentinel. Roenicke questioned whether Narveson, who underwent rotator cuff surgery last May on his throwing shoulder, will be ready for camp; but, assistant GM Gord Ash said everything is great with the left-hander and he is not behind schedule, reports Haudricourt. 
• Roenicke touted the team’s rotation depth, arguing the five starters at the beginning of the season don’t have to be the same five at the end, writes McCalvy. Roenicke referred to options like recently signed free agent reliever Tom Gorzelanny, who has experience as a starter, and prospects Tyler Thornburg and Hiram Burgos.
• Earlier today, we learned the Brewers are seeking first basemen in light of Corey Hart's knee surgery on Friday, which will force him to miss the first two months of the season. Mat Gamel, Hart's replacement, himself underwent knee surgery last May. Assistant GM Gord Ash said Gamel was examined today and "he is ready to go," Haudricourt tweeted. 
• Melvin did say he is talking to a couple of free agent infielders, reports McCalvy on Twitter. Haudricourt opines it sounds like shortstop Alex Gonzalez is still in play (Twitter link). Gonzalez played 24 games for the Brewers in 2012 before his season was cut short by knee surgery.
• The Brewers will lose the only catchers on their 40-man roster, Jonathan Lucroy and Martin Maldonado, to the World Baseball Classic. Haudricourt stumped Roenicke when he asked the manager about the catching depth chart. "Don't ask me that question because I don't know," said Roenicke. "I want a guy that's going to be with us to be working with these (pitchers), to get them locked in. We're not going to have our two guys there talking to them all the time. So it's going to be difficult. There isn't (an obvious No. 3 catcher)." The Brewers will have five non-roster catchers in camp who have a combined six games of big league experience.
