A’s Notes: Lineup, Young, Cespedes, Nakajima

The Athletics held their A's Fan Fest today with manager Bob Melvin and GM Billy Beane hosting a Q&A session. Here are the highlights:

• Melvin says second base will be an open competition between Scott Sizemore and Jemile Weeks while Grant Green, the A's fourth-best prospect as ranked by MLB.com, will also receive a hard look, reports MLB.com's Jane Lee (Twitter links).
• Melvin plans to continue with the Brandon Moss/Chris Carter platoon at first base, tweets Lee. 
• Susan Slusser of the San Francisco Chronicle tweets the A's will not use any one set lineup because Melvin has multiple options depending on matchups and who's hot. 
• Melvin views Coco Crisp as the starting center fielder with Chris Young moving around all three outfield spots, Lee tweets.
• Young says being reunited with Melvin is "like a breath of fresh air." (A's team Twitter feed).
• Melvin calls Yoenis Cespedes one of most talented players in the league and Beane adds he wouldn't be surprised if the 27-year-old Cuban takes it to another level, Slusser tweets. 
• Beane is confident Hiroyuki Nakajima will make a successful transition to MLB, tweets Casey Pratt of CSNBayArea.com. In fact, Beane joked he will have a tougher transition in dealing with the effervescent Japanese shortstop.
• Beane expects their top prospect, outfielder Michael Choice, to open the season in Triple-A, unless something unforeseen happens, according to Pratt (via Twitter).
• The A's are convinced shortstop Addison Russell, last year's first round draft choice, is mature enough to be invited to Spring Training even though it wasn't part of his contract, writes Slusser on Twitter. Slusser adds this is an indication of how much the 19-year-old has wowed the front office.
