Minor Moves: Olivo, Rays, Murphy

We'll keep track of today's minor moves here..

• Catcher Miguel Olivo has asked for and been granted his release by the Reds, reports Jon Heyman of CBSSports.com (via Twitter). It was previously reported that Olivo was mulling whether to accept a $100k bonus and report to Triple-A, or instead test the market. Olivo could be an option for the Marlins, writes Joe Frisaro of MLB.com.
• The Rays have released minor leaguer righties Nick Barnese and Joe Cruz, reports Marc Topkin of the Tampa Bay Times on Twitter. Barnese, a third-rounder from 2007, threw 56 2/3 innings over 12 starts in Double-A last year and mustered only a 5.72 ERA with 4.8 K/9 and 4.0 BB/9.
• Infielder Donnie Murphy exercised his out clause with the Brewers today and took his release, tweets Tom Haudricourt of the Milwaukee Journal-Sentinel.  The 30-year-old hooked on with Milwaukee in December and hit hit .216/.281/.379 in 129 plate appearances with the Marlins last season.  Murphy is a .205/.270/.373 career hitter in 640 big league plate appearances and a .285/.351/.556 career hitter 738 Triple-A plate appearances.
