The Rays have signed Juan Miranda, Matt Mangini, Jhonny Nunez, and Ricky Orta to minor league contracts, tweets Marc Topkin of the St. Petersburg Times.
Of the four signings, the 28-year-old Miranda is the most intriguing. He spent a good chunk of 2011 in the bigs with the Diamondbacks, posting a .717 OPS in 202 plate appearances.
