4:05pm: The Rays will designate Reid Brignac for assignment, Jon Heyman of CBSSports.com reports (on Twitter). The Rays are in need of 40-man roster space, presumably to make official the signings of Luke Scott, Kelly Johnson and Kyle Farnsworth.
Brignac appeared in 16 games for the Rays last year, playing second base, third base, shortstop and left field. The 27-year-old spent most of the season at Triple-A, where he posted a .231/.323/.353 batting line in 400 plate appearances as a middle infielder. Brignac, who is not yet arbitration eligible, has a .227/.268/.317 batting line in parts of five MLB seasons.
