The Padres signed left-hander Matt Riley, outfielder Bobby Kielty and infielder David Newhan to minor league deals, according to MLB.com's Corey Brock (on Twitter). The players will provide San Diego with organizational depth, but do not receive invitations to Major League Spring Training.
Riley, 31, last pitched in the majors for the 2005 Rangers. The former top prospect last played affiliated baseball in the Dodgers organization in 2008. He has a 3.97 ERA with 10.2 K/9 and 4.2 BB/9 in 199 minor league games (121 starts).
Kielty, who tried to convert himself to a pitcher last year, will return to the outfield this spring. The 34-year-old hasn't appeared in the majors since 2007, but he has a .254/.348/.408 line in 2084 plate apperances with the A's, Twins, Red Sox and Blue Jays.
Newhan, who broke in with the 1999 Padres, hasn't appeared in the majors since 2008. The 37-year-old has big league experience at first, second and third and at all three outfield positions.
