In parts of three big league seasons, Parrino has posted a .186 average over 229 plate appearances. After spending his first two seasons with San Diego, Parrino hit .118 with two doubles in 34 at-bats for Oakland last season.
Parrino has played five positions at the Major League level -- shortstop, second base, third base, right field and left field. After hitting above .300 in the Pacific Coast League in 2011 and '12, Parrino struggled for Triple-A Sacramento last season, batting .210 with three homers and 36 RBIs.
Holland, meanwhile, is recovering from offseason knee surgery and is hoping to be back by the All-Star break. He sustained the injury after suffering a fall in his home on Jan. 7 and underwent surgery three days later.
With the roster move, Holland would now be available to return to the 40-man no sooner than May 29.
