PHOENIX - Arizona has designated infielder Ryan Roberts for assignment, ending the Diamondbacks portion of the career of a popular player known to fans as "Tat Man" for his multitude of tattoos.
The team activated shortstop John McDonald from the disabled list to take Roberts' spot on the roster.
Teams can claim Roberts on waivers, but in the meantime the Diamondbacks have 10 days to work out a trade.
Roberts was the team's regular third baseman in its surprising run to the NL West title a year ago, batting .249 with 19 home runs and 65 RBIs. But his playing time diminished this season and the team recently called up third baseman Ryan Wheeler from Triple-A Reno.
Roberts is hitting .250 with six home runs and 34 RBIs.
