Familiarity eventually worked in Gutierrez's benefit. From 2009-11, he appeared in 143 games for the D-backs -- finishing 59 of them while posting a 4.62 ERA -- and Angels general manager Jerry Dipoto worked in that front office.
Dipoto likes Gutierrez's stuff -- a fastball that consistently sits in the mid-90s with a curveball and slider he considers above-average -- and was intrigued by his bounce-back 2013 season for a crowded Royals bullpen, where Gutierrez posted a 3.38 ERA in 29 1/3 innings.
On Thursday, the Angels guaranteed him a spot in their upstart bullpen, designating right-hander Billy Buckner for assignment in order to create room on the active roster. Gutierrez doesn't have a concrete role yet, but he's capable of pitching two innings at a time.
"I'm really happy to be here," said Gutierrez, who had Tommy John surgery late in 2011 and struggled mightily in the Minors in '12. "Jerry knows me from the Diamondbacks, and he told me he's happy to have me on this team."
