Strikeforce mainstay Anthony Ruiz will return to action against Aaron Rosa on the San Jose, Calif., promotion's next stop at the Save Mart Center in Fresno on May 15.

The promotion confirmed the match-up in a press release on Monday. A match-up between Kim Couture and Meisha Tate was formally announced as well.

Rosa, an import from EliteXC, last appeared on manager Monte Cox's Adrenaline MMA 1 card, where he defeated Strikeforce vet Ron Fields by TKO. Prior to that, Rosa was a regular in EliteXC's "Challenger" series, where he went 1-2 before the promotion closed shop. The losses were the sole blemishes in 13 professional fights.

Ruiz, 31, was last seen at Strikeforce's second Playboy Mansion event, where he lost a unanimous decision to Trevor Prangley. In June, Ruiz lost a bid for the Strikeforce light heavyweight title against Bobby Southworth, losing by decision. The slide reversed a November 2007 win over the The Ultimate Fighter alum by cut.

Ruiz's last victory came a month after the rematch loss, where he defeated Jeremy Freitag by decision at EliteXC: Unfinished Business. He carries an overall professional record of 21-12.
