Strikeforce Challengers 10 Lineup Finalized

Chris Gruetzemacher will face Ryan Diaz in a preliminary matchup at Strikeforce Challengers 10 on Friday at the Dodge Theatre in Phoenix. The promotion will feature a 13-bout lineup at the event, which will air live on Showtime.

Gruetzemacher -- a training partner of World Extreme Cagefighting lightweight champion Benson Henderson at the MMA Lab in Glendale, Ariz. -- has posted four consecutive victories since his 25-second submission loss to Joe Cronin in February 2009. The 24-year-old last appeared at Rage in the Cage 140 in March, when he stopped Nadeem Al-Hassan on first-round punches.

Anchored at Arizona Combat Sports, Diaz has not competed since his knockout loss to Reuben Duran at a King of the Cage show in February. The well-traveled 31-year-old has tested his skills against a number of highly regarded fighters, including world-ranked flyweight Mamoru Yamaguchi, former UFC lightweight title contender Hermes Franca and 2009 Dream featherweight grand prix quarter-finalist Abel Cullum. Diaz has secured 10 of his 13 career victories by submission.

A catchweight bout pitting UFC veteran Joe Riggs against Louis Taylor will headline Strikeforce Challengers 10, along with the professional mixed martial arts debut of Ryan Couture, son of UFC hall of famer Randy Couture. In addition, Miesha Tate, Carina Damm, Maiju Kujala and Hitomi Akano will take part in a one-night, single-elimination women’s tournament at 135 pounds. Matchups for the tournament will be announced at Thursday’s weigh-in.
