UFC 158: By the numbers

The rivalry between UFC welterweight champion Georges St-Pierre and Nick Diaz comes to a head Saturday in the main event of UFC 158. Here are the numbers you need to know for the title fight:

6.03: Diaz's strikes landed per minute in UFC/Strikeforce fights. Diaz has landed more than 100 significant strikes in four of his last five fights, with the lone time under 100 being a first-round TKO of Paul Daley. The leader in strikes landed per minute in UFC-only fights is heavyweight champion Cain Velasquez at 6.37 per minute.

1.2: St-Pierre's strikes absorbed per minute -- sixth best in UFC history and first among active welterweights. In his last five title defenses, none of St-Pierre's opponents have landed more than 24 percent of their significant strikes.

Georges St-Pierre's significant strike defense in last five fights:

UFC 154 - Carlos Condit: 76 percent

UFC 129 - Jake Shields: 81 percent

UFC 124 - Josh Koscheck: 88 percent

UFC 111 - Dan Hardy: 85 percent

UFC 100 - Thiago Alves: 81 percent

55: Average number of significant strikes landed per fight for "Rush" in 19 UFC fights. St-Pierre's total of 1,048 significant strikes landed is the most in UFC history and 190 more than second-place BJ Penn. Diaz has landed 604 significant strikes in 12 UFC fights, for an average of 50.3 per fight.

78: Percentage of takedowns landed for St-Pierre. In his last fight against Condit, St-Pierre took down "The Natural Born Killer" seven times, tied for third most in a UFC fight for the champion. Diaz hasn't been taken down multiple times in his last 15 fights, spanning back to February 2007 at PRIDE 33 when he was taken down three times by Takanori Gomi.

3:38: The minimum amount of time the fight against Diaz must last for St-Pierre to eclipse UFC Hall of Famer Randy Couture (4 hours, 41 minutes, 50 seconds) for third-longest total fight time in the UFC. St-Pierre has had two UFC fights shorter than 3:38 -- a UFC 69 loss to Matt Serra and a UFC 48 win against Jay Hieron.

2: Diaz is just the second southpaw St-Pierre has faced in 19 UFC fights. At UFC 54 in 2005, "Rush" faced Frank Trigg in his only UFC matchup against a southpaw. Trigg landed one punch in three attempts before succumbing to a rear-naked choke in the first round.

405: The number of days Diaz will have gone without a UFC fight -- a span of over 13 months. Diaz was suspended due to failing a post-fight drug test after UFC 143 and fought just once in 2012. The only other year in his MMA career Diaz fought once was his first year of competition in 2001.

Nick Diaz's longest MMA layoffs in days:

February 2012-March 2013 - 405

August 2001-July 2002 - 314

July 2008-April 2009 - 258

June 2009-January 2010 - 237

5: Consecutive title defenses for St-Pierre without a stoppage -- the same as Anderson Silva and Jon Jones have combined in the UFC. Eleven of Diaz's 34 MMA fights have gone to a decision, including six of his eight career losses.

17: The combined number of UFC or Strikeforce main events both fighters have been involved in over their careers. The champion has been in the main event 10 times in his UFC career, starting with his first title victory over Matt Hughes at UFC 65. Since then, only two of St-Pierre's fights haven't been the main event (UFC 100 against Alves and UFC 74 versus Koscheck). Diaz is no rookie, as his last two UFC bouts have been main events as well as five of his six appearances for Strikeforce.

5: The number of men who can say they've fought St-Pierre and Diaz in MMA competition. Penn lost to both men (St-Pierre twice). Condit defeated Diaz for the interim title before losing to St-Pierre. Karo Parisyan faced Diaz (UFC 46) and St-Pierre (UFC 49) in back-to-back UFC appearances, defeating the Stockton bad boy but losing to the Canadian. Sean Sherk went in the opposite order, losing to St-Pierre at UFC 56 before defeating Diaz at UFC 59. Thomas Denny lost to "Rush" in 2003 and Diaz in 2008, the only fighter to be stopped by both men.
