Ultimate Fighting Championship matchmakers undoubtedly envisioned a striker’s delight when they decided to pit Dustin Jacoby and Khalil Rountree against one another.

The battle-hardened light heavyweights will lock horns in a featured UFC Fight Night 213 attraction on Saturday at the UFC Apex in Las Vegas. Jacoby ventures into his latest assignment on the back of a nine-fight unbeaten streak that has seen him compile an 8-0-1 record. The Factory X representative last appeared at UFC on ABC 3, where he knocked out Da Un Jung in the first round of their July 16 encounter. Rountree, meanwhile, has rattled off two straight victories. “The Ultimate Fighter 23” finalist last competed on March 12, when he cut down Karl Roberson with a body kick and follow-up punches in the second round of their UFC Fight Night 203 confrontation.

As Jacoby and Rountree pore over the remaining details associated with their forthcoming clash at 205 pounds, a look at some of the numbers that have accompanied them to this point:

34: Years of age for Jacoby, who was born on April 4, 1988 in Fort Morgan, Colorado.

11: Jacoby victories by knockout or technical knockout, accounting for 61% of his career total (18). His list of UFC victims: Jung, Darren Stewart and Justin Ledet. Jacoby owns one other victory by submission (6%)—he dismissed Ryan Braun with a triangle choke at a Disorderly Conduct event in 2011—and six more by decision (33%).

37: Seconds needed for Jacoby to bury Billy Horne with punches under the Annihilation Productions banner on Sept. 4, 2011. More than 11 years later, it remains his fastest finish to date.

153: Significant strikes landed by Jacoby in a three-round unanimous decision over John Allan at UFC 268 in November 2021. It established a personal high-water mark for the Marc Montoya protégé.

.703: Cumulative winning percentage between the five men—John Salter, Muhammed Lawal, David Branch, Chris Camozzi and Clifford Starks—who have beaten Jacoby. They boast a combined record of 102-43.

32: Years of age for Rountree, who was born in Los Angeles on Feb. 6, 1990.

7: Rountree wins by knockout or technical knockout, accounting for 70% of his career total (10). His list of UFC victims: Roberson, Modestas Bukauskas, Gokhan Saki, Paul Craig and Daniel Jolly. He holds three other wins by decision (30%).

1.85: Knockdowns landed by Rountree per 15 minutes of UFC competition, placing him fourth on the promotion’s all-time list. Only Houston Alexander (4.39), Luiz Cane (2.32) and James Irvin (1.89) have floored opponents with more regularity.

2: Sub-minute finishes on the Rountree resume. He punched out Blake Troop in 34 seconds at a Resurrection Fighting Alliance show on Dec. 5, 2014 and cut down the aforementioned Jolly with a knee strike in 52 seconds at UFC Fight Night 104 on Feb. 4, 2017.
