After a phenomenal performance in his first UFC headliner, Tom Aspinall is now sitting among the very top names in the promotion’s heavyweight division.

Aspinall (12-2 MMA, 5-0 UFC) submitted Russian veteran Alexander Volkov in the headlining bout of this past weekend’s UFC Fight Night 204, and he was rewarded with a move up to No. 6 in the latest edition of the UFC’s official rankings.

Aspinall called for a matchup with No. 3 Tai Tuivasa for his next appearance, though promotion officials have yet to reveal their plans for the English contender.

The latest official heavyweight rankings are listed below. Check out the full updated rankings at UFC.com.
