A compelling cruiserweight division became even more interesting last weekend.

Unbeaten Russian Murat Gassiev (No. 10 last week) staked his claim as a major player at 200 pounds by earning a split-decision victory over countryman Denis Lebedev (No. 1 last week) on Saturday in Moscow.

Two judges had Gassiev winning comfortably (116-112 and 116-111) while the third scored it narrowly for Lebedev (114-113).

As a result, Gassiev (24-0, 17 knockouts) moves up to No. 2, behind only Ukrainian sensation and new No. 1 Oleksandr Usyk. The cruiserweight championship is vacant.

Lebedev (29-3, 22 KOs) drops to No. 4. He hadn’t lost since he was stopped by Guillermo Jones in 2013.

This is the new 200-pound Top 10:

C. Vacant
1. Oleksandr Usyk
2. Murat Gassiev
3. Tony Bellew
4. Denis Lebedev
5. Krzysztof Glowacki
6. Marco Huck
7. Mairis Briedis
8. Firat Arslan
9. Ilunga Makabu
10. Yunier Dorticos

In other divisions:

HEAVYWEIGHT

Kubrat Pulev (No. 3 last week) retained his position after stopping Sam Peter (unrated last week) in three rounds Saturday in Sofia, Bulgaria.

MIDDLEWEIGHT

Billy Joe Saunders (No. 3 last week) received a stiffer-than-expected challenger from unrated Artur Akavov but emerged with a unanimous-decision victory Saturday in Paisley, Scotland. Thus, he remains at No. 3.

JUNIOR WELTERWEIGHT

Julius Indongo (unrated last week) stunned Eduard Troyanovsky (No. 4 last week), stopping the previously unbeaten Russian only 40 seconds into their fight Saturday in Moscow. Indongo, from Namibia, enters the Top 10 at No. 8. Troyanovksy drops to No. 10. Jose Ramirez (No. 10 last week) is pushed out.

We also used this opportunity to shuffle the 140-pound ratings slightly. Here’s the new Top 10:

C. Terence Crawford
1. Viktor Postol
2. Adrien Broner
3. Antonio Orozco
4. Adrian Granados
5. Ricky Burns
6. John Molina
7. Regis Prograis
8. Julius Indongo
9. Jack Catterall
10. Eduard Troyanovsky

LIGHTWEIGHT

Denis Shafikov (No. 7 last week) defeated Richard Commey (No. 5 last week) by a split decision in Moscow, Commey’s second consecutive split-decision setback against a top-level opponent on the road. He lost to Robert Easter in September.

Shafikov and Commey switch places in the ratings, the former moving up to No. 5 and latter dropping to No. 7.

JUNIOR LIGHTWEIGHT

Tevin Farmer enters the ratings at No. 10 after easily outpointing Dardan Zenunaj (unrated last week) on Friday in Philadelphia. Saul Rodriguez (No. 10 last week) drops out.

FLYWEIGHT

Juan Carlos Reveco (No. 6 last week) outpointed Diego Liriano (unrated last week) on Friday in Mendoza, Argentina, to retain his position.

JR. FLYWEIGHT

Randy Petalcorin (No. 2) retained his position after outpointing grossly overmatched countryman Arnold Garde.
