A busy weekend for junior middleweights gave the 154-pound Top 10 a new look.

Erislandy Lara (No. 1 last week) retained his position after a unanimous-decision victory over Vanes Martirosyan (No. 7 last week) on Saturday in Las Vegas, which pushed Martirosyan down to No. 9.

Austin Trout (No. 2 last week) lost a unanimous decision to Jermall Charlo (No. 5 last week) on the Lara-Martirosyan card. As a result, they swapped places.

And Jermell Charlo (No. 4 last week) held his position after stopping John Jackson (unrated last week) in the eighth round of a fight Charlo was losing.

The new Top 10:

1. Erislandy Lara
2. Jermall Charlo
3. Miguel Cotto
4. Jermell Charlo
5. Austin Trout
6. Demtrius Andrade
7. Julian Williams
8. Liam Smith
9. Vanes Martirosyan
10. Carlos Molina

In other divisions:

HEAVYWEIGHT

Joseph Parker (No. 9 last week) passed the biggest test of his career on Saturday in New Zealand, defeating Carlos Takam (unrated last week) by a unanimous decision. As a result, he swaps places with Bryant Jennings (No. 8 last week). Jennings has lost his last two fights.

David Haye (No. 10 last week) stayed put after he stopped Arnold Gjergjaj on Saturday in London.

CRUISERWEIGHT

Three 200-pounders were in action this weekend.

Denis Lebedev (No. 2 last week) retained his position after his brutal second-round knockout of Victor Ramirez (No. 10 last week) on Saturday in Moscow. Also, on Friday in Paris, unbeaten puncher Yunier Dorticos (unrated last week) stopped Youri Kalenga (No. 7 last week) in the 10^th round.

As a result, Ramirez and Kalenga drop out of the Top 10. That made room for Tony Bellew and Dorticos to enter at Nos. 9 and 10, respectively.

FLYWEIGHT

Nawaphon Por Chokchai (No. 9 last week) held is position after stopping Macrea Gandionco (unrated last week) in three rounds in Thailand.
