Oscar Valdez, Jermell Charlo and Avtandil Khurtsidze were among those who made strong statements in high-profile fights this past weekend and each has been rewarded in the RING Ratings.

Valdez, our No. 7-rated featherweight last week, overcame a spirited challenge from unrated Miguel Marriaga to win a clear decision and retain his title on Saturday. As a result, Valdez moves up one spot.

Charlo (No. 3 last week) overwhelmed Charles Hatley on Saturday, scoring a sixth-round knockout in defense of his junior middleweight title. Charlo changes places with the less-active Miguel Cotto (No. 2 last week).

And Khurtsidze (No. 8 last week) stopped unrated Tommy Langford in five rounds in a middleweight bout Saturday. He also moves up one position.
