Jack Catterall

"El Gato ("The Cat")". That's what they call Jack Catterall, and is ranked #9 at welterweight — close enough to smell the title, dangerous enough that champions don't say his name too loudly.

He mixes it well — 14 stoppages against 19 decisions. Enough pop to keep opponents honest, enough craft to win the rounds when the knockout doesn't come. Add the southpaw stance, and the puzzle gets harder still.

He arrives on a 3-fight win streak — most recently Shakhram Giyasov, Decision (Unanimous). Streaks like that don't stay unnoticed for long.
