The 25-year-old Brit’s sixth-round victory improved his perfect record to 25 wins, 17 by the way of knockout – and was the most impressive display of his professional career.
Jackiewicz, a former world title challenger, had never been stopped during his 49 professional career fights but was made to look extremely ordinary by his classy opponent.
The man from Sheffield dominated from the outset, dictating the tempo of the fight with his jab and backing his opponent off with his right hand whenever he got too close.
Jackiewicz looked flat-footed and short of ideas as he attempted to stalk the more athletic Brook around the ring, barely throwing a punch.
By the fifth round Brook was in complete control, rocking his durable opponent with quick flurries which he was unable to respond to.
The sixth round was much the same as Jackiewicz was only able to display how well he could take a punch, the one sided nature of the exchange forcing the referee to stop the fight with less than minute in the round to go.
The Pole was not in trouble at the time but was incapable of responding to Brookâ€™s quick and damaging flurries, the referee saving him from an even greater beating in a fight he was losing.
“Basically, he didn’t even hit me tonight and I wasn’t out of second gear,” said Brook after the fight. “I could have taken him out at any time and was just enjoying myself.”
Asked about the possibility of a super fight against world champion Amir Khan, Brook added: “Yeah I want it, I want it. He doesn’t want me.
“We know that we’ve got his number. It’s a matter of time, I keep beating what Eddie [Hearn] puts in front of me and it’s got to happen, the public want it. They’re going to demand it and I think it’s going to happen next year.”
