Max Baer?
Yes
D’oh! :smack: Ken Norton.
Baer was #22. I’ll narrow it down a little - he’s on the nickname list.
No, he won two fights against Andrew Golota by disqualification, but neither was a title fight.
Yes
Holyfield then? Ear-gate with Tyson
Holyfield was #77.
ETA: Oh, you meant the win by DQ question.
No, Holyfield was the champion; that was a (successful) title defense.
Pravnik’s list:
Jeff Lacy - Left hook
Manny Pacquiao - Does Pacman count as a nickname?
Floyd Mayweather, Jr. - “Money” (has another) Used to be pretty boy
Ronald Wright - Winky
Vitali Klitschko
Wladimir Klitschko - One of these two is Dr Steel hammer. Or Steel something. The other also has a lame Dr nickname that escapes me.
siz2: Name the first player to wear the #9 shirt in the English FA cup final.
Willfully obscure one for the boxing fans:
Name the only heavyweight boxing champion in history who spoke Welsh 
Wladimir is Dr. Steelhammer, Vitali has a “Dr.” followed by a name shared with a superhero. Pac-Man does indeed count. That leaves just Chacon and Jenkins, and those might be too obscure. Really, almost the only thing I know about Jenkins is his awesome nickname.

Jack Dempsey?
RJ - 9 - Busy Ssissors is right. Montreal, in 1976, held its sailing competition in Kingston, Ontario, which is on Lake Ontario. Montreal itself is on the St. Lawrence River.
RJ - 10 - Really Not gets this one. Moses won 107 straight hurdling competitions.
RJ - 11 - Nobody has this one yet. Dallas and the NY Islanders are wrong; one expansion team won the Cup before the Islanders did.
RJ - 12 - Elvis is correct: Seattle is the northernmost city with an NFL team, at approximately 47 degrees latitude (and would remain so even if the Bills move to Toronto.) Minneapolis is second, followed by Green Bay.
EL2: What is the southernmost city to have hosted a Grey Cup champion?
Baltimore.
EL3: In what Olympic event was future General George Patton a competitor?
I’m taking a wild guess here, but wasn’t it pentatholon? It’d certainly fit his character.
EL5: Who was the MVP of both World Baseball Classic tournaments?
Daisuke Matszuzaka.
Dempsey was #7.
Tommy Farr was Welsh, but he was never world heavyweight champion…
RJ- 11 is easy to any Bruins fan- Flyers in '72… *^$#%!! Bernie Parent !!!
I apologize if this was answered, but I believe Lennox Lewis won a title by DQ
No, his only win by DQ was a successful title defense.
Specifically, the 400 meter high hurdles.
Mike Tyson? I remember him having a devastating punch.
