The 25-year-old won four matches during a difficult first year on the tour.
But, after extending his partnership with Club Doncaster into a second season, the Sprotbrough potter is confident of kicking on.
Keogan, who will compete in the English Open at the Barnsley Metrodome next week, said: “I’m very proud to be part of Club Doncaster, representing my hometown as I compete in tournaments.
“They are more than just a logo on my shirt, though, with support and guidance between events.
“My first year on the tour was a real learning curve, but now I feel settled and am already feeling like I am competing better.”
Gavin Baldwin, chief executive of Club Doncaster, said: “I’ve enjoyed following Chris’ progress over his first year on the tour, and I am sure he will go from strength to strength.
“Our growing partnership with Chris shows our commitment to sport in the area, and everyone at the organisation wishes Chris all the best for the rest of the season - starting with the English Open next time out.”
