Burst onto the scene in August 2012 when he won three Challenge Tour titles in four weeks to earn instant promotion to The European Tour. Finished second to Charl Schwartzel in the 2013 Alfred Dunhill Championship, albeit by a distant 12 shots, before continuing to show his potential with an impressive 2014 campaign. After a slow start to the season, the Swede showed some very good form at both the Irish Open and Aberdeen Asset Management Scottish Open, where he finished tied third and second respectively. Those performances helped Kristoffer finish in the top fifty on The Race to Dubai, in 47th place – his best season on The European Tour by a long way. His first win on the Challenge Tour, in the Finnish Challenge, came in only his second Challenge Tour appearance, having finished tied ninth on his debut in Brittany in May. Then added the Norwegian Challenge the following week and the Rolex Trophy a fortnight after that, sandwiching a tied third place finish in Denmark in between. Returned to Challenge Tour action in October and won the Crowne Plaza Copenhagen Challenge hosted by Royal Golf Club to move to the top of the Rankings. Took second place in the final Rankings after a tied seventh place finish at the Grand Final. His close friend and compatriot Alex Noren claims Broberg practises more than any other player in the world, regularly clocking up 12 hours a day when he is at home during the Swedish summer.
