Dave Zabriskie (Garmin-Barracuda) was the big loser of yesterday’s 187.2 km run to Pandan Indah, conceding more than 19 minutes to stage winner Jose Serpa (Androni Giocattoli), his yellow jersey, and any hope of overall honours.
The American dropped off the back of the bunch at the same point as an injured Adam Phelan (Drapac), with the Australian barely able to use his right knee since a crash on Saturday.
Initially several teammates were sent back to help Zabriskie, but when it became clear that he was not going to be able to recover, only Raymond Kreder remained to escort him to the finish.
Competition Director Allan Peiper said the team was still trying to figure out exactly what had gone wrong with the American.
"We are really not sure what happened to Dave Zabriskie," said Peiper to Cyclingnews. "He had a little fever two nights ago but before yesterday’s stage he seemed okay health-wise. The only other explanation could be some heat stroke or severe dehydration from the really hot days just before. We’re still unsure though. "
The team is now hoping that Tom Danielson, who has won the race once before back in 2003, will be able to retake yellow after yesterday's disappointment.
"We will see what happens on Genting, but we’re banking on him," concluded Peiper.
