Katinka Hosszu (HUN) continued her winning ways after a golden run at the first two rounds of the cup. After victory in the 800m freestyle, she added triumph in the 200m freestyle, then the 200m medley before finally having to settle for a silver in her fourth final on day 1 at the Stockholm round of the FINA/Arena World Cup.
In the 800m freestyle, the 23-year-old former 400m medley world champion pulled away from former 800m world champion Lotte Friis (DEN) in the closing 150m for an 8:24.48 to 8:25.96 victory. The bronze went to the winner's teammate, Zsuzsanna Jakabos, in 8:31.96.
In the 200m freestyle, the same two Hungarians finished top two, Hosszu on 1:55.30, Jakabos on 1:56.31, Hannah Miley (GBR) a close third on 1:56.58, 0.07sec ahead of Australian Jessica Morrison.
A 2:08.13 effort in the 200m medley granted Hosszu her third win of the session, the shared silver going to Sophie Allen (GBR) in 2:09.05, Jakabos making the podium for a third time on the day alongside the first Brit home, Miley locked out in 2:09.94.
Hosszu finally had too settle for silver: at the end of the session, over 200m backstroke, Melissa Ingram (NZL) stole the Hungarian's thunder with a 2:04.84 victory. Hosszu took her fourth win over Jakabos 2:07.44 to 2:08.71, the Hungarians soaking up podium visits with each passing race.
Hosszu has $27,500 in earnings so far this season, almost twice as much as any other swimmer on the tour.
