Coach Michael Bohl has re-signed with swimmer Park Tae-hwan and will coach him through the 2012 London Olympics.

The sports division of SK Telecom, which sponsors Park, says the Australian coach renewed the contract for two more years.

SK did not disclose the financial terms but said Bohl received about a 50-percent raise.

Park says he's happy to continue training with Bohl and vowed to “stand on top of the world again” at the world championships in July.
