One Caroline finally had to work a bit to get the job done, but in the end the result was the same. It was the fourth straight victory for the undefeated filly, who fought off Swift Temper before posting a one-length decision in Friday's $100,000 Sabin at Gulfstream Park.\nAfter leaving the one-mile chute in the Grade 3 Sabin, One Caroline was in front early as expected but was taken back and angled out near the middle of the track by jockey Edgar Prado.\nOne Caroline reclaimed the lead from Dreaming of Liz after going a quarter-mile, settled into the stretch with a clear advantage while dropping to the rail, then was fully extended to withstand Swift Temper.\nSwift Temper broke slowly from her inside post, recovered to striking position down the backstretch, took a run at One Caroline through the stretch, but was not good enough.\nStormin Mon outlasted the others to finish another 8 3/4 lengths back in third.\nOne Caroline is trained by Rusty Arnold Jr. for owner G. Watts Humphrey. She paid $4 after covering a mile in 1:36.87 over a fast track.\n"I wanted to take her to the outside and keep her away from that other horse to help her relax better down the backstretch," Prado said.\n"We knew there wasn't much speed in the race, so I left it up to Edgar," said Arnold. "This filly has lots of speed, but it's relaxed speed, and I may have had her a little too sharp because this was a one-turn mile. She really should be better around two turns and the Rampart, at a mile and one-eighth, should fit her perfectly."\nThe Grade 2 Rampart will be run at Gulfstream on March 29.
