DEL MAR, Calif. &ndash; An interrupted preparation has left trainer and co-owner Bill Morey concerned that Bold Chieftain will not be at his best for Sunday&rsquo;s $100,000 California Dreamin&rsquo; Handicap at Del Mar.\r\nIf Bold Chieftain runs a disappointing race, he will be retired, Morey said.\r\n&ldquo;We had a couple of little minor setbacks into this race,&rdquo; he said. &ldquo;He hasn&rsquo;t worked in 10 days. Usually, he&rsquo;d have a different schedule. We&rsquo;re doing the best we can to get him to this race.&rdquo;\r\nBold Chieftain, 7, will be retired by the end of the current Del Mar meeting regardless of Sunday&rsquo;s race, Morey said. Depending on Sunday&rsquo;s result, Bold Chieftain&rsquo;s final career start would be the $250,000 Del Mar Mile on turf on Aug. 28.\r\n&ldquo;If for some reason, he doesn&rsquo;t fire to our approval [Sunday], then he&rsquo;ll be retired,&rdquo; Morey said. &ldquo;If we can get the second race out of him, then he&rsquo;ll be retired. He&rsquo;s been a good boy. We&rsquo;re all so grateful to have had him.&rdquo;\r\nIn the last year, Bold Chieftain has won such notable races as the California Cup Classic and the Sunshine Millions Classic, overcoming trouble in the latter race to post a dramatic win by a neck. Based in Northern California, Bold Chieftain won the Grade 2 San Francisco Mile at Golden Gate Fields on April 24 and was second, as the 3-5 favorite, in the Grade 3 Berkeley Stakes there on May 31.\r\nBold Chieftain may not need to be at his best to win the California Dreamin, which is run over 1 1/16 miles on turf for statebreds. The race drew a field of eight, and the only other 2010 stakes winner in the field, Acclamation, may not start.\r\nAcclamation, who won the Grade 2 Jim Murray and Grade 1 Charles Whittingham handicaps at Hollywood Park in the spring, was also entered in Saturday&rsquo;s Grade 1 Eddie Read Stakes. Trainer Don Warren said on Friday that a decision will not be made on a race for Acclamation until Saturday.\r\nBruce&rsquo;s Dream, a winner of 4 of 5 starts, makes his second start of the year, having won an allowance race over six furlongs on turf at Hollywood Park on June 25. Trainer Mike Puype said Bruce&rsquo;s Dream must settle early to be effective over 1 1-16 miles.\r\n&ldquo;If he relaxes, he&rsquo;ll be very strong,&rdquo; Puype said.
