HOT SPRINGS, Ark. – Oaklawn Park’s road to the Arkansas Derby gets serious on Monday with the running of the Grade 3, $300,000 Southwest. Super Ninety Nine has invaded from Southern California for trainer Bob Baffert to lead the 10-horse field. Will Take Charge, Texas Bling and Always in a Tiz are back for a rematch after being separated by a neck in last month’s $150,000 Smarty Jones at Oaklawn. And then there’s Big Lute, who is making his two-turn debut after winning the first race of his career with a Beyer Speed Figure of 89.
