The Grade 2 Elkhorn Stakes headlines a solid Saturday afternoon card at Keeneland. Here are a few opinions: Elkhorn Stakes – Race 9:   DA BIG HOSS (1)  (7-2 morning line, 5-2 value line) Which Da Big Hoss is going to show up for the Elkhorn?  Will it be the horse that devastated KAIGUN and company in the John B. Connally Turf Cup at Sam Houston? Or, will it be the one that disappointed at short odds at Gulfstream on March 5 and Dec. 26?  With Da Big Hoss, it all comes down to trip. In the John B. Connally, Da Big Hoss enjoyed a dream run under Florent Geroux. He saved ground in the pocket, shot through an inviting opening along the inside on the final turn, and flew home to win by open lengths. Contrast that trip to the ones he received at Gulfstream. First, the W. L. McKnight Handicap in December. In that race, Da Big Hoss raced three- and four-wide around all three turns and just couldn’t overcome that situation against the sharp Charming Kitten. Last time out, in the Mac Diarmida Stakes, Da Big Hoss was again forced to cover more ground than his main competition with another three- to four-wide journey. Despite losing those races, the multiple Grade 3 winner was far from embarrassed. On Saturday, Da Big Hoss draws the rail in a race without much speed. It’s very possible Geroux will replicate the Sam Houston journey, opting for the pace-tracking, ground-saving position in the second flight before being produced with his best in the stretch.   I will play Da Big Hoss to win if he meets my 5-2 odds requirements. Multiple-race bettors might also wish to use the razor-sharp Kaigun while single-race players can utilize ST. ALBANS BOY (8) on the bottom of exotic wagers as he makes his second start of the form cycle. Race 7 – MOON RIVER (11)  (20-1 morning line, 15-1 value line) There are two very logical horses in this turf sprint. WHISKEY BRAVO (5) has won three straight and was claimed out of his last race by high-percentage trainer Brad Cox. He has earned Beyers of 90, 92, and 89 in his last three races and any of those speed figures would likely be good enough to win on Saturday. I just didn’t love his last race at Fair Grounds. Although he broke poorly and rushed up to track the pace, Whiskey Bravo ended up in a fine three-wide trip on the turn. He seemed poised to blow by the leaders in the stretch, but hung on his left lead a long way and was pretty fortunate to get his nose down on the wire. SHADOW ROCK (2) has been running competitively in South Florida for Scooter Dickey and will also take a good amount of money at the betting windows. Although second in his most recent start, Shadow Rock had all the best of it from a pace setup. The pacesetters in the seven-horse field dueled through fractions of 20.92 and 43.52 seconds, and the eventual top three finishers were sixth, fifth, and last after the first two calls. The pace simply fell apart and Shadow Rock was one of the horses that inherited a prime finish position. Add in the fact he hopped to his left lead late in the stretch, perhaps due to fatigue, and I’m willing to try and beat him Saturday. Instead, I’ll take a wild stab with Moon River, a horse running out of conditions and trained by a barn that is 0 for 59 over the past three years at Keeneland. Eligible for an non-winners-of-two-lifetime event, Moon River tries this tougher second-level allowance spot following a decent effort at Gulfstream. Despite quick splits, the pace held up that day and Moon River’s four-wide late bid fell a neck short. A lightly raced 4-year-old, Moon River might not have reached his full potential just yet. A couple of fast recent workouts indicate he’s capable of being closer to the pace this time around. I’ll play Moon River at 15-1 or greater and will use him in exotics with the two aforementioned logical horses. There are a couple of interesting maiden races earlier on the card. In the fifth race, I’ll use a combination of TIZTHESOUND (3), TRY YOUR LUCK (12), and PRIVATE CLIENT (2). Private Client is kin to graded stakes winners Diversy Harbor, Snow Top Mountain,  and Keertana, and shows strong workouts for trainer Tom Proctor. CURRICULA (4) and FORECAST (5) lead the way in the sixth. Curricula showed big speed in his course debut last fall, but tired late. Forecast is a second-time starting maiden and that is a potent angle for trainer Steve Asmussen. I’ll use them with debut performer FASHION SETTER (8), a daughter of high-percentage first-out stallion Street Boss out of a stakes-winning sprinter. Best of luck!
