Friday's 3RD race at Gulfstream Park looms as a battle of the unbeatens, as Gemologist and Currency Swap are set to kick off their sophomore campaigns in this one-mile allowance.

Todd Pletcher's Gemologist, last seen landing the Grade 2 Kentucky Jockey Club on November 26 at Churchill Downs, has been rerouted to this spot in a change of plans. He was originally expected to return in Saturday's Grade 2 Rebel at Oaklawn Park, but a couple of factors prompted the target switch.

"Gemologist will stay in Florida," owner WinStar Farm tweeted Sunday. "No plane for a return trip, so he would have to van back. Plus it's a five horse field instead of 14."

The Terri Pompay-trained Currency Swap has not raced since capturing the Grade 1 Hopeful on Labor Day at Saratoga, beating eventual Grade 3 Swale romper Trinniberg. Pompay told Daily Racing Form on Saturday that she was weighing the Gulfstream allowance, as well as this upcoming Saturday's Private Terms at Laurel, for Currency Swap.

The one-turn mile could redound to the advantage of Currency Swap, who has yet to try two turns. Gemologist, in contrast, raced over 1 1/16 miles in his last two starts, and will be shortening up to one turn for the first time since his maiden win.

Both colts will be ridden by their regular pilots -- Javier Castellano will guide Gemologist from the rail, while Currency Swap will break from post 3 with Rajiv Maragh.

John Velazquez takes over on Pletcher's second stringer, Angel's Tune, who drew on the outside in post 5. Rounding out the field are Brother Pat and Jordan's Image.
