Diamond Pro first introduced Double Play Infield Conditioner back in 2012, at the All Star game in Kansas City. Beautiful Kauffman Stadium is home to the Kansas City Royals and head groundskeeper, Trevor Vance. Since then, Double Play Infield Conditioner, the first and finest blended product on the market, has been a popular choice of groundskeepers across the country. It’s an ideal blend of our Vitrified Red Infield Conditioner and Professional Calcined Clay Conditioner, together in ONE bag. Try a bag, and you too will be hooked! Available in 50lb bags, 40 bags per pallet, from your local friendly Diamond Pro distributor.
