McDonald brings fresher clay experience, advancing past Jenson Brooksby in Houston's R1 last month before a R2 loss to Thiago Agustin Tirante and a R32 defeat to Chun-Hsin Tseng at Oeiras Challenger last week. Harris, rebounding from injuries with a Tenerife Challenger title on hard courts in February, must adapt to the altitude-enhanced bounce on Manolo Santana courts. No reported injuries; best-of-three sets favor the trader consensus on recent form and rankings.",
