Coello and Tapia headline a loaded Valladolid P2 men's semifinal Saturday

Top seeds Arturo Coello and Agustin Tapia open the Valladolid P2 men's semifinals at 6pm Saturday, with Ale Galan and Fede Chingotto due on the same Caja Rural Zamora center court 90 minutes later. Both favorites cruised through Friday's quarterfinals, and the home crowd in Valladolid is bracing for another all-Spanish final on Sunday.

The top half: Coello and Tapia chase the final

Coello and Tapia, the world No. 1 pair and the closest thing this draw has to local heroes, brushed aside Jairo Bautista and Inigo Jofre 6-1, 6-4 in the last eight. They face Juan Lebron and Leo Augsburger, who reached the semis without hitting a ball Friday when their quarterfinal opponents withdrew injured. Lebron, a former world No. 1, gives that pairing a dangerous edge if the top seeds drop their level.

The bottom half: Galan, Chingotto and a giant-killer

Galan and Chingotto were just as ruthless, beating Paquito Navarro and Martin Di Nenno 6-1, 6-4. Waiting for them are Fran Guerrero and Javi Leal, the surprise package of the week. The unseeded pair knocked out fourth seeds Franco Stupaczuk and Mike Yanguas 7-6, 6-4, taking the opening tiebreak to love, so Galan and Chingotto cannot afford to look ahead to Sunday.

What to watch

A Coello-Tapia vs Galan-Chingotto final is the storyline everyone expects, and it would be a rematch of their recent Rome showdown. But this draw has already produced one upset, and the late evening start means the cooler, faster night conditions could level the gap between the seeds and the outsiders.
