Third baseman Rio Ruiz from Bishop Amat High in La Puente, Calif. recently had a blood clot broken up in a vein near his clavicle by his right shoulder. The news was first reported by Eric Sondheimer of the Los Angeles Times.

According to Sondheimer:
 

Ruiz began complaining about a dead arm two weeks ago. He had swelling in a biceps muscle in his shoulder, [Bishop Amat head coach Andy] Nieto said. A blood clot was discovered and the procedure took place on Friday.

Ruiz also hyperextended his left knee playing football last fall.

The Southern California commit ranked No. 34 on Baseball America's preseason ranking of the Top 100 prospects for the 2012 draft. He is a physical third baseman with big hands and present strength. He has a knack for making good contact and figures to develop good power with his frame. He also has profile arm strength for third base, sitting 90-93 mph when he gets on the mound.
