""Beautiful morning in Arizona," Pablo Sandoval's Tuesday morning tweet said. "Operation Panda (begins) again today. Time to get better for next season."

Just days after Sandoval returned from the Major League Baseball exhibition tour in Taiwan, the Giants' third baseman reported to Triple Threat Performance in Tempe, Ariz., the private facility that whipped him into shape last winter.

Head trainer Dave Groeschner said Sandoval also hit in a cage at the Giants' facilities in Scottsdale on Tuesday."
