Pablo Sandoval's size and round middle have ignited the internet and brought out the body critics as baseball begins again. Manager Gabe Kapler said Sunday the San Francisco Giants fully expect their ''Kung Fu Panda'' to be ready and in game shape to contribute by opening day later this month even though he is noticeably heavier than during spring training nearly five months ago in Scottsdale, Arizona. ''Pablo's role on this team is to do what he has done over the course of the last couple days, and what he has done for this city and this community in the past, and that is to bring positive energy, get big hits, drive the baseball, and those are still the things we believe he is capable of doing,'' Kapler said.
