Carlos Santana has begun baseball activities and has not shown symptoms of the concussion that sent him to a special seven-day disabled list last Saturday. "He swung the bat in the cages today," Indians manager Manny Acta said Friday. "Tomorrow he's going to catch guys in the bullpen, run the bases and take regular BP. After that, he'll be tested. If everything is OK, he'll try to get approval from MLB." Under the various protocols dealing with concussions, a player must be certified by a doctor as fit to play then Major League Baseball makes a final ruling.
