Manny Ramirez, who did not travel with the Oakland A's to Japan, strained a hamstring last week and did not join the team in Sacramento. A's manager Bob Melvin said Saturday night that Ramirez would not play in the three-game Bay Bridge exhibition series against the San Francisco Giants. Meanwhile, left-hander Dallas Braden, who was placed on the 15-day disabled list earlier this week, suffered a setback in his recovery from shoulder surgery when he strained his throwing shoulder last week.
