The San Francisco Giants have claimed infielder/outfielder Micah Johnson off waivers from the Reds. Johnson was just claimed off waivers by the Reds from the Braves last week and he is on the move again. The speedster has 190 stolen bases over the past six seasons in the minor leagues and figures to serve as organizational depth for the Giants. Catcher Tim Federowicz was designated for assignment to make room for Johnson on he 40-man roster.
