TRADE: The Braves traded right-handed reliever Joe Boever (1-3, 8 saves, 4.65 ERA) to the Phillies for pitcher Marvin Freeman (0-2, 1, 5.57), and put reliever Charley Kerfeld (3-1, 2, 5.58) on waivers.

The two are new teammates on the Athletics. Ozzie is two minutes older than Jose, one inch shorter, 10 pounds lighter, and about $20 million poorer.
