Wrist tendinitis sidelines Johnson

WASHINGTON -- Struggling Braves second baseman Kelly Johnson has been placed on the 15-day disabled list with right wrist tendinitis.

The move was made before Atlanta opened a three-game weekend series against the Washington Nationals on Friday.

Braves manager Bobby Cox said Johnson's recent slump could be traced to the wrist problem. He's on a 9-for-74 skid that has dropped his batting average to .214.

To take Johnson's place on the roster, the Braves purchased the contract of infielder Brooks Conrad from Triple-A Gwinnett. Conrad was hitting .259 with nine home runs and 38 RBIs. His 46 runs scored ranked fifth in the International League.
