Big Unit knocks off his old team

SCOTTSDALE, Ariz. (AP) -- Randy Johnson looked like his old self against his old team.

Johnson struck out seven batters in three scoreless innings Tuesday in his first start against the Arizona Diamondbacks since leaving for San Francisco as a free agent.

The Giants overcame a 5-0 deficit to beat the Diamondbacks 7-6.

Johnson gave up two singles and a walk and had his slider in top form. He recorded six of his strikeouts with the pitch he usually doesn't break out until later in the spring.

Conor Jackson and non-roster invitee Ryan Roberts collected one hit apiece off Johnson.

D-backs left-hander Doug Davis retired all six batters he faced despite being uncertain if he would start because of a nerve condition in his left arm.

Miguel Montero added two hits, and Justin Upton had a RBI triple for Arizona.

Today in Tucson, Diamondbacks right-hander Brandon Webb is scheduled to make his first start of the spring against Team Mexico. Webb has been held out since feeling tightness in his right forearm while playing catch Feb. 26, the day before his first scheduled spring start against the White Sox.
