Tim Hudson tossed five shutout innings, then stuck around in the dugout long enough to watch old pal Barry Zito pitch a perfect inning of relief for the Oakland Athletics during the San Francisco Giants' 2-1 victory Saturday in the final spring tuneup for both teams. As Hudson got his work in for the reigning World Series champion Giants, Zito warmed up in his original ballpark and familiar No. 75 green jersey. Zito also spent seven years with the Giants on a $126 million deal before sitting out last season.
