Alfonso Soriano got the word Sunday that the Cubs will activate him from the disabled list for Tuesday's series opener against Milwaukee. But that didn't seem to raise the frustrated left fielder's spirits much. Hoping to get the go-ahead to play during the weekend series at Arizona, Soriano initially seemed more disappointed that his return was delayed until the next series than excited to be cleared a week earlier than anticipated when he tore his right quadriceps Aug. 5. ''I'm frustrated because I want to play and I can play,'' said Soriano, who huddled with trainer Mark O'Neal for a lengthy explanation of the team's decision and specifics of the healing process. He then met with manager Lou Piniella and told Piniella he could play Sunday.
