CHICAGO — Alexi Ogando lasted only 2 1/3 innings and was rocked for five runs, including three on back-to-back homers in the third inning, as the Cubs rolled to a 6-2 victory over the Rangers.Ian Kinsler started the fourth inning with his fifth homer of the season, and Nelson Cruz had another solo shot in the seventh. Just about the only other good news for the Rangers is that they have to make up only one game at a later date rather than two.The makeup date for the Wednesday cancelation remains to be determined.Ogando (2-1) was lucky to escape the first inning without any damage, as Mitch Moreland snared an Anthony Rizzo liner that was headed to the corner for an RBI double. Ogando also was fortunate in the second, when he allowed the game's first run.But the Cubs opened the third with four straight base runners, all of whom scored. David DeJesus opened the inning with a triple and quickly came home on a wild pitch. Starlin Castro then walked and scored ahead of a two-run shot by Rizzo.Alfonso Soriano followed with a shot into the left-field bleachers. Ogando retired Nate Schierholtz before getting the hook having thrown 71 pitches on a day he continued to struggle with his fastball command.Derek Lowe replaced Ogando and allowed one run in 2 2/3 innings, by far his longest outing of the season and the first for the Rangers' long reliever since April 9.
