SALT LAKE CITY Jimmy Swift's walk-off sacrifice fly scored Roberto Lopez to lift the Salt Lake Bees to a 2-1 victory over the Colorado Springs Sky Sox Thursday at Spring Mobile Ballpark.

Lopez doubled off Nick Schmidt (1-2) to lead off the ninth and went to third on a sacrifice bunt by Luke Carlin. Swift's fly to right dropped the Sky Sox to 14-10.

Colorado Springs starter Aaron Cook had his best outing since returning to the Rockies organization, allowing one run over six innings and escaping a bases-loaded jam in the sixth by striking out Lopez.

Matt McBride's second-inning solo home run was the only offense Colorado Springs could manage.
