Jon Lester pitched 7 2/3 innings of no-hit ball and settled for his second complete game of the season, helping the sizzling Chicago Cubs beat the San Francisco Giants 2-1 on Friday to move a season-high 40 games over .500. Hunter Pence ended Lester's bid for a second no-hitter with a homer to left on a 1-2 cutter. Brandon Crawford followed with a double, and Lester (15-4) got Eduardo Nunez to line to third and worked around Trevor Brown's one-out double in the eighth.
