Brandon Webb pitched his third straight shutout and stretched his scoreless streak to 42 innings, tossing a two-hitter to lead the Arizona Diamondbacks past the Atlanta Braves 4-0 on Friday night. Webb became the first pitcher since Orel Hershiser in 1988 to go at least 40 innings without giving up a run and just the 21st pitcher in baseball history to reach that level of stinginess. It's not like the Diamondbacks are scoring a lot of runs for Webb (13-8). His previous start was a five-hit, 1-0 win over Washington, and he was clinging to another 1-0 lead when Mark Reynolds gave Arizona some breathing room with a mammoth two-run homer off Lance Cormier in the eighth.
