Thirty Innings, No Runs

The Pirates have not allowed any runs in their past 30 innings pitched, a streak spanning four games, three of them shutouts. Yes, it's been against the Phillies and White Sox, who aren't a modern-day Murderers' Row. But this is tied for the fifth longest scoreless streak in Pirates history:

1. 45 innings: July 29, 1931, fourth inning - August 8, 1931, fifth inning
2. 36 innings: May 17, 1972, first inning - May 21, 1972, ninth inning
3. 35 innings: May 28, 1971, seventh inning - June 2, 1971, fifth inning
4. 33 innings: August 1, 1958, first inning - August 3, 1958, second game, sixth inning
5. 30 innings: September 29, 1976, seventh inning - October 3, 1976, ninth inning
6. 30 innings: June 13, 2015, ninth inning - June 16, 2015 ninth inning (and counting)
7. 29 innings: September 12, 1933, first inning - September 15, 1933, second inning

Jeff Locke will try to keep it going against the White Sox at U.S. Cellular Field tonight. He's an unlikely candidate to keep a scoreless streak alive, with a 4.90 ERA and at least one run allowed in ten of his twelve starts this year. But he's allowed no runs in two of last four starts (5.2 innings pitched in a 5-1 win against Miami on May 26, 6.0 innings pitched in a 1-0 win over Philadelphia on June 12), and the White Sox have scored the second-fewest runs per game (3.5) in the American League so far this year, so who knows?
