In his last five starts, Wang has allowed three earned runs or fewer, posting a 2.50 ERA during that stretch.
The right-hander has also induced at least one double play in each of his starts this season, mostly by using his sinkerball. According to the Elias Sports Bureau, Wang's streak is the longest by a Yankees pitcher from the beginning of a season since Tommy John in 1979 (17 starts).
Wang hasn't given up a homer since Seattle's Ben Broussard hit a shot to right field to break up Wang's bid for a perfect game with one out in the eighth inning on May 5. Wang owns a streak of 43 consecutive innings without giving up a home run.
Arizona will counter with last year's Cy Young Award winner, Brandon Webb, who is 6-3 with a 3.13 ERA this season.
NYY: RHP Chien-Ming Wang (5-4, 3.73 ERA)
Wang had an "exploding" sinker in his last start on Sunday, according to Yankees manager Joe Torre. The right-hander beat the White Sox in the third complete game of his career. Wang gave up five hits and struck out four in the 104-pitch effort.
ARI: RHP Brandon Webb (6-3, 3.13 ERA)
Webb pitched magnificently for his second straight start to beat the Giants, 1-0, at Chase Field in his most recent outing. Webb gave up six hits over seven scoreless innings, recording his third straight win.
