Diamondbacks pitcher Chase Anderson continued to struggle on Wednesday, dropping his fourth straight decision in his team's 5-1 defeat to the Pirates. The right-hander permitted three runs on eight hits and three walks while striking out five over 3 2/3 innings of work.

Anderson started the season 5-0, but over his last four starts covering 19 2/3 innings, he has allowed 11 earned runs. He owns a 3.91 ERA and a 1.39 WHIP over nine starts (48 1/3 innings). He will look to snap his skid on Monday at home against Miami.
