Newly-acquired Cardinals pitcher Justin Masterson (5-6) was not at his best in his St. Louis debut, but did enough for the win Saturday night against the Brewers. The right-hander yielded five runs on seven hits and three walks while striking out four over six innings of a 9-7 victory.

Masterson has allowed five earned runs in three of his last four starts. He owns a 5.63 ERA and a 1.65 WHIP over 20 starts (104 innings). His next start will come Friday at Baltimore.
