Cardinals pitcher Adam Wainwright, who gave up four runs in his previous starts, tossed a quality start but suffered his fifth loss of the season Sunday night against the Rangers.

Wainwright (10-5) was unable to hang on to a slim, one-run lead as he surrendered a run-scoring singles to Leonys Martin and Ian Kinsler in the seventh inning. He yielded two runs -- one earned -- on six hits and one walk while striking out six in 6 2/3 innings.

Wainwright has allowed two runs or fewer in four of his last five starts. He has a 2.31 ERA and a 1.01 WHIP through his first 16 starts. He is scheduled to make his next start Saturday at Oakland. He is 7-1 with a 2.71 ERA in nine starts away from home.
