Walker allowed six runs on six hits and three walks with six strikeouts in 4.1 innings in a no-decision versus Washington on Sunday.
The Mets gave Walker a four-run lead before he ever got to the mound, but he allowed a solo home run to Lane Thomas and a two-run shot to Josh Bell in the bottom of the first. The right-hander then allowed three more runs before Jeurys Familia relieved him to finish the fifth inning. Walker owns a 4.15 ERA, 1.19 WHIP and 129:49 K:BB through 138.2 innings this season, but he's gone 0-6 with four no-decisions in his last 10 starts. He's in line for a home start in the Subway Series versus the Yankees next weekend.
