Mariners pitcher Taijuan Walker was limited to just four innings in a loss to the White Sox in Chicago on Sunday. The right-hander permitted one run on two hits and five walks while striking out three over four innings of a 1-0 defeat.

Over his first two starts covering 10 innings, Walker has permitted only four earned runs. He has not logged more than 94 pitches in a start this season for the Mariners. He will make his next start Saturday at home against Oakland.
