Yu Darvish allowed two runs while striking out nine over 5 1/3 innings of a no-decision against the Astros on Tuesday. Less attractive were the four walks and four hits allowed by the right-hander in his 5 1/3 innings. Darvish owns a 2.82 ERA and 269 strikeouts in 204 innings this season, but he's also walked 78 batters in that time. His final start of the regular season will come Sunday against the Angels.
