Tillman went seven innings against the Astros on Tuesday, allowing two runs on five hits and three walks with five strikeouts, but was stuck with his sixth loss of the season. Tillman did not allow a run in his first six innings but faded in the seventh, giving up runs on a base knocks by Chris Carter and Jason Castro. Still, it was a significant step forward for Tillman, who had turned in quality starts in just two of his first eight outings of the year. His last one came back on May 1 against the Rays, whom he'll face Saturday in his second start of the week.
