Manager Pete Mackanin said Thompson will remain in the rotation, Todd Zolecki of MLB.com reports.

Thompson has really struggled since his promotion to the majors. He is 1-3 with a 9.79 ERA in his first four starts. Mackanin believes part of Thompson's problem is that he is trying to make perfect pitches. The other problem is that Thompson has been up in the zone, but he was successful in the minors by keeping the ball down. He'll try to get on track when he faces the Nationals on Monday in his next start.
