Jameson may make multiple starts as a fill-in for Zach Davies, whose oblique strain is expected to take "several weeks" to heal, Nick Piecoro of The Arizona Republic reports.

EDGE Analysis

Arizona manager Torey Lovullo described Davies' injury as "more than a (Grade) 1," with a Grade 1 strain being the least severe. Jameson excelled in his first start as a replacement for Davies, shutting down the Brewers over four scoreless innings last Wednesday. His next expected start is Tuesday in St. Louis. Jameson pitched as a starter in spring training -- he eventually lost out on the No. 5 job to Ryne Nelson -- and should be able to build up higher pitch counts and get deeper into games.
