Kranick allowed four runs on seven hits and a walk while striking out three over three innings in a no-decision versus Arizona on Wednesday.
The 24-year-old has now made three starts this year, and the last two have been uninspiring. Kranick owns a 5.73 ERA and 1.36 WHIP through 11 innings this season, which suggests he'll be little more than a fill-in starter while Chase De Jong (knee) is on the injured list. Kranick lines up for a home start versus Milwaukee next week if he remains in the rotation.
