Ober won't make his second start of the week Sunday against the Yankees as initially anticipated, with Griffin Jax instead receiving the nod for that game, Betsy Helfand of the St. Paul Pioneer Press reports.

EDGE Analysis

In an effort to limit the workloads of Ober and fellow rookies Jax and Charlie Barnes, the Twins opted to expand their rotation to six men for at least this week. Rather than having Ober -- who tossed a quality start in Tuesday's loss to Cleveland -- make his second start of the week Sunday, manager Rocco Baldelli's decision to add a bullpen day to the mix for Thursday's series opener in New York pushes the 26-year-old right-hander's next turn back to next week. Ober is now expected to make his 15th start of the season Aug. 24 in Boston.
