Worth noting

• Knuckleballer Eddie Gamboa, who was recently promoted to Triple-A Norfolk, made his first start for the Tides on Wednesday. Gamboa pitched 4 2/3 innings and gave up six runs (five earned). He struck out four batters and walked three.

While at Double-A Bowie, Gamboa narrowly missed a no-hitter and then completed a no-hitter.

•Steve Pearce had an MRA on his left wrist, which has been slower to heal than his right wrist. He was examined by Dr. Brian Schofield in Florida on Wednesday.

•Tsuyoshi Wada, who has pitched well in the Minors recently, was considered as a candidate for promotion Wednesday. He didn't get the call because the organization still considers him a starter, and Showalter prefers to have a right-handed long reliever follow a left-handed starter such as Chen if necessary.

• Top position-player prospect Jonathan Schoop (lower back) will start a rehab assignment on Thursday with the Orioles' Gulf Coast League affiliate. It's expected to last a week or more.

• Chris Dickerson was a late scratch from the lineup Wednesday. He was slated to start at designated hitter, and Nolan Reimold started in his place. The rationale for the late switch was not immediately clear.

• The Orioles have not announced a post-All-Star break starting rotation. Showalter said he'll wait for the dust to settle this week before making an announcement.
