• Matt Harrison, still recovering from two back surgeries, has ramped up his exercise program, but has not yet been cleared to begin throwing. He is hoping that will happen after being examined by Dr. Drew Dosset on June 10. Harrison is still shooting for an August return.
• Pitcher Roman Mendez has developed another stress fracture in his right elbow and will require surgery. He is expected to miss the rest of the season. Mendez is the Rangers' No. 13 prospect, as ranked by MLB.com. Mendez, who was one of three players acquired from the Red Sox for catcher Jarrod Saltalamacchia in 2010, was 2-0 with a 1.86 ERA in 16 games for Double-A Frisco.
• C.J. Edwards, who is ranked as the No. 17 prospect, has been placed on the disabled list at Class A Hickory. The Rangers want to give him a break, limit his innings and have him available for a full season. He is 5-2 with a 2.25 ERA in 11 starts at Frisco with 66 strikeouts in 56 innings.
• Washington on George Brett taking over as Royals hitting coach: "If he has patience and if he doesn't look at all of them like they're George Brett, he will do well, because nobody knows more about hitting than George Brett. He can sit in the dugout and tell you more about the pitcher than anybody. Maybe, he can open up those minds that are locked down because he knows hitting. There will be some ears open, I know that. I don't know what the issues were before, but George Brett has their respect, totally."
