In his sixth rehabilitation start for Triple-A Norfolk, left-hander Tsuyoshi Wada allowed eight runs (seven earned) on six hits and two walks at Indianapolis. Wada struck out two batters and allowed a grand slam to Brett Carroll in the first inning. He's allowed at least three runs in five of his six rehab starts and has an 8.14 ERA with the Tides.

Wada, 32, had Tommy John surgery last May. He signed a two-year, $8.15 million contract with the Orioles before the 2012 season but has never thrown a pitch for the Orioles.

Wada's 30-day rehab assignment is scheduled to end Saturday. The Orioles will likely activate him from the disabled list and option him to Norfolk, where he will continue his comeback attempt from surgery.

Going green

Outfielder Chris Dickerson, who jumpstarted environmental friendly initiatives in a previous major league stop with the Cincinnati Reds, teamed up with healthy living company Veritey to distribute 40 reusable 2.2-liter water bottles to his teammates and the Orioles coaching staff. Each bottle was labeled with the player's name.

Dickerson said he did the same thing with the Reds, and he has done it with high schools and universities as well. He hopes the next step is to install a filling station in the clubhouse to increase the convenience of using the bottles.

"A lot of the guys are fired up," Dickerson said. "This is all the water they'll need for the day, and it's portable. The guys that hunt are real fired up about it."
