Davis continues to impress the Rangers with his ability to throw strikes and his surprising resilience. He picked up the win in two of those games. Oates said Sunday that Rick Helling would start the second-half opener at Arizona and would be followed by Kenny Rogers. Then things got foggy. Oates said he may lean toward starting lefthander Matt Perisho in the third game, Esteban Loaiza in the fourth game and Ryan Glynn, if the blister on his hand is completely healed, in the fifth game after the break.
