RHP James Shields was disappointed Sunday's game was rained out because he had been pitching well overall, especially his past two starts against the Yankees, and felt the Rays had a good chance to win the series.

"I was ready to go," Shields said. "I feel really good right now, and I wanted to face these guys."

His consolation prize is to start Tuesday's opener in the day-night doubleheader in Boston (where he is 1-7, 7.71 in eight starts) as the Rays remixed their rotation after the postponement.

Shields will replace RHP Wade Davis, who was bumped back to Friday's home game against Seattle. RHP Jeff Niemann, who is 5-0, 1.65 in his past seven starts, will work Tuesday's nightcap, and LHP David Price will face the Red Sox on Wednesday. With an off day today and another Thursday, the Rays won't need any more than five starters.

"We don't want to skip either (Shields or Price), and Niemann's been kind of a hot hand lately, so it just makes sense to go that way," manager Joe Maddon said.
