BOSTON -- Heading into Tuesday's twin bill, manager Joe Maddon said he would wait until afterward to decide on which order he would start James Shields and Jeff Niemann for Sunday's and Monday's games.

Maddon said the decision regarding which of the pair would pitch on Sunday with regular rest would be determined by how each of the pitchers did on Tuesday. Well, both did fine. Each threw a complete game against the Red Sox and each used 114 pitches while doing so.

Maddon will now wait until Friday to announce who will start against the Mariners on Sunday and who will face Justin Verlander when the Tigers come to Tropicana Field on Monday.

"We're just checking everything out right now," Maddon said.

Maddon wants to see how each pitcher recovers from their respective outings.

"It's about what happens [during their recovery period]," Maddon said. "So let's go TBD for now. ... One of those two guys will pitch on Sunday, the other will pitch on Monday. ... I don't think they know about Verlander yet."

Maddon has tinkered with the starting rotation over the last month, leaving most of the starters well rested, but cranky to get back on their regular pitching schedules.

After pitching with five or six days' rest lately, Shields was asked if he could pitch with just four days of rest.

"I haven't done it in a while, so I don't know," he laughed. "I definitely can, for sure. I've been changing my routine around a little bit the past couple of starts to wear my body down some to stay ready."

Both Shields and Niemann allowed three hits Tuesday.

The way they pitched "didn't make it any easier for [Maddon to make a decision], but it's a good problem to have," Shields said.

Rodriguez not afraid to get hit by pitch

BOSTON -- Fans watching Sean Rodriguez during Tuesday's doubleheader will likely remember the infielder one of two ways: The guy who hit into a triple play or the guy who always seems to get hit by a pitch.

Rodriguez grounded into a 5-4-3 triple play in the fourth Tuesday night, which he noted was the first time he's done so at any level.

"As soon as I hit it, I'm like, 'Oh no,'" Rodriguez said with a smile.

Rodriguez allowed that he would much prefer to be remembered as the guy who gets hit by pitches a lot.

Jon Lester hit Rodriguez on the left knee in the first game, sending him reeling to the ground in pain, but he did not leave the game, and Matt Albers hit him on his left thigh in the second game.

Rodriguez has been plunked a team-high 12 times and noted that he will take the free base if a pitch is headed his direction.

"I don't like to move," Rodriguez said. "[I] have to find a way to get on. ... You can watch the videos of when I get hit, and 90 percent of the time, I'm not moving out of the way. If they're going to hit me, they're going to put me on base."

When asked about how much having a baseball smashing into his body hurts, Rodriguez smiled.

"Just at that moment," he said.

However, you won't see Rodriguez rub where he got plunked, except in rare instances.

"Unless they hit you in the knee and you can't feel it [like in the first game of Tuesday's doubleheader]," Rodriguez said. "Then you have to rub it a little bit. [Otherwise] I never like to give the pitcher satisfaction. ... [Sometimes] I'll see guys get hit in a nice simple spot and I'm like, 'Come on, dude, you're just delaying the game.'"
