Manager Joe Maddon had previously mentioned the possibility of flip-flopping the starts of Shields and Matt Garza, but the situation resolved itself thanks to Monday's off-day and Shields not throwing another bullpen session. Instead, the right-hander replaced his side session with the 13-pitch outing in which he picked up the win against the Marlins.
"Status quo. Shields is fine. He's had plenty of rest since the inning of relief, so we didn't want to mess with it," Maddon said. "[We] just wanted to make sure coming out today, see how he felt. He feels good, so we're staying pat.
"The off-day helps a little bit. [We] pushed it back an extra day. Without the off-day, we may have done something different."
Shields said he was feeling "really good" after the confidence-boosting relief appearance. He skipped a planned side session on Saturday, which ended up allowing him to enter the game when Maddon said he would pitch after closer Rafael Soriano, and between warming up and taking the mound, he threw enough pitches to make up for the lack of a separate bullpen session.
"If I would have had another bullpen [session], that means I'm not throwing tomorrow," Shields said. "[It's] just like normal right now. I feel really good. We have the six-day rotation, so it kind of worked out."
