With the way the current rotation is set up, Alex Cobb is set to be slotted into the position, but Maddon may choose to swap his spot with Matt Moore, who would be pitching the next game.
"I have to talk to [pitching coach Jim Hickey], I haven't talked to him yet," Maddon said. "I don't have any strong feelings about it right now. Part of it is looking into Toronto also, how does that play. ... They're both throwing the ball well right now, it's not like one guy is better than the other, they're both good."
Maddon added that he's been mulling over different ideas for his rotation, complicated further with Jeff Niemann set to come off the disabled list soon. But Cobb, who is coming off his first career complete game shutout, has pitched well over the past month and it could be difficult to remove him from the rotation when Niemann returns.
"We've been sitting down, going over a bunch of different ideas," Maddon said. "We've been working on this whole elaborate sheet that pretty much goes from now until the end of the year and that also includes figuring out how to pop Niemann in there, too. We have all these different thoughts going on, we're not specific yet."
Niemann is set to make his second rehab start with Triple-A Durham and fourth overall on Saturday. In his last start for the Bulls, Niemann went 4 1/3 innings, allowing four runs on 12 hits and three strikeouts.
Maddon also hasn't ruled out starting to roll back the innings that Moore and Cobb have pitched in order to keep his young arms fresh down the stretch by having somebody either skip a start or popping a pitcher, like Niemann, in.
Lately, it hasn't seemed to matter whoever takes the mound for the Rays. The club is on a run that few teams have been on before. In fact, the last four teams to have an ERA as low as Tampa Bay's 3.25 mark have gone on to the World Series, with two teams winning it.
Only one pitching staff has led the American League in ERA, strikeouts and opponent's batting average in the last 25 years -- the 1999 Red Sox. Right now, the Rays with their ERA, 1,045 punchouts and .232 batting average against lead the league in each category.
There are just 221 strikeouts separating the Rays from the American League record, as well, held by the 2001 Yankees. Their 45 double-digit strikeout games are the best by an AL team since 1918 when records were first kept on it, but trail the Nationals by two this season.
"This is a little above and beyond right now," Maddon said about the pitching. "I thought they'd be good, but what they're doing more recently is, I guess, record-setting, historically. I have a lot of faith in all these guys."
