Thomson said he isn’t sure how long he is going to use the six-man rotation.

“Once for sure and then we’ve got some other ideas how to attack this thing as we move forward,” he said.

Philadelphia starters lead the majors with 687 1/3 innings pitched. Sánchez is up to 150 2/3 innings, and Wheeler is at 144 2/3.

“Just getting some of these guys some extra rest cause we’ve been grinding on them pretty hard all year,” Thomson said before the opener of a four-game set against the Nationals. “The one downside to it is you’ve got to take somebody out of your bullpen, so you’re a little short there but we’ll just have to figure it out.”

Nola hasn’t pitched in the majors since May 14. He posted a 2.19 ERA in three rehab starts with Triple-A Lehigh Valley while striking out 17 batters in 12 1/3 innings.
