Verlander is recovering from surgery on his abdomen in early January. He's trying to tone it down this spring and Tigers rookie manager Brad Ausmus says Verlander is mostly setting his own pace.
Verlander said: "I feel really good. I don't feel any pain but I am just taking everything in stride. Everything is on track for Opening Day."
Verlander was slated to throw 40 pitches Saturday, but instead threw 41.
It's the third time Verlander has thrown off the mound since coming in ahead of the official pitchers and catchers reporting date, but it is the longest stint he's had.
