MILWAUKEE -- After Nolan Arenado posted a successful batting practice session Friday night, his locker at Miller Park was empty Saturday morning as the third baseman returned west to begin a rehab assignment at Triple-A Colorado Springs.
Arenado, sidelined since May 24 with a fractured middle finger on his left hand, was scheduled to start Saturday for Colorado Springs, Rockies manager Walt Weiss said. Arenado will go day to day after that, and though there is no exact timetable for his return, the Sky Sox are scheduled to be home until Thursday.
"We'll see how it goes," Weiss said. "He's been out for a while, so it's tough to say, 'This is how it's going to go.' We'll check with him day to day and see how he responds to playing and going game speed and all those things that go along with it."
Meanwhile, outfielder Carlos Gonzalez has made some progress after surgery to remove a tumor from his left index finger on June 10. Weiss said the stitches had been removed but Gonzalez was still recovering.
"He's starting to just take dry swings with the bat. He hasn't taken any batting practice or anything; he's just swinging the bat," Weiss said. "He's had the stitches removed, but it's still a pretty good scar there, and the incision was pretty sizable, so just working around that."
