Instead, McGehee is with the big league Cubs, hoping to help them get to the postseason.
McGehee was one of four players called up from Triple-A Iowa on Monday, the first day teams could expand their rosters beyond 25.
The Cubs recalled infielder Micah Hoffpauir and pitcher Michael Wuertz, and purchased the contracts of McGehee and catcher Koyie Hill. They also activated pitchers Angel Guzman and Jon Lieber, who were both on the disabled list.
In another procedural move, the Cubs placed Rich Hill on the Major League disabled list and moved pitcher Chad Fox from the 15-day DL to the 60-day DL. Hill has been sidelined with back problems while Fox was rehabbing from a sore elbow.
Of the group, McGehee was the only one who had never stepped onto Wrigley Field until Monday. The right-handed hitter, who can play third and first base, opened some eyes in Spring Training.
"I think it helped just as far as being around and seeing me play more," he said of his spring. "You never know what people are thinking or what's going to happen. You do your job, and if they think you're deserving, you'll get a chance, and if not, you try again next year."
He's been leaning on Hoffpauir since they got the news Saturday.
"I've probably asked a lot of stupid questions that he's had to answer in the last couple days," McGehee said.
Hoffpauir, a left-handed bat who can play first or the corner-outfield spots, batted .362 at Iowa with 25 homers and 100 RBIs in 71 games.
"It was fun," Hoffpauir said of his success. "You have to tip your hat to the guys hitting around me to get on base."
This is his fourth stint with the big league team. Hoffpauir has a .378 average with six doubles in 19 games with the Cubs. His success during his brief big league days helped.
"I had no worries then," Hoffpauir said. "I think that had a little thing to do with it, and tip your hat to the hitting coach down there, Von Joshua. We've been working together, and he's done a great job, and he knows what he's doing."
Guzman is back after undergoing Tommy John elbow reconstruction surgery on his right elbow Sept. 6. He was 1-0 with a 1.59 ERA in seven rehab appearances at three different Minor League levels. Radar guns have clocked the right-hander's fastball at 96 mph.
"That's my last trip to the DL," said Guzman, whose career has been shortened because of injuries to his shoulder, as well as his elbow. "I don't even think about it; I don't talk about it; I try to stay positive.
"I've been working hard and putting in a lot of effort and I'm getting good results," he said. "I just have to stay on the same plan and do what I've been doing for the last 10 months."
Wuertz went 1-1 with a 3.55 ERA in 37 relief appearances for the Cubs before he was optioned to Iowa on July 11. In 17 relief outings, he was 0-1 with four saves and a 3.60 ERA.
