As part of a new HBO special from Funny Or Die, Ferrell will be at five Spring Training ballparks in Arizona. He's doing so to honor the historic feat of Bert Campaneris five decades ago by playing every position on the field for 10 different teams on the same day.
Ferrell's goal is to honor Campaneris while also helping organizations dedicated to fighting cancer, including Cancer for College.
Cubs pitcher Jon Lester won't be there and was a little miffed. He posted on Twitter: "Bummed to miss the #FerrellTakesTheField fun today but love the cause! Remember, it's hot out there, milk would be a bad choice! @NVRQT
Mike Olt will start at first for the Cubs and then hand over his glove to Ferrell. Did Olt have any tips?
"He's asking the wrong guy," said Olt, who normally plays third base. "I don't know how to play first base, either. He might do just as well. Just have fun with it. That's all that matters."
Asked if he was worried that Ferrell might take his roster spot, Olt smiled.
"I talked to [Anthony] Rizzo about it, and he and I are both a little nervous," Olt deadpanned.
Bryant was starting at third base. It'll be up to him to make a good throw.
"It's exciting -- it's kind of scary, too," Bryant said. "Hopefully, he knows how to catch the ball. I'm sure he does. He's a big target. That might help us out throwing to first."
"Block the ball, keep it in front," Bryant said. "I don't think he'll do as good a job as Rizzo over there. I think if we give him a good throw, he'll handle it."
On Sept. 8, 1965, Campaneris, in his second Major League season, went 0-for-3 playing all nine positions for the Kansas City Athletics in a game against the California Angels.
"It says a lot about their character and a lot about that person and you gain a lot of respect for people who do that," Olt said of Ferrell's charitable efforts. "I think for him doing this, it'll be huge [for the cause]."
Ferrell is no stranger to the Cubs. He's sung during the seventh-inning stretch at Wrigley Field and donned oversized glasses to deliver his best Harry Caray impersonation. Now, he's listed on the team's active roster.
"It's going to be tough," Lester said Wednesday. "It'll probably take him a couple months to recover from that. It'll be cool to see."
Bryant was excited to be part of it, too.
"I think it does put a little more pressure on me to make a better throw," Bryant said. "And I'm throwing to Will Ferrell, too. That's pretty cool. I would've never expected that in a million years playing this game."
When told of Ferrell's plan, Miguel Montero said it was "awesome." Then, it was pointed out that Ferrell will catch in one of the games.
"Poor guy," Montero said, laughing.
"Wear a cup," Montero said.
