Sveum, now the Cubs' manager, will draw on that experience to help his team's youth and potential blossom with the postseason out of reach. That task continues on Tuesday when Sveum's Cubs take on Roenicke's Brewers at Miller Park in the second game of a three-game set.
"It's the challenging part, but that's why you coach," Sveum said. "You don't coach to sit around and do nothing. That's part of the whole process -- is to coach. The bottom line is you're a coach and still teaching and making guys understand certain things, and seeing how they develop and the work ethic and how they handle this whole stage -- that's a big part of it."
Roenicke said it'd be unfair to evaluate Sveum's first year because of the Cubs' current state of rebuilding.
"Sometimes it's tough, and sometimes it's really fun," Roenicke said. "I think there's nothing better than getting a bunch of young guys that have talent and seeing how far you can improve what they do. For a coach, that's about as fun as it gets, when you do it with guys who are hungry, they listen to you. It can be really fun."
The Cubs will add more youth to their roster on Tuesday.
Left-hander Chris Rusin will be promoted from Triple-A Iowa to start for the Cubs, who will need to make a corresponding roster move. Rusin will be making his Major League debut alongside several of his former teammates at Iowa.
"You see people going in and out, and people moving up and down," Rusin said. "It's all about timing, I think. When you get your chance, make the most of it, and that's what I'm going to try to do tomorrow."
In his last three starts at Iowa, Rusin, 25, gave up four earned runs over 18 2/3 innings.
Right-hander Marco Estrada gets the ball for the Brewers. On Thursday against the Phillies, Estrada went five innings and allowed four runs on eight hits. He is winless in 15 starts and six relief appearances this season.
Cubs: Hinshaw expected to join the team on Tuesday
Newly acquired left-hander Alex Hinshaw will join the Cubs on Tuesday. He went 1-1 with a 4.50 ERA in 31 relief appearances for the Padres this season.
"He's a left-handed guy with a good arm, and we'll evaluate him for the next 40 days or so," Sveum said.
Josh Vitters will likely see more playing time than Luis Valbuena over the rest of the season. The Cubs want to evaluate the younger players on their roster.
Vitters is batting .108 in 37 at-bats this season. He hit his first Major League homer in Monday's game.
Brewers: Changes coming to the rotation
Roenicke and general manager Doug Melvin plan to meet on Tuesday to discuss a few changes to the starting rotation in the next few weeks.
Right-hander Shaun Marcum made a third rehab start for Class A Wisconsin on Monday and should be on track to rejoin the rotation on Saturday or Sunday.
Roenicke and Melvin will discuss if Marcum's return means the Brewers take somebody out of the rotation or just stick with six starters.
Randy Wolf, 3-10 with a 5.69 ERA, will be a topic of conversation. Pitchers nearing their inning limits -- Mike Fiers, Mark Rogers and Marco Estrada -- will also be discussed in the formation of the revamped rotation.
