MESA, Ariz. -- Cubs prospect Christian Villanueva broke his right fibula during drills Sunday, and will most likely be sidelined for a few months. He was expected to have surgery Monday.
"It was a ground ball -- I guess he hopped up to jump up in the air and you come back down and that's how it happened," manager Joe Maddon said of the Cubs' No. 26 prospect. "It's just crazy. It's really unfortunate. This kid came in, ready to go."

Villanueva, 24, began last season at Double-A Tennessee, but when Kris Bryant was promoted to the big leagues, Villanueva moved up to Triple-A Iowa. He batted .259 there, hitting 18 home runs and 23 doubles, then played for Obregon in the Mexican winter league, where he hit .322 with nine home runs and nine doubles.
"It's a tough break, literally, for him -- he's such a good kid," Maddon said.
• David Ross, Ben Zobrist, Addison Russell and Jorge Soler won the relay-throw drills Sunday, and each got a star plus some pocket money for their efforts.
"I was so impressed with our guys," Maddon said of the drill. "I'm watching 'Zo,' how well he was moving his feet, and Addison, the ball barely touched his glove. Those are the kind of things that during the course of the season make a huge difference."
Maddon said the drill also illustrates how the slightest bobble can slow things down, giving the baserunner the advantage.
• Some of the Cubs took batting practice and infield at Sloan Park on Sunday to get a feel for the home stadium. The Cubs' first home Cactus League game will be Friday against the Angels.
"It was purely to get the guys out there and give them a test drive," Maddon said.
• The Cubs placed reliever Zac Rosscup on the 60-day disabled list with left shoulder inflammation, although the 60-day clock does not start until Opening Day on April 3. Rosscup, 27, appeared in 33 games with the Cubs last season, posting a 4.39 ERA, but also had two stints on the disabled list last season because of shoulder inflammation.
• Quote of the day: "What helps take you to that next level is purely enjoying -- it's joy, the joy of participation. If you get a bunch of guys who are good, who want to be here, like being here, like each other, I don't know how many wins that's worth, but I know it's worth some wins. Beyond the X's and O's of this camp, a large part of our discussion is how do we make it fun and enjoyable and at the same time pertinent." -- Maddon, on how the Cubs like to come up with ways to keep Spring Training camp interesting
