Chris Volstad, who will make his first start for the Cubs since May 17 on Tuesday, was a teammate in a summer league when he was a high schooler with Cubs lefty Scott Maine. The two played for different high schools in Florida, and faced off in a game at Roger Dean Stadium in Jupiter. Maine still sounded upset about losing the game, because a run scored on a wild pitch, although Volstad was sure it was a passed ball.

"It's just funny that we ended up on the same team," Maine said.

Volstad was eager to get back on a big league mound after making eight starts at Iowa, where he was 2-3 with a 4.44 ERA. In eight earlier starts with the Cubs, he was 0-6 with a 7.46 ERA.

"I'll be the first to admit I definitely needed to go down there," Volstad said. "I had some things I needed to work on and things I needed to iron out. I've done it before, but this time was different. I took the time I needed down there to work on some things. Nothing mechanical really but my approach and in-game stuff."

• The Cubs have reportedly signed 16-year-old Dominican shortstop Frandy De La Rosa for $700,000. In accordance with the new Collective Bargaining Agreement, the international system now operates with money pools and penalties for teams that exceed their pools. For the 2012-13 signing period, every team will have the same pool of $2.9 million. Starting in 2013-14, the pools will be based on the prior season's winning percentages, with a range of approximately $1.7 million to $4.8 million.

• Outfielder David DeJesus was day to day with a stiff neck, but was expected back in the Cubs lineup on Tuesday.

• Double-A Tennessee second baseman Logan Watkins and pitcher Nick Struck were named the Cubs' Minor League Player and Pitcher of the Month. Watkins, 22, batted .352 with three doubles, three triples, one home run and 11 RBIs in 23 June games. He had a season-high 13-game hitting streak, in which he batted .375, from June 13-30.

Struck, 22, was 4-1 with a 2.45 ERA in five June starts, walking eight and striking out 23, while limiting the opponent to a .181 batting average. He gave up three or fewer runs in all five of his outings and recorded three quality starts.

• Cubs pitcher Ryan Dempster and Braves catcher Brian McCann met with families of children with 22q at Turner Field on Monday. The visit is part of The Dempster Family Foundation's effort to raise awareness of the disorder.
