Extra bases

• Reliever Brian Schlitter began his rehab assignment on Thursday with the Cubs' Rookie League team in Mesa, Ariz., and he pitched one inning. Schlitter has been sidelined since Aug. 9 with right shoulder inflammation, and he had been rehabbing at the Cubs' Spring Training complex. There is no timetable for his return.

• Class A Kane County has set a single-season franchise record for home wins following Thursday's 7-3 victory over Clinton, which was their 51st at home. The Cougars have surpassed the 2001 team, which compiled a 50-20 home mark en route to winning the Midwest League championship. The Cougars now have won 84 games this season and are 51-15 at home, which leads both Major League and Minor League Baseball.

With 11 regular-season games remaining, the Cougars need five more wins to break the franchise record for most in a season, set by the '01 Cougars, who went 88-50 during the regular season.

• With the help of two of the Cubs' clubhouse attendants, Luis Valbuena fulfilled the Ice Bucket Challenge for ALS on Friday in the shower. He was challenged by coach Franklin Font's daughter, Veronica, 20, and another friend in Venezuela. Valbuena's reaction?

"It was cold," he said.
