Giants manager Bruce Bochy, who will manage the NL squad, made the announcement on Tuesday, prior to a doubleheader between the Cubs and Giants.
"It's a wonderful honor," Quade said on Tuesday. "I wish I was calling him to ask him to come with me. That's what I'd like to do someday. That was a real nice surprise."
Quade has joked that Bochy and his staff owed him a case of wine, after the Cubs beat the Padres at the end of last season, which helped the Giants get to the postseason.
"They were pretty happy when we went in there and beat the Padres last year," Quade said. "This is way above any case of wine or any case of wine I'm capable of drinking. It's a great event, and I'm flattered to be going."
Quade, 54, replaces Jim Riggleman, who was named to the NL staff, but was dropped after he resigned from the Nationals last week. In May, Bochy named Riggleman and Arizona manager Kirk Gibson to the NL staff. Bochy's San Francisco coaching staff of Tim Flannery, Mark Gardner, Roberto Kelly, Hensley Meulens, Dave Righetti and Ron Wotus will all be on hand.
Quade took over the Cubs on Aug. 23 and guided the team to a 24-13 record. This year, he's had to deal with injuries to several key players, including starting pitchers Andrew Cashner and Randy Wells, who were placed on the disabled list after their first starts.
After the first game of a Tuesday doubleheader, the Cubs were 32-47, 12 games back in the NL Central.
