Alou hasn't participated in an All-Star Game since managing the NL squad while manager of the Montreal Expos 10 years ago. He was a three-time All-Star as a player, in 1962 with the Giants and in 1966 and '69 with the Atlanta Braves.
This will be the first All-Star coaching assignment for Alou, who is in his third year as manager of the Giants and his 13th overall as a Major League manager.
"I love the first-time All-Star," La Russa said. "The times I've been there, whether it was myself in '84, or as a manager when you pick those first-time guys, they light up differently than anybody else."
Alou has won the most games of any Latino manager in Major League history and is ninth among active managers in wins.
"It is an honor," said Alou. "I've been asked to coach two other years, but I went fishing instead. But Tony and I are long-time friends, and he asked me over the winter to coach. I'm not sure what I'll be doing during the game -- maybe coach second base."
Yost, in his third year as manager of the Brewers, is the first Milwaukee manager to serve on an All-Star staff since Phil Garner in 1995.
Yost was a 12-year member of Bobby Cox's coaching staff with the Atlanta Braves prior to joining Milwaukee, first as bullpen coach and then as third base coach. This is his first All-Star coaching assignment since joining the Brewers, but as an Atlanta coach Yost was part of the NL All-Star staff in 1992-93, 1996-97 and 2000.
Yost played professionally from 1974-1987 and played parts of six seasons with the Brewers, the Texas Rangers and the Montreal Expos from 1980-85.
La Russa, who has the most wins among active managers and is fourth all-time in managerial wins, also has invited Dave Duncan, Marty Mason, Jose Oquendo, Joe Pettini, George Kissell and Dave Lackey to handle batting practice and other field duties.
Trainers Barry Weinberg of the Cardinals and Mark Mann of the Cincinnati Reds will complete the N.L. All-Star staff.
