Nicknamed "Eli" by his teammates, Wallach was a five-time All-Star, three-time Gold Glove Award winner and two-time Silver Slugger Award winner. He's the Expos' all-time franchise leader in games played, hits, doubles and RBIs.
Wallach was drafted 10th overall by the Expos in 1979, made his debut the following season and starred for Montreal through the 1992 campaign. A native of California, Wallach went on to play four more seasons in the big leagues with the Angels and Dodgers.
Currently, Wallach is the bench coach with the Dodgers.
"It's an exciting day," said Wallach. "I was surprised and honored to receive the call. I enjoyed my time in Montreal and the Expos fans. While we did contend during my time there, it was disappointing that we never got to a World Series. As good as you might be, nothing is guaranteed in baseball."
For his part, Van Horne was the English voice of the Expos from their inception in 1969 until 2000. He is known for his signature "Up, up and away" home run call, and for his "El Presidente, El Perfecto" quip following the 1991 perfect game by Expos pitcher Dennis Martinez. After moving to the Marlins in 2001, Van Horne called the team's 2003 World Series championship season. He was honored by the National Baseball Hall of Fame with the Ford C. Frick Award in 2011.
"I really anticipated spending my entire career in Montreal broadcasting Expos baseball. For a variety of reasons, it didn't happen. I'm saddened by the loss of the team in Montreal, but I thought the attendance at the exhibition games there this past March was wonderful."
