He had 16 home runs, 16 stolen bases, and 102 RBI.
Christenson was promoted to bench coach with the Athletics for the 2018 season.[7]
Christenson generated controversy in August 2020 after appearing to perform a Nazi salute after a game. Pitcher Liam Hendriks sought to correct him by pushing his arm down and saying "No, no, no straight arm!"; Christenson, realizing his mistake, laughed and briefly repeated the gesture.[8][9][10] Christenson issued an apology the next day, stating “My gesture unintentionally resulted in a racist and horrible salute that I do not believe in. What I did is unacceptable and I deeply apologize.” The A's responded with a statement: "A's bench coach Ryan Christenson greeted players with a gesture that looked like a Nazi salute. We do not support or condone this gesture or the racist sentiment behind it."[11]
On December 3, 2021, Christenson was hired by the San Diego Padres to serve as the team's bench coach for the 2022 season.[12] On February 3, 2023, Christenson was promoted to "associate manager."[13]
Following the hiring of Bob Melvin as the 41st manager of the San Francisco Giants and his departure from the Padres, on November 10, 2023, it was announced that Christenson would be replacing Kai Correa as bench coach for the Giants for the 2024 season.[14]
