Sauer, 26, was a second-round pick by the Yankees back in 2017 but didn't make his major league debut until last year as a member of the Royals after being plucked from the Yankees in the Rule 5 draft. He made 14 appearances for Kansas City last year but struggled to a 7.71 ERA in that time. He walked (11) more opponents than he struck out (9) and surrendered three homers in just 16 1/3 innings of work.
Rortvedt joins the Dodgers for the first time since being acquired by the club as part of a three-team trade with the Tampa Bay Rays and Cincinnati Reds on July 31. The Dodgers added Rortvedt to replace Hunter Feduccia as the third catcher on their organizational depth chart. He now gets a chance with the MLB club as Will Smith deals with a right-hand injury after being hit by a foul ball.
