The Padres plan to place Strahm on the 10-day injured list Wednesday due to an unspecified issue, Jeff Sanders of The San Diego Union-Tribune reports.
San Diego will confirm the transaction shortly before Wednesday's series finale with the Rockies that begins at 3:10 p.m. ET, at which time more information about Strahm's injury should become available. The right-hander had spent most of the season on the 60-day IL while recovering from the right knee surgery he required last October, but it's unclear if he suffered a related setback. Strahm made his first five appearances with San Diego as a reliever before he was deployed as an opening pitcher in Tuesday's contest. He was the pitcher of record in the Padres' 7-3 loss, giving up a run on four hits and no walks over 1.1 innings before turning the game over to the bullpen.
