Vargas (lat) is scheduled to throw a bullpen session Saturday and is nearing a rehab assignment, Daniel Kramer of MLB.com reports.
Vargas opened the season on the injured list due to a right lat strain, an injury severe enough for him to transfer to the 60-day IL in early April. However, it looks like he's close to making his 2026 major-league debut. If all goes well with his bullpen session and upcoming rehab assignment, Vargas could rejoin the Mariners in mid-August.
