The Philadelphia Phillies optioned Zach Eflin following his start on Friday night, activating J.P. Crawford from the disabled list.
Due to Philadelphia's schedule, Eflin won't miss a start and they'll benefit from having a five-man bench.
However, Eflin, who is having a career-year, will miss out on nine days of service time and lose $20,000.
"While this transaction on the surface seems purely administrative, it caught us by surprise and is tremendously disappointing," agent Tim O'Connell told The Athletic. "Major-league starters have a strict routine that they adhere to that allows them to be successful; this roster move affects that. While the club may feel that they are doing what's best for the organization, they also lose sight of the human element and how it will affect the player."
