Melancon (forearm) successfully underwent pronator surgery Tuesday, Alex Pavlovic of NBC Sports Bay Area reports.
Melancon's season was cut short when he decided to undergo to repair an issue which plagued him throughout the campaign. His rehab timeline is only 6-to-8 weeks, so he should be ready to go when spring training rolls around next season. Sam Dyson will close out the season as the Giants' ninth-inning arm.
