The New York Yankees placed reliever Ian Hamilton on the 15-day injured list Wednesday with a right groin strain.
The 27-year-old right-hander is 1-1 with one save and a 1.23 ERA in 16 appearances out of the bullpen this season.
Hamilton has struck out 30 and walked nine without allowing a home run in 22 innings.
The Yankees recalled left-hander Nick Ramirez from Triple-A Scranton/Wilkes-Barre in a corresponding transaction.
Ramirez, 33, made three relief appearances for New York earlier this season and posted a 2.84 ERA with no decisions.
