TheNew York Yankeesfocused on adding depth to their lineup and bullpen at the MLB trade deadline, rather than make a splashy deal. But the deeper roster the team tried to build is being eroded by injuries. UtilitymanAmed Rosariowas placed on the 10-day injured list with a sprained shoulder (the sternoclavicular, or SC, joint, to be exact), the team announced Sunday. He sustained the injury while running into the right-field wall duringFriday's 5-3 lossto theHouston Astros. [Join or create a Yahoo Fantasy Football league for the 2025 NFL season] A nine-year MLB veteran, Rosario was acquired from theWashington Nationalsfor speed and defense, along with a bench bat versus left-handed pitching (.312/.343/.495). He's appeared in four games with the Yankees, batting 4-of-7 with a double and one RBI while playing right field. CatcherJ.C. Escarrawas recalled from Triple-A Scranton/Wilkes-Barre to take Rosario's spot on the active roster. In an earlier stint with the Yankees, he batted .205/.299/.337 with five doubles, two home runs and 10 RBI in 97 plate appearances. Rosario joins another trade-deadline addition, outfielderAustin Slater, on the IL. Slater is expected to be out much longer with a strained left hamstring. Slater,acquired from the Chicago White Sox, will be sidelinedfour to six weeks, according to manager Aaron Boone. Last week, the Yankees also demoted pitcherJake Birdto Triple-A. Bird,one of three relieversthe Yankees acquired at the deadline, gave up a three-run, walk-off homer to Josh Jung inMonday's 8-5 lossto the Texas Rangers. Bird joined the Yankees from theColorado Rockieshours before the July 31 MLB trade deadline, along withDavid Bednarfrom thePittsburgh PiratesandCamilo Dovalfrom the San Francisco Giants. New third basemanRyan McMahonand utilitymanJosé Caballerohave stayed healthy with the Yankees since coming over from the Rockies andTampa Bay Rays, respectively. But both players may want to be extra careful, considering what's happened with their new teammates. The Yankees head into Sunday's MLB schedule with a 62-55 record that has themthird in the AL East, 5.5 games behind the first-placeToronto Blue Jaysand 2.5 behind theBoston Red Soxfor second place.
