A timetable for the slugger's recovery won't be determined until lab results are completed. Analysis: The best player on a dismal 2019 Orioles team, Mancini set career highs with 35 homers and 97 RBIs while batting .291 last season. He'll obviously have a hard time duplicating those numbers in 2020, though the good news is the surgery was deemed a success and the Orioles are expecting to return at some point this season.
