New York Yankees outfielder Harrison Bader likely will begin the season on the injured list with a strained left oblique.Yankees manager Aaron Boone said Bader, injured on a swing during an at-bat in spring training on Wednesday, went for imaging tests on Thursday that confirmed he will need time to recover. With no timetable for a return, a spot on the Opening Day roster is in jeopardy.Bader’s injury comes after left-handed starter Carlos Rodon, 30, was diagnosed with a left forearm strain and will not throw for seven to 10 days, general manager Brian Cashman said. Rodon, Tommy Kahnle (biceps tendinitis) and Lou Trivino (elbow ligament sprain) are expected to start the season on the IL, Cashman said.
