Now that Fernando Tatis Jr. has been placed on the injured list, the San Diego Padres hope their electrifying shortstop won’t be sidelined too long. Tatis should be able to avoid surgery on his left shoulder, the team said a day after he slightly dislocated it taking a hard swing. An MRI on Tuesday showed a slight labral tear and the Padres put the 22-year-old Tatis on the 10-day IL. General manager A.J. Preller said the club wasn’t ruling out anything, including Tatis’ possible return when he’s eligible. Meanwhile, the Cincinnati Reds and Detroit rookie Akil Baddoo are both off to smashing starts this season.
