(Detroit, MI)  --  One of the hottest hitters in the American League is being treated after suffering an injury.  Mariners rookie outfielder Mitch Haniger had to leave last night's game against Detroit early because of an oblique strain.  Haniger was lifted in the third inning by manager Scott Servais after he winced in pain on a single up the middle.  Haniger could be out at least four weeks.
