The Seattle Mariners placed ace right-hander Felix Hernandez and rookie right fielder Mitch Haniger on the 10-day disabled list Wednesday.
Hernandez, who is dealing with inflammation in his right shoulder, allowed four runs and six hits in two innings of Tuesday's 19-9 loss to the Detroit Tigers. The 2010 American League Cy Young Award winner and six-time All-Star owns a 2-2 mark with a 4.73 ERA in five starts this season.
