Padres reliever Jason Adam ruptured a tendon in his left quadriceps and was carted off the field Monday, a major blow to San Diego's dominant bullpen.

Adam was injured in the seventh inning of a 4-3 loss to the Baltimore Orioles. One of several All-Star relievers on the team, Adam said he still needs to get an MRI for confirmation, "but that sounds like six to nine months, so the season's probably done."
