Team president Chris Antonetti described as “life-threatening” on August 13.
Cleveland Clinic doctors determined Martin had a bacterial infection that entered his bloodstream and created toxins that damaged his internal organs, compromising their function.
Antonetti, manager Terry Francona and several players visited the hospital Thursday, when Martin was sitting up in a chair and in good spirits.
Antonetti said Martin is eager to return to playing baseball, but there’s no set plan in place. Martin will undergo a series of checkups with doctors this week to monitor his recovery process.
Martin released a statement on Twitter Sunday night, thanking everyone for their support. He also said he is “looking forward to rehab.”
