Two-time Cy Young winner Johan Santana has suspended his bid to pitch in the majors and will try again in 2016, a source told ESPN.com.
Santana has been dealing with a toe infection and became resigned that he would not have sufficient time to ramp up this season to pitch in the majors once that issue is resolved.
Santana, 36, signed a minor league deal with the Toronto Blue Jays in February.
He has undergone two shoulder surgeries since last appearing in the majors in 2012 with the New York Mets.
Santana was pitching in the minors with the Baltimore Orioles last June when he suffered a torn left Achilles tendon. He returned from that injury to make one appearance in January in the Venezuelan Winter League.
