Johan Santana gives up comeback effort
Left-hander Johan Santana, a two-time Cy Young Award winner, has abandoned his comeback bid with the Toronto Blue Jays.
General Manager Alex Anthopoulos said that a toe infection was the primary factor in Santana's decision. He said Santana plans to pitch in winter ball.
Santana, 36, hasn't pitched in the majors since 2012, with the New York Mets. He signed a minor league deal with Toronto in February but never appeared in a game at any level.
He sat out 2011 and 2013 after shoulder surgeries. He signed a minor league deal with Baltimore in 2014, but his season ended last June after a torn Achilles' tendon.
Santana is 139-78 with a 3.20 earned-run average in 12 major league seasons. He was the AL Cy Young winner with Minnesota in 2004 and 2006.
