The 31-year-old Santos has had a difficult time remaining healthy since being acquired by the Blue Jays in a 2012 trade that sent right-hander Nestor Molina to the White Sox. Santos underwent shoulder surgery that season, battled a triceps injury last year and has missed time with a forearm strain in 2014.
Following his previous DFA, the Jays immediately placed Santos on outright waivers, hoping that his contract — he’s earning $3.75MM in 2014 and has a $750K buyout on a $6MM option for next season — would allow him to clear. That’s exactly what happened, and the Jays sent him to Triple-A with the hopes that he could rediscover his 2010-11 form. He fired 10 2/3 shutout innings in the minors and was promptly brought back to the club, but he’s struggled again in his return. Santos made just two appearances and allowed four runs (three earned) on four hits and a walk in 1 1/3 innings. He surrendered a pair of homers in that time, although he did also record three strikeouts.
Santos, who converted from shortstop to the mound, has consistently shown the propensity to miss bats, but command has been an issue for him. It’s possible that he could rejoin the team in September, but even if that happens, it certainly seems unlikely that Toronto would exercise the club option given his recent struggles.
