Santos was outrighted to Double-A Hew Hampshire on Monday, Chris Cotillo of MLB Daily Dish reports. The affiliate concludes its season Monday, so the next step in Santos' own campaign is unknown. In any case, he doesn't seem to factor into the Blue Jays' playoff push, after posting an 8.57 ERA, 2.19 WHIP, and 29:18 K:BB in 21 innings with the big club this year.
