The Blue Jays acquired the 28-year-old Tepesch from the Twins in a minor July deal, and after a brief stint at Triple-A, hhe allowed nine earned runs (and six unearned runs) in 15 2/3 innings in four starts with the big club before returning to Buffalo last week. The 28-year-old has a 4.71 ERA, 5.4 K/9 and 3.0 BB/9 over 238 2/3 innings spanning parts of four seasons in the big leagues.
The 26-year-old Santos spent time in the Pirates and Royals organizations before signing a minor-league pact with the Jays early in the 2015 season. He’s produced a 4.07 ERA, 8.1 K/9 and 3.7 BB/9 in 108 1/3 innings in the rotation at Buffalo this year. It’s not immediately clear what role he’ll take with the Blue Jays, but should he stick with them, protecting him on their 40-man roster would prevent him from departing via minor-league free agency this winter. He also hasn’t pitched since last Thursday, potentially making him a useful short-term addition.
