Giles struck out two batters in a perfect ninth inning during Sunday's 3-1 loss to Seattle.
Giles was reinstated from the paternity list on Sunday, and the Blue Jays likely just wanted to get him loose again considering he'd appeared in only one game since Aug. 16. The 28-year-old righty lowered his ERA to 1.76 with a 67:15 K:BB.
