According to Bruce Levine of WSCR-AM and 670 The Score (who spoke with Blue Jays broadcaster Buck Martinez), the Chicago Cubs have asked the Blue Jays about the availability of closer Ken Giles.
Previously, Levine had speculated that the Cubs could look to trade for Giles should he be made available by the Blue Jays at some point this season. At this point, no other reports have linked Giles to the Cubs.
Giles, 28, has been more or less unhittable so far this season, pitching to an ERA of 1.47 in 18.
