Cardinals’ left-hander Quinn Mathews will make his MLB debut on Saturday against the Blue Jays.

The 25-year-old hurler has made 19 starts at Triple-A Memphis this season, registering a 3.13 ERA, 1.14 WHIP and a 111/52 K/BB ratio across 92 innings of work. His strikeout upside could make him an intriguing addition in deeper mixed leagues, though his elevated walk rate does lead to risk in the ratio departments as well.
