Yarbrough is one of the leading candidates to log starts during the absence of Blake Snell (elbow), Juan Toribio of MLB.com reports. The lefty is expected, however, to work as a bulk reliever behind opener Diego Castillo in his next scheduled turn Friday in Toronto, per Marc Topkin of the Tampa Bay Times.
Yarbrough is naturally well stretched out after filling a variety of roles thus far this season, including spot starter. The 27-year-old southpaw has put together a respectable 3.93 ERA and stellar 0.93 WHIP while posting an 8-3 record across 16 appearances (five starts) at the big-league level in 2019.
