Sean Guenther DVOA, Advanced Stats, & Fantasy Rankings

Detroit Tigers left-hander Sean Guenther will serve as the team's opener ahead of right-hander Keider Montero for Monday's series opener against the St. Louis Cardinals at Busch Stadium, according to the Detroit News' Chris McCosky. This will be the first career MLB start for Guenther, who should be avoided as a fantasy streamer. The 29-year-old southpaw currently has a 2.25 ERA and 1.00 WHIP with six strikeouts and three walks in six relief outings for Detroit over eight innings pitched. He has not gone beyond two inning pitched in any of his six relief appearances for the Tigers this year, so fantasy managers shouldn't expect him to go very deep at all against St. Louis in this one. This will be Montero's second straight outing in a bulk-relief role. He gave up three earned runs in 3 1/3 innings in the same role last week against the Boston Red Sox.
