Waguespack will start Sunday's game against the Royals as an opener, Chris McCosky of The Detroit News reports.
It'll be the first start of the season and 15th of Waguespack's MLB career, with most of those coming in 2019 when he was working out of the rotation with Toronto. The right-hander is in the midst of his best big-league campaign with a 1.95 ERA, 0.83 WHIP and 16:9 K:BB across 27.2 innings out of the bullpen, though his 4.71 xFIP indicates regression could be on the horizon.
