Crawford, the Tigers' No. 4 prospect, is scheduled to start for the Whitecaps and is coming off the best start of his career, also against the Dragons. He threw seven scoreless innings last Friday in Dayton, setting career highs for innings and strikeouts (nine).
Crawford is just shy of qualifying for the ERA title in the Midwest League, but his mark of 2.16 would rank fourth if had thrown enough innings to be eligible. He has struck out 41 batters and walked 12 in 41 2/3 innings.
While Crawford has excelled in his first full professional season, Ervin has struggled. The Reds' No. 2 prospect is hitting .211/.275/.302 with 17 stolen bases and one home run in 50 games this season.
Ervin, ranked No. 91 on MLBPipeline.com's Top 100 Prospects list, went hitless Wednesday, but is seemingly turning it around. In the last two weeks, he hit his first homer of the season and is hitting .267/.308/.400 in 14 games.
Dayton will turn to right-hander Ismael Guillon, the Reds' No. 9 prospect, to face Crawford. He enters the game 3-0 with a 2.91 ERA this season. He has struck out 51 batters and walked 21 in 46 1/3 innings.
Thursday's Minor League schedule also includes a few pitchers ranked in the Top 100 who are slated to start, including Jon Gray (No. 13), Henry Owens (No. 26), Zach Lee (No. 54) and Trey Ball (No. 83). Fans can watch all four on MiLB.TV, beginning with Owens and Double-A Portland hosting New Britain at 11:00 a.m. ET.
