Stewart, ranked No. 32 on MLBPipeline.com's Top 100 Prospects list, enters the game 2-5 with a 2.58 ERA. He has struck out 55 batters and walked 23 in 76 2/3 innings this season. The 19-year old ranks fourth in the Midwest League in ERA and sixth with a 1.15 WHIP.
Frazier, No. 40 on the Top 100, struggled early this season after a hamstring injury he suffered in Spring Training delayed his season debut. As the weather has warmed up, so has he. Frazier enters Thursday riding a nine-game hitting streak, and he is batting .381/.420/.558 with nine home runs in June and July. Overall this season, Frazier is hitting .274/.345/.435 with 10 home runs and eight stolen bases.
Joining Frazier in the Lake County lineup will be outfielder Mike Papi, the 38th overall pick in the 2014 Draft. He helped the University of Virginia to a runner-up finish in the College World Series before signing with the Indians earlier this month. Papi played just two games with short-season Mahoning Valley before being promoted to Lake County on Wednesday. Papi is expected to make his debut with the Captains on Thursday.
In addition to Stewart, a few other pitchers ranked on the Top 100 are scheduled to start Thursday, including Noah Syndergaard (No. 10), Tyler Glasnow (No. 23) and Lance McCullers (No. 43). Glasnow and Class A Advanced Bradenton will face Clearwater in a doubleheader, which begins at 5 p.m. ET. McCullers will lead Class A Advanced Lancaster against Visalia at 9:30 p.m. ET.
Fans can watch Syndergaard on MiLB.TV as he and Triple-A Las Vegas visit Salt Lake at 9:05 p.m. ET. The Mets' No. 1 prospect has had an up-and-down season so far, but he is coming off one of his best start of the year July 6 at Albuquerque and a successful appearance in the SiriusXM All-Star Futures Game on Sunday. Pitching for the U.S. team at Target Field, Syndergaard threw a scoreless ninth inning to earn the save.
