Just four Minor League teams have had two No. 1 overall picks on the roster at the same time, but with both Appel and Correa, the River Bandits are the first Minor League club to house consecutive No. 1 overall picks.
Appel, 21, signed with Houston on June 19 out of Stanford. The right-hander made two starts with short-season Class A Tri-City of the New York-Penn League, allowing two earned runs on six hits and no walks while striking out six over five innings.
Correa is the club's second-ranked prospect, according to MLB.com, and is hitting .325 with 24 extra-base hits, 50 runs scored and 48 RBIs in 69 games with Quad Cities.
