According to the Hooks' game notes from yesterday, Mike Foltynewicz is scheduled to start.... Spoiler on Friday.

...So we have more upside in Quad Cities than in Houston. Is this the first time #1 overall picks are on the same minor team? Don't know if Strasburg and Harper ever teamed up.
Steve Chilcott and Tim Foli both played for the Visalia Mets in 1969. I don't know if they ever played together. Chilcott only played 7 games due to injury. Dave Roberts and Bill Almon definitely played together in 1975 and 1976. Dave Roberts and Mike Ivie played together in 1973. Mike Ivie & Bill Almon played together in 1974. Padres almost had 3 #1s on one minor league team.
