"Ohtani and Bieber, then pray for rain" doesn't quite have the right ring to it, but nonetheless it makes the point that Sewell is looking to add at least one SP who is "playoff rotation" caliber and then round out with guys who are at least reputable this year. In terms of young carded talent to offer, we have infielder Abraham Toro (B2) and little-A eligible SP Braxton Garrett (B1).
SPR could also use pitching, as well as help at C and some righties to balance out our very LH outfield. Tucupita Marcano is available- a 21 year old infielder who got exactly 50 PA to lose his E status. He can be kept as little A or can be used as an unlimited 2B/3B/OF.
Both teams are open to trading draft picks and also have an array of guys who have succeeded in the major leagues but are E players this year for various reasons: Masahiro Tanaka, Roberto Osuna, Caleb Ferguson and James Paxton on Sewell, Yonny Chirinos and Jose Leclerc on Springfield.
