Quick stat count on what the Padres gave up:
CJ Abrams (SS-MLB-21) <- He was the Padres top prospect until he played enough this season. Callup when Tatis went down.
@AAA: 30G, .314, 7 HR, 10 SB, .364 OBP
Gore (RHSP-MLB-23): 13GS, 4.50 ERA, 70 IP, 72 SO, 1.471 WHIP
#1 Hassell III (OF-A+-20): 75G, .299, 10HR, 20 SB (#21 Overall MLB)
#3 James Wood (OF-A-19): 50G, .337, 10HR, 15 SB (#88 Overall MLB)
#14 Susan (RHSP-Rk-18): 7GS, 2.45 ERA
I think the Padres expect to get Tatis Jr back mid-to-late August. That makes CJ Abrams unnecessary this season and the next few, assuming Tatis Jr recovers fully. That is a huge chip to give up and I don't think the Rangers would have someone to compare.
Gore seems like a mid-tier SP, of which we have plenty.
Hosmer/Lowe/Huff/Other.
From a pure ranking perspective, you could argue Hassell would equate to either Leiter or Jung. Wood could be matched to Duran/Smith/Other.
Abrams was obviously the big get. Beyond that, the amount of talent the Padres give up isn't tremendous, IMO. For the Rangers it wouldn't have killed our farm, but for the Padres... Giving up the #1, 2, & 3 prospects in a farm system that is otherwise pretty thin, will be hard to absorb. Soto in the OF for 2+ years makes give up the OF prospects easier, but still pretty deep cuts.
I can see where the Rangers were likely still having conversations but ultimately walked away. If we had gotten Castillo, getting Soto and Bell would have turned things around... but that was killed when the team tanked over the past 3-4 weeks.
