I just had an OL season wrap up where I used only 2020 players. I had a pitching staff of:
Darvish, Hendricks, M. Gonzalez, and Bassitt with a bullpen of:
Urquidy, Curtiss, Hunter, Petit, Strahm, R. Smith, Tropeano.

My team RL gave up 125 HR/162 with 1,204 IP/162 and in the sim gave up 120 HR in 1,466.67 IP.
Individually that shows up as:
Darvish: 205/14 RL & 241.33/14 SIM
Hendricks: 220/27 RL & 273/25 SIM
Gonzalez: 188/22 RL & 227.33/19 SIM
Bassitt: 170/16 RL & 210.33/14 SIM
Urquidy: 80/11 RL & 79.67/7 SIM
Curtiss: 68/8 RL & 77.33/11 SIM
Hunter: 67/5 RL & 70/6 SIM
Petit: 58/8 RL & 64.33/6
Strahm: 56/8 RL & 60.67/11 SIM
Smith: 50/3 RL & 51.33/2 SIM
Tropeano: 42/3 RL & 54/0 SIM
I feel like Smith & Tropeano fit the profile named above, and performed exactly as I'd have expected/hoped with 6 RL HR/162 over 92 IP/162 and 2 SIM HR over 105.33 IP
