Join Discord for earlier access: https://discord.gg/HjKxYKdSUy Kelly enters with a 9.20 ERA, 2.25 WHIP, 12 walks, and 5 homers allowed in 14.2 innings. Boyd's ERA is not pretty, but 26 strikeouts to 5 walks gives Chicago the cleaner starter profile. Every Cubs win in their last 10 cleared by 2+ runs, and every Arizona loss in that same window came by 2+.
