Just look at the numbers already this season between Detmers and Soriano.
Detmers already about 1 full fWAR above Soriano in the same amount of innings this season. Detmers also comes with a better K/9 (10.44), BB/9 (2.74) and FIP (3.35) over Soriano (9.29), (4.17), and (3.79).
Regardless, I'm also happy with acquiring Soriano and like I said previously, if he could lower the BB/9 here and pitching under Pete Walker, he could move to the next level and perhaps be a 4+ WAR arm for the Jays.
I just think Detmers comes with more upside - like's he's capable of possibly putting up a Jesus Luzardo 2025 type season (5+ WAR season) with his stuff and strikeout ability.
