Let's talk about 1B.
Guzman has been called up.
For the season:
Guzman: .193, 8 HR, .282 OBP, 68 G, 65 K, 25 BB
Forsythe: .228, 7 HR, .329 OBP, 97 G, 95K, 43 BB
Guzman is 24 and hit .235, 16 HR, last season in 123G.
Heineman is 26 and is hitting .184, 0 HR, in 12 G
I believe Forsythe was signed for $2M.
What do you want to see from Guzman the rest of the way, to feel he is your starting 1B in 2020? He did well in AAA, after being sent down. You likely could get Forsythe for another year at $2M. I think if he can go about .250 with some HRs, I'm good. He is still young.
Forsythe as a Util guy is fine... I just don't think signing a 1B is necessary.
I think Santana has move value than being a full-time 1B. Whether you feel 3B, 2B or CF, 1B would seemingly be the least valued role for him.
