Good article.
I believe there's a 13 max pitchers rule in the MLB now, meaning 13 position players, which is 5 bench players. Amaya and Tauchman are guaranteed a spot on the bench, so that would leave 3 more spots up for grabs and not 2. There's a lot of solid bench options, I really don't know how they'll go.
I think they definitely will want another utility INF, so between Madrigal, Mastrobuoni, and Bote. Mastrobuoni's MLB and ST results so far don't live up to what the tools and AAA stats suggest are possible. Disappointed in his fielding, and he comes off as a INF version of Tauchman offensively (with more speed) but that hitting just hasn't been there yet and he hasn't offered any power and not a ton beyond Madrigal, he slaps singles to opposite field more than Tauchman it seems. If healthy I think Madrigal gets the edge because of the glove at 3B to compliment Morel.
I think they definitely also want 1 guy who can play 1B and can hit LHP, so a battle between Wisdom and Cooper. Cooper is the more versatile hitter but Wisdom is the more versatile fielder, and they may need him at 3B at some point this season if Morel fails badly defensively or is hurt, though Wisdom has minor league options. Toss up for me there.
I think there's a decent chance they take a second 1B for the bench. When looking at DH vs LHP the options would be Morel with Madrigal at 3B, Gomes, or Wisdom/Cooper if Busch stays in at 1B. Vs RHP the option would be Tauchman and that's about it, so they may decide they want a power option to pair with Tauchman, which means Dom Smith or Mervis. I think Smith gets the edge. I think the Cubs are curious about Smith after the recent hamate bone surgery, as am I. But if Counsell wants to use the DH slot to give regulars a rest then the last bench spot could be an OF like Canario or Peralta, guess we'll see.
