Willson Contreras? Even though he's hitting in the low .200s this year, it's hard to see the Cubs dealing him. Catchers with his combination of skills are rare. Contreras, 25, came up as a third baseman and played a fair share of outfield last season, which adds to his value. He would be tough to replace, though the Cubs do have switch-hitting Victor Caratini, 23, waiting in Triple A. Through Monday, Caratini was hitting .339 with three homers and 26 RBIs in 34 games. Caratini also can play first and third base.
