The Cubs released Lobaton on Monday, Maddie Lee of NBC Sports Chicago reports.
Lobaton inked a minor-league deal with Chicago in mid-July and earned a spot in the Cubs' 60-man roster pool, but he never received a callup to the big club after reporting to the organization's alternate training site. He's unlikely to catch on elsewhere before the 2020 season ends, so Lobaton will presumably set his sights on signing a minor-league deal with the Cubs or another organization over the winter.
