The Mariners acquired Caballero from the Diamondbacks for Mike Leake in the summer of 2019, and he wasn't considered a top prospect coming into the 2023 season. He earned an early shot with Seattle, and while there were just as many ups as there were downs, he was able to remain a key cog on the bench for the majority of the year. He was much more effective against southpaws than he was right-handed pitching; finishing with an OPS of .758 against left-handed pitching compared to a .588 mark against righties. He showed virtually no power against hurlers from either side, however, and his on-base percentage was strongly boosted by being hit 17 times in 280 plate appearances. Even if Caballero is able to cement a spot in the Seattle lineup next summer, it's hard to imagine him helping fantasy rosters outside of the steals category in 2024. Read Past Outlooks
