Ketel Marte put together an incredible postseason in 2023. A .329 batting average, 11 RBI, 10 extra base hits, setting an MLB record 18 game hitting streak (started in 2011). Absolutely phenomenal. No one expected him to put up numbers like that over the course of a full season (a .415 BABIP was unlikely), but given that he was going to be just 30 years old on Opening Day, there was hope that it would transfer over and continue through the 2024 season.
To say that it did overall would be something of an understatement. You can see the numbers above.
