Shohei Ohtani is putting his historic contract to good use -- the Dodgers superstar just snagged a ritzy mansion in Los Angeles for $7.85 million ... a place formerly owned by comedian Adam Carolla.
Details on the deal were released this week ... with the L.A. Times reporting the Japanese two-way athlete is the buyer of the La Cañada Flintridge digs.
The pad -- built in 2013 -- is perfect for a guy like Ohtani.
