out of the ballpark
1. Far greater in number, size, or scope than what was predicted, expected, or suggested. I knew that this would get some media attention, but the amount it has received has been out of the ballpark! They said the repairs should only cost a few hundred dollars, but the final bill was way, way out of the ball park!
2. Extremely well or successfully. (Used almost exclusively in the phrase "hit (something) out of the ballpark." Great job on that report, Jacobs—you really hit it out of the ballpark! I'm pretty sure I hit that test out of the ballpark.
