I'm guessing he earned it. While his inventions aren't as eye catching or obviously powerfully as Metal Kight's are, it actually takes more effort to make smaller, but still effective weapons. I suspect his rank may be based more on his strategic and tactical skills than anything else. He seems to be the default leader for the S-Class, despite others being stronger.

Honestly, you really shouldn't rely too heavily on the rankings for judging strength. The system used to figure them out seems to be based on more than just strength, or even effectiveness as a hero. Most likely there are a lot of factors, possibly including how much they're willing to follow orders and work with the HA, amongst other things. Obedience being a factor might explain why Metal Bat is so low ranked, anyway.
