You're right. Doesn't change the fact that Volquez has double the amount of BBs as Leake and has surrendered quite a few more home runs than Leake this year as well. Obviously, xFIP is not telling the whole story here.
Even if you compare Volquez's last full season with Leake's rookie year, Volquez still walked almost double the amount of batters as Leake. In Volqeuz's best year, 2008, he only surrendered 14 home runs, and he has 6 already this year and we're not even 3 weeks into the season.
