**Context:** I've come across the sentence

> そんなわけあるはずない

which I'm assuming parses into

> (そんな)(わけ)(ある)(はずない)

and means something like

> That sort of reason existing cannot be!

or more idiomatically:

> That cannot be!

**Problem:** When I put this sentence into
[OJAD](https://www.gavo.t.u-tokyo.ac.jp/ojad/eng/phrasing/index) I get

> [![enter image description
> here](https://i.stack.imgur.com/CtPKA.png)](https://i.stack.imgur.com/CtPKA.png)

with ある{LH}. But I thought ある had pitch ある{HL}? If I use 有る in place of ある
with OJAD (just to make it extra precise), the problem persists.

**Question:** Does the pitch of ある ever change in contexts like this? I know
that OJAD sometimes gets things wrong, but I just wanted to make sure.
