The upcoming tax year is 2018, not 2019, even though you file in 2019.
The answer is "probably". For 2017 Oregon said: "You can claim itemized deductions on your Oregon return even if you don’t itemize on your federal return. If you itemize for Oregon only, fill out a federal Schedule A for Oregon purposes.".
The 2018 tax year Oregon rules have not been published yet, but assuming no change in Oregon tax law, it will probably be the same for 2018.
