Last year, we did not have a 9 game west coast trip, but we had this:
We won 6 straight v NYY and KCR, then went 3-3 @ OAK & LAA. Later, we went on a road trip and lost 2/3 to CWS and went 2-1 v SEA. (Total 5-4 on West coast)
2020: we played no games vs ALC or ALW.
2019:
1-3 @ SEA

I didn't remember there being so many split west coast trips over recent years, and we did better than I remembered.
