Beginning this week, we’ll be previewing the Mariners’ AL West rivals, one per week, and looking at their 2017 performance, 2018 outlook, pitching staffs and position players. We’re starting with the Angels this week, because their flurry of moves means the roster is probably close to complete, and because my personal rule is when you have a list of tasks ahead of you, attend to the least pleasant one first. Tomorrow we’ll look into the starting 9 the Angels will field; Wednesday will cover the pitching, and Thursday will look into their 2018 projections and farm system.
