I feel like I’ve been copying and pasting this everywhere but here we go… 
Dubai 1000 is mandatory for Leylah this year having skipped Doha 1000 last year and being ranked high enough for direct entry. The WTA Rulebook does not allow a player with direct entry to skip the same non-mandatory tourney (Dubai and Doha alternate 1000s) in consecutive years. Therefore, it was logistically sound for Leylah to do the entire 3-tournament Middle East swing then take a 1-week break (Monterrey week) before the Sunshine Double. One might ask then: she had early exits in all ME tourneys, why not take a WC into Monterrey? Because she presumably is doing Charleston after Miami then BJK qualifier in Vancouver. She would essentially be doing 8 tournaments back-to-back 8x which is just asking for trouble.
