Two trademarks about the WNBA. Timid bookmakers afraid to put out overnight lines and the occasional weird scheduling, which we have here. 
There is one game today: Los Angeles at Dallas. Start time is 10 in the morning Los Angeles time. That solidifies my opinion to Under. 

The Sparks are better-coached and stronger defensively under Curt Miller, who coached Connecticut to the Finals last season. They have held two of their last three opponents to fewer than 67 points. 

LA, though, is a below average shooting team from the floor and from beyond the arc. The Sparks have just started getting injured players back. They are a team in transition. 

Dallas has gone Under in four of its last five games. 

The Wings are second in points, averaging 86.3. Hence the high total. However, the Wings rank 10th in field goal percentage and are last in 3-point percentage. I'm expecting the savvy Miller to slow the tempo. The very early mid-week start time certainly isn't going to help the Over.
