Winning the first quarter has been an indicator of success in this series, and every game the Lynx and Sparks have played this year. But it isn’t the only stat that shows a strong correlation to winning. In every game except Game 1, the team that has won the rebounding battle–both offensive and total–in the 2016 WNBA Finals has come away with the win.

The rebounding battle was a key going into the series, as Minnesota had dominated the glass during the regular season, and figured to have a strong advantage over Los Angeles in that department. In Game 4, that proved to be especially true.

“They killed us on the boards in Game 3,” Seimone Augustus told reporters following Sunday’s win. “If we clean that up, we’re playing a different game. That’s what we did tonight.”

The Lynx won Sunday night’s rebounding battle 41-25 over the Sparks, but most importantly, they snatched 14 offensive rebounds compared to just eight for the Sparks.

“In Game 3, L.A. kept us off the boards,” Sylvia Fowles said postgame. “We did a better job at it tonight. We made a consistent effort for everyone to crash [the boards] today.”

Fowles lead the charge in that regard, pulling down 13 rebounds, including six on the offensive end, both of which were game highs. Her work on the offensive glass translated directly to eight points for the Lynx, and as a team, Minnesota scored 14 second chance points. Meanwhile, the Sparks scored nine points from their offensive rebounds, and in a game the Lynx won by six points, that five point edge was essentially the difference in the game.

“Well, I mean, anybody that understands what it takes to win games, you know that rebounding is at the top of the list,” Lynx head coach Cheryl Reeve remarked postgame.

Rebounding was certainly on the top of the to-do list for the Lynx in Game 4, and as a result, they earned a winner-take-all Game 5 back in their home gym on Thursday night.
