The field is almost 550 square yards smaller than the next smallest, Portland’s Providence Park. At its listed measurements, it ties D.C. United’s home of RFK Stadium and Providence Park for the shortest, and ties Minnesota United’s home of TCF Bank Stadium for the narrowest.

By comparison, Mercedes-Benz Stadium will have a playing surface of 115 yards long by 75 yards wide.

Because the field at Yankee Stadium is significantly smaller, the players are closer together, which limits the room they have to move. It can take away long through balls for forwards to run onto because goalkeepers don’t have to run as far to catch or parry those attempts.

Atlanta United likes to push its fullbacks up the flanks and into the attack. Because the field is so narrow, they may end up on top of the midfielders and forwards with little room to run off their shoulders and down the sidelines.

“It’s a tough place to go,” Atlanta United fullback Tyrone Mears said. “The dimensions of the pitch are very tight. We’ve got to be switched on. We will have to play a lot quicker because we will be closed down a lot faster.”

When 22 men are on a field that small, there will be contact, which may be why, according to stats provided by Elias, the second-most number of yellow cards in MLS were issued in Yankee Stadium in 2015 (71, second to the Colorado Rapids’ Dick’s Sporting Goods Park’s 72) and 2016 (69, second to Providence Park’s 69.) Providence Park also features a small field. Considering that Atlanta United players already have three red cards (one rescinded), that could be another factor in the game’s outcome.

Atlanta United manager Gerardo Martino said the coaching staff learned of the Yankee Stadium field dimensions and practiced Thursday on a field the same size. He didn’t say what those dimensions were.

“I’ve watched games there,” he said. “It’s really noticeable, the dimensions, that it’s narrow. It could presents some challenges to the game.”

SCOUTING NYCFC

Coach: Patrick Vieira.

Record: 4-3-1.

Previous game: 3-2 win over Columbus.

Last 5: W-L-W-L-W.

Three players to watch:

David Villa: Arguably the best goal-scorer in MLS, the 35-year-old Spaniard has more than 40 goals in MLS in addition to the more than 200 he scored in Spain.

Sean Johnson: The Atlanta native was traded from Chicago to Atlanta to NYCFC in the offseason. He has been steady in goal. He has eight starts with two shutouts this season.

Andrea Pirlo: The Italian midfield general seems to be gradually getting phased out of NYCFC's plans. Never quick, at 37 years old the passing maestro has become a defensive liability.
