When Wrigley Field opens for the 2019 season, fans will encounter yet another round of changes. But perhaps nothing is more sweeping — and possibly more disconcerting — than the renumbering of every seat in the ballpark.

After 20 years, the home of the Mariners will no longer be known officially as Safeco Field. The naming-rights deal between Safeco Insurance and the Mariners expired after the 2018 season.

The Oakland A’s and the future of the Coliseum is always an ongoing conversation. However, the front office has continued to add upgrades for a better experience at the ballpark.

Despite the team’s setbacks, a new poll found that 3 out of 4 Oakland voters remain strongly supportive of the A’s building a new, privately financed stadium.

The Los Angeles Angels may not be “of Anaheim” for too much longer. The team announced on Tuesday that they’re opting out of their stadium lease with the city of Anaheim.

The Arizona Diamondbacks are going away from natural grass next season. The team announced Friday that it will install synthetic grass at Chase Field in partnership with Shaw Sports Turf.

In June, Diamondbacks President Derrick Hall emailed Phoenix City Manager Ed Zuercher, hoping to discuss “an opportunity” for a partnership between the two organizations.
