Spring training is finally here (though big-name free agent Alex Bregman remains unsigned), and MLB teams will start reporting to their camps in Arizona and Florida as soon as Sunday, with the Chicago Cubs' pitchers and catchers the first and the Los Angeles Dodgers' pitchers and catchers soon after.

Seven teams share spring training facilities, so a total of 23 ballparks host spring training games each year. George M. Steinbrenner Field, the Yankees' spring training stadium, will also host the Tampa Bay Rays during the regular season this year, after their ballpark in St. Petersburg was damaged by Hurricane Milton.
