Opening Night was Sunday, but for the other 28 Major League Baseball teams, Monday was the first day of games that count in the standings.
While pro ball fans may be seeing their favorite stadiums for the first time in 2015, a few of those stadiums have already seen some game action this year thanks to high school games. AT&T Park in San Francisco, Coors Field in Denver and Safeco Field in Seattle each hosted prep games earlier this season and MaxPreps professional photographers were on hand.
AT&T Park - San FranciscoSt. Ignatius (San Francisco) and
Sacred Heart Cathedral (San Francisco) took to the diamond on March 28, before the Giants could even unfurl their World Series banner.
