Long lines and metal detectors greeted fans when they tried to enter U.S. Cellular Field to watch the Chicago White Sox take on the Minnesota Twins on opening day.
Major League Baseball has told its 30 teams they must implement security screening for fans by 2015, either with hand-held metal detection or walk-through magnetometers. The White Sox checked fans by hand-held or walkthrough metal detectors depending on where they tried to enter the stadium.
That, and a near-sellout, contributed to lengthy delays trying to see Chris Sale and the White Sox face the Twins on Monday.
