Spring-training baseball scenes were shot at the Philadelphia Phillies' complex in Clearwater, Florida, which is still in use. Rain-delay footage of a grounds crew covering the infield with a tarp was from the 1969 All-Star Game in Washington's RFK Stadium (the game was postponed by rain and played the next day). In the audio over this clip was the voice of long-time Yankees' public-address announcer Bob Sheppard. Baseball-game action clips starting at 01:21 are from MLB films; they are from Yankees and Mets games in 1970 and 1971 – Danny Cater (10), shortstop Gene Michael (17), hitter Jerry Kenney, catcher Thurman Munson (15), and runner Bobby Murcer (1) can be seen.
