1948 Negro World Series

This was the tenth Negro National League pennant for the Grays, with Harris having led the team to eight of them as manager.

The Black Barons won Game 3 with their young star Mays in hand, who aided the team with speed and the glove, and it was his groundball hit through the pitcher in the ninth inning, that helped drive the runner on second base home to win it for Birmingham.

However, that proved to be the only gasp of magic the team had, as the Grays dominated the Barons in the following two games to win the Series.

Buck Leonard was intentionally walked to load the bases, and Wilmer Fields hit into a fielder's choice that scored the first run.

Eudie Napier doubled, driving in two more, and the Grays' third baseman hit a home run to make it 5–2.

Bill Greason started for the Black Barons, but he was knocked out early and Jehosie Heard, Jimmie Newberry, and Nat Pollard took turns in relief.

In the fifth inning, they added on five, four of which came from a grand slam hit by Luke Easter, his second home run of the Series.

The game went to extra innings, the Grays scored four runs in the top of the 10th on three walks, two singles, and a double.

The Grays sent in Wilmer Fields to pitch the bottom of the 10th, and he shut down the Black Barons to secure the Series win.

Of the six team in the NNL, four teams joined the Negro American League: the Newark Eagles (who moved to Houston), New York Cubans, Philadelphia Stars, and the Baltimore Elite Giants, while the New York Black Yankees did not stay on.

The Grays played in the NAA for one season but found themselves in financial trouble, and they disbanded the following year.

Buck Leonard retired that same year and he was inducted into the National Baseball Hall of Fame and Museum in 1972.

By that time, Mays had become a star for the New York Giants, where he would play for over two decades and eventually become inducted into the National Baseball Hall of Fame and Museum in 1979.
