The New York Times of April 14, 1914 reported on the New York Giants finishing up their exhibition series with the Baltimore Orioles in Baltimore on April 13 with a 3-2 win. With 25,000 attending the start of the season for Baltimore’s Federal League team, only 1,000 saw the exhibition. The Giants were ending their spring training; their season would start in Philadelphia on the 14th. The Times noted that “‘Babe’ Ruth, a youngster, opposed the Giants, who made nine hits off him. Four double plays, all started by Claude Derrick (the shortstop), who handled twelve out of the thirteen chances, kept the Giants from scoring more runs.”
Ruth went 0-4 at the plate, batting ninth. He allowed two walks, struck out seven, and hit two batters. He pitched a complete game that took two hours to play. It was his first professional season; he had turned 19 in early February. His official debut with the Orioles came on April 22, 1914. This game against the Giants was about his third ever against major-league competition: read this article for details on the earlier games.
