A right-handed pitcher, he appeared in 66 games in Major League Baseball over four seasons between 1952 and 1958 for the Brooklyn / Los Angeles Dodgers and Philadelphia Phillies.

[1] Negray began his 15-year pro career in 1949 in the Brooklyn farm system, winning 21 games in the Class D Georgia–Florida League.

His first taste of MLB service came at the tail end of the 1952 campaign, when the pennant-bound Dodgers recalled him from the Triple-A St. Paul Saints.

[3] In his third start on June 29, Negray notched his first complete game in MLB, defeating the Pittsburgh Pirates 6–3 at Connie Mack Stadium, giving up only two earned runs.

During spring training in 1957, he was traded back to the Dodgers in a six-player transaction that brought shortstop Humberto "Chico" Fernández to Philadelphia.

On March 8, 1958, he was the starting pitcher in the franchise's first spring training game as representatives of Los Angeles, a 7–4 loss to the Phillies at Miami Stadium.

He allowed 170 hits and 57 bases on balls in 1622⁄3 innings pitched, posting two complete games, three saves, no shutouts, and 81 strikeouts.
