Robert Thomas Aspromonte (born June 19, 1938) is an American former professional baseball player and business entrepreneur.

[3] Aspromonte was born in Brooklyn, New York where he graduated from Lafayette High School and made his pro debut in the Class A Southern League.

On September 19, during a 17–2 triumph over the St. Louis Cardinals at Ebbets Field, Aspromonte made his MLB debut at age 18, striking out as a pinch hitter for Sandy Amoros in the eighth inning.

[4] It was Aspromonte's lone appearance in a Brooklyn uniform: he spent the next three seasons in minor league baseball before making the 1960 Los Angeles Dodgers roster out of spring training.

On May 5, 1960, his four hits in five at bats, including his first major league home run (off Lew Burdette), led the Dodgers to a come-from-behind win over their rival, the Milwaukee Braves.

On April 10, 1962, Aspromonte, playing third base and inserted into the leadoff position, became the first batter in Houston's MLB history.

He singled to left field off Don Cardwell of the Chicago Cubs for the club's first hit, then scored its first-ever MLB run when the next batter, Al Spangler, tripled.

Aspromonte reached the postseason for the only time in his career with the 1969 National League Championship Series, where he went 0-for-3 as the Braves lost to the New York Mets in a three-game sweep.

In his final game, the last Brooklyn Dodger to play in the major leagues went hitless in three at bats, with an RBI, against the Cardinals' Steve Carlton at Shea Stadium.

On January 26, 2019, it was announced that Aspromonte would be an inaugural member of the Houston Astros Hall of Fame and was inducted on August 3, 2019.
