Thomas Ross House (born April 29, 1947) is an American former left-handed relief pitcher in Major League Baseball, as well as an author and a pitching coach.

He had passed up an earlier chance to turn pro two years before, when the Chicago Cubs used the 201st overall pick to take him in the 11th round of the June draft's main phase.

[3][4] Early in his career, he employed what were thought of as unusual methods at the time, but have since been adopted by the baseball community at large such as having pitchers under his tutelage throw a football.

[6]House has also worked as a coach for the Houston Astros, San Diego Padres, Chunichi Dragons, and Chiba Lotte Marines.

At the end of that time he had raised the velocity of both prospects' fastballs to major league levels, and the two signed professional baseball contracts with the Pittsburgh Pirates' organization.

Recently, House has worked with several NFL quarterbacks, including, Dak Prescott, Drew Brees, Tom Brady,[9] Alex Smith,[10] Carson Palmer, Cody Kessler, Matt Cassel, Jared Goff, Marcus Mariota, Andrew Luck, Jimmy Garoppolo, Carson Wentz, Terrelle Pryor, Tim Tebow, Andy Dalton,[11] Blake Bortles,[12] Matt Ryan,[13][14] and Mac Jones.

He has developed a model that is focused on quantifying the movement in each athlete's motion, then using drills and exercises to maximize accuracy and velocity and minimize strain on player's bodies.

He viewed the experience as a failure since the extra muscle did not enhance his substandard 82-MPH fastball, while the drugs contributed to knee problems, eventually necessitating a total of seven operations.

Aaron hit the record-setting 715th home run in the fourth inning of a game against the Los Angeles Dodgers, on April 8, 1974, against pitcher Al Downing.

The game stopped to celebrate the achievement, and after sprinting to the infield, House presented the ball to Aaron at home plate.
