Matt Sinatro

After drawing his release from the Mariners in October 1992, Sinatro was Seattle's MLB advance scout in 1993–94 before joining the big-league coaching staff of manager Lou Piniella. He would spend his entire coaching career working for Piniella as bullpen coach, first-base coach or special assistant with the Mariners, Tampa Bay Devil Rays and Chicago Cubs. In 2012, he served the Houston Astros as catching coordinator and advance scout.

But offensive struggles (he batted only .245 during a 1,044-game minor league career) hindered Sinatro's development. He was never a regular player in the big leagues, nor did he play in more than 37 games in any MLB season. His 48 career big-league hits included six doubles, one triple, and one home run, a two-run blow off Pete Falcone of the New York Mets on August 27, 1982. The homer contributed to a 9–8 Atlanta victory in a year when the Braves prevailed over the Los Angeles Dodgers to win the National League West Division championship by a single game.

Sinatro was listed as 5 feet 9 inches (1.75 m) tall and 174 pounds (79 kg); he threw and batted right-handed. After graduating from Conard High School in West Hartford, he was selected by the Braves in the second round of the 1978 Major League Baseball Draft. He was the 27th player chosen overall, 21 slots ahead of eventual Baseball Hall of Famer Cal Ripken, Jr.
