David George Adlesh (July 15, 1943 – February 15, 2016) was a catcher in Major League Baseball from 1963 to 1968. He played his entire Major League career with the Houston Colt 45's/Houston Astros. Adlesh threw and batted right-handed.
Adlesh was signed as an amateur free agent by the Houston Colt 45's in 1963. The Colt 45's thought highly enough of Adlesh's defensive skills that they brought him to the Majors almost at once, with Adlesh appearing in his first Major League game on May 12 of that year. He went 0 for 8 as a hitter in his brief stint and was soon shipped to the minor leagues. Adlesh would split his time between the minors and Houston every year from 1963 to 1966.
When Adlesh's Major League days were over, he had a career batting average of .168, with a slugging percentage of .199, and one career home run. His strikeouts (80) were nearly the double number of his career hits (43).
On June 18, 1967, Adlesh caught the first of Don Wilson's two career no-hitters.
