Robert Alexis Machado [ma-cha'-do] (born June 3, 1973) is a former Venezuelan catcher in Major League Baseball who played from 1998 through 2004 for the Chicago White Sox, Montreal Expos, Seattle Mariners, Chicago Cubs, Milwaukee Brewers and Baltimore Orioles.

Machado was a solid defensive catcher with a strong arm, but his little offensive value limited his effectiveness as an everyday player.

On June 9, 2002, the Cubs traded Machado to the Brewers for previously heralded prospect Jackson Melián.

[1] Machado also played in all or part of 13 Minor League seasons spanning 1991–2004, posting a .273 average with 70 homers and 392 RBI in 862 games.

In February 2009, Machado received a 15-game suspension for violating MLB-Minor League drug treatment and prevention program while trying to return to organized baseball.
