Paul Anthony Lo Duca (born April 12, 1972) is an American former professional baseball player and television personality.

He played in Major League Baseball as a catcher for the Los Angeles Dodgers (1998–2004), Florida Marlins (2004–2005, 2008), New York Mets (2006–2007), and Washington Nationals (2008).

Lo Duca walked on to the baseball team at Glendale Community College in Arizona after he was not recruited or drafted out of high school.

He was named ASU "On Deck Circle" Most Valuable Player; other winners include Dustin Pedroia, Willie Bloomquist, Ike Davis, and Barry Bonds.

[4] In 2003, Lo Duca's 25-game hitting streak was the second longest in Dodgers history, and defensively, he ranked first in the National League in throwing out baserunners.

Later, Lo Duca was traded to the Mets for two minor league prospects: pitcher Gaby Hernandez and outfielder Dante Brinkley.

Lo Duca was a member of the 2006 All-Star Team, and the Mets finished that year with a 97-65 record and made the postseason (his first playoff experience).

On October 22, 2019, MLB umpire Joe West filed a defamation lawsuit in New York against Lo Duca and Action Network over comments Lo Duca made on a podcast in April 2019, recalling his Mets teammate Billy Wagner telling him, "Joe loves antique cars so every time he comes into town I lend him my ’57 Chevy so he can drive it around so then he opens up the strike zone for me.

The report also claims that Lo Duca introduced several other baseball players to Radomski, including Adam Riggs, Kevin Brown, Éric Gagné, and Matt Herges.

On January 9, 2013, in response to the Baseball Hall of Fame announcement in which no players were elected, Lo Duca acknowledged his steroids use, tweeting "I took PEDs and I'm not proud of it...but people who think you can take a shot or a pill and play like the legends on that ballot need help."

On August 7, 2006, the New York media leaked a story about his divorce suit with his wife, Sonia (Flores) Lo Duca, a former Playboy model.

Lo Duca had been "one of the most helpful and available players in the Mets clubhouse", and afterward resumed giving interviews, as long as they pertained to baseball.
