Jesús Antonio Guzmán Álvarez (born June 14, 1984) is a Venezuelan former professional baseball first baseman and left fielder.

Guzmán came to the United States in 2004 and played with the Seattle High-A and Double-A affiliates through 2007 when he was granted free agency.

The San Francisco Giants signed Guzmán as a minor league free agent and invited him to spring training in 2009.

Guzmán spent all of 2010 with the Giants' Triple-A club, where he posted nearly identical numbers to 2009, a .321 batting average and .886 OPS in 125 games, while playing mostly in left field and at third base.

[3][4] Padres general manager Jed Hoyer projected Guzmán as a second option at first base (behind Yonder Alonso) in 2012, otherwise he was a possibility in left field.

He made 25 starts in left field, allowing Carlos Quentin to rest his knees early and late in the season.

He also made 33 starts at first base, many in late June and early July when Yonder Alonso was out with a hand injury.

On October 26, 2014, it was announced that he had signed a one-year, $1 million contract with the Hiroshima Toyo Carp of Nippon Professional Baseball.
