His name is Carlos Gonzalez, and he has been a menace to National League pitching this season.
Gonzalez, 24, is a tall, lean lefty with a sweet swing.
Originally from Venezuela, Gonzalez is in his second full year with the Colorado Rockies. He came to the Rockies in the Winter of 2008 when the Rockies dealt Matt Holliday to the Oakland A's.
Gonzalez has made A's general manager Bill Beane regret this trade.
In 2009, Gonzalez spent the first two months of the season dominating the Pacific Coast League for the Rockies Triple-A affiliate in Colorado Springs.
On May 29, the Rockies fired manager Clint Hurdle and replaced him with Jim Tracy. A week later, Gonzalez got the call to the majors.
