Report: Woman alleges Bartolo Colon fathered 2 kids with her

— -- New York Mets pitcher Bartolo Colon was in a Manhattan courthouse on Monday to face a woman who alleges in a lawsuit he is the father of her two children, the New York Post reported.

Colon, who has been married to his wife, Rosanna, for 21 years, was sued one year ago by 38-year-old, Alexandra Santos, who alleges the 42-year-old pitcher hasn't paid child support for the two children he fathered with her.

The suit, according to the Post, was filed as "Anonymous v. Anonymous" but because Colon represented himself at one point he is listed as an attorney in the case.

The newspaper reported that documents in the case are sealed and Colon and Santos signed a confidentiality agreement last month. The sides are due to be in court again next month.

Colon has four boys with his wife, Rosanna, but has not publicly acknowledged the 7-year-old daughter and 8-year-old son Santos alleges he fathered.

Rosanna Colon, contacted by the Post, said she was aware of the lawsuit and the claims he has other children but otherwise declined comment.

Bartolo Colon, who is the oldest active player in the majors, is making $7.25 million this season on the one-year contract he signed with the Mets. By the end of this season he will have made more than $101 million in his 19-season career.

"Mr. Colon obviously is a very talented baseball player and he earns a significant income, and we believe that his children should share in the lifestyle they would have enjoyed had their parents remained together," Evan Schein, the attorney who represents Santos, told the Post.

The newspaper reported that Colon's attorney didn't return multiple messages left for him. 

Colon has become a celebrated player in baseball because of his 5-foot-11, 285-pound frame and his comical at-bats and adventures on the bases. He made national headlines on May 7 when he hit his first home run, becoming at 42 years, 349 days the oldest player to hit his first career homer.

Topps sold 8,826 cards with a picture of his home run in a 24-hour period, a record for the company.

Colon, through Wasserman, the agency that represents him, filed for the trademark to "Big Sexy" on April 19, according to a record from the U.S. Patent and Trademark Office. Colon intended to use the trademark on athletic apparel including T-shirts, pants, shorts and hats.

This week, he forged a T-shirt partnership with limited edition T-shirt maker Represent to sell a "Bartbino" shirt, a reference to Babe Ruth's nickname of the "Bambino."

Colon is scheduled to pitch Wednesday night against the Washington Nationals.
