Jennie Finch married Minnesota Twins pitcher Casey Daigle on January 15, 2005, at the Crystal Cathedral in Garden Grove, California. Finch and Daigle welcomed a son Ace on May 4, 2006. After an induction because Finch was overdue, Ace Shane Daigle was born in Tucson, Arizona.
Finch defeated Anna Kournikova in an ESPN online poll as the most attractive female athlete. Like Kournikova, Finch has modeled swimwear for the Sports Illustrated Swimsuit Edition in 2005-06.
Finch has appeared on various talk shows promoting softball and the US Olympic Team, and also hosts a segment on the TV program This Week in Baseball. Her "This Week in Baseball" segment often features her pitching to major-league baseball players, using a softball and pitching from the same distance she would in a softball game. Finch usually strikes out the baseball players by using her 71 mph riseball that is equivalent to a fastball of nearly 100 mph in baseball, where the pitcher's rubber is 17.5 feet farther away than in softball.
She was offered a lucrative contract to appear nude for Playboy magazine, but commented to the press on August 14, 2004, that the offer was not going to tempt her. She said that she would "rather be a role model for young girls." She also said that "muscles on women are beautiful, but my personal decision is to stay away from those things; to stay away from that." She once appeared on the cover of Sports Illustrated wearing a tank top and a mini skirt.
Finch currently works for ESPN. She also pitches for the Chicago Bandits of the National Pro Fastpitch Softball League. She was named the NPF's Co-Pitcher of the Year in 2005, sharing the award with teammate Lauren Bay.
She was featured as a contestant on the new celebrity edition of The Apprentice. She was fired by Donald Trump on January 24, 2008.
Her family has also invented machines and for the common softball player to learn techniques such as pitching, and how to become better at them.
Finch recently appeared on an episode of The Real Housewives of Orange County, which aired December 18, 2007.
