Keith Hayes got his love for writing in the 6th grade where he began writing sci-fi stories for classmates and friends, while continuing to write over the years as a personal hobby.

In 1991 after purchasing WebTV, he caught the Internet bug and began writing on various message boards and newsgroups under the pseudonym Mista Sinista. His posts became popular as he covered movie reviews, the New England Patriots, WCW and WWE (formerly WWF) wrestling. Just do a Google search for Mista Sinista or Sinista1 under groups, and you'll discover enough material to read for months.

As his debating talents developed online, he became vocal in his local newspaper, the Enterprise. He began submitting Letters to the Editor, and most of his pieces were printed on a regular basis. He also had similar success with his letters to the early years of Patriots Football Weekly. After generating some buzz and catching the eyes of readers, Keith was contacted to write for wrestling web site Wrestlenutz.com. He was then later contacted to write for a New England Patriots fan website PatriotsFootball.com, which is now known as PatsFans.com.

When covering the Pats, Keith kept his Mista Sinista attitude and reviewed the games with his "tell it like it is" style. The Patriots experience soon took off, and allowed him to meet various players, travel to a Pro Bowl in Hawaii, a Super Bowl in New Orleans, several away games in the Meadowlands, and some great games in Foxboro, where he has been a season ticket holder since 1990.

Today, he covers the New England Patriots for eSports and as a 12th Man correspondent for PatsFans.com. You can read his political and local debates on his hometown site Brockton Forums. But for a real treat, you can also see the twisted side on his moniker web site Sinista1.com, where he has some great spoofs like "Barbie and Ken's True Hollywood Story," and "Celebrity Survivor."

Most recently, Keith has become a co-host on two hit radio shows at WXBR 1460 AM in Brockton (formerly WBET). On Fridays, Keith can be heard during the "On the Mark PI Show," with his host Private Investigator Mark Chauppetta, who has his own reality television show in negotiations, and a role in the upcoming horror film Frightworld where he plays an FBI Agent hunting a serial killer who has killed his wife.

Keith is now following in his host’s footsteps after scoring a part in Walt Disney's upcoming movie "The Game Plan," starring Dwayne "The Rock" Johnson. In the movie, Keith plays a football player on QB Joe Kingman’s (Dwayne's character) Boston Rebels rival team the New York Dukes. Also joining Keith on the show is defense attorney Ken Diesenhof, and Brockton Police Officer Frank "Czman".

On Saturdays, Keith can be heard during "Krashing Into the Bigfield/The Lock Up" from noon to 4 p.m. talking sports with Enterprise writer Kevin Tocci, and aspiring actor Tom Mariano, cousin to "Boston Rob" of "Survivor/Amazing Race" fame. The show also features guests Matt Futrell, Peter Czymbor, Dennis Harris, and is produced by former Indie wrestler Mike Pavia. The South Shore Sports Show is growing, as the first two hours cover sports (professional and local), while the second two hours cover the best talk in professional and Indie wrestling.
