Simon Diamond

On June 19, 2017, Kenney left Impact Wrestling alongside Shane Helms and Al Snow.

At May 8, 2012, Kenny substituted Taz as Color Commentator at TNA Xplosion, joining Jeremy Borash.

Kenney returned to television on the July 15, 2010, edition of Impact!, aligning himself with fellow ECW alumni Tommy Dreamer, Raven, Stevie Richards, Rhino, Brother Devon, Al Snow and Mick Foley in their invasion of TNA. The following week, TNA president Dixie Carter agreed to give the ECW alumni their own reunion pay–per–view event, Hardcore Justice: The Last Stand, as a celebration of hardcore wrestling and a final farewell to the company. At the event Kenney returned to his Simon Diamond persona and teamed with Johnny Swinger and Kid Kash in a six-man tag team match, where they were defeated by Little Guido, Tony Luke and Tracy Smothers of The Full Blooded Italians.

On September 18, 2009, TNA Wrestling announced that Kenney had been rehired as a road agent to replace the fired Jim Cornette and B.G. James.

In 2009, Kenney filed a sexual abuse lawsuit against a former priest at Salesianum School.

On November 3, 2008, Kenney was released from his contract with TNA, with them citing budgetary cuts as the reason.

Kenney's prior baseball career would later be used as an angle when he would visit the training camp of the 2005 world champions, the Chicago White Sox.

Kenney returned to TNA on June 19, 2005 at Slammiversary as the heel Simon Diamond once more. At Slammiversary, Kenney teamed with Trytan (who he referred to as his "insurance policy") to defeat Sonny Siaki and Apolo. The next month, Trytan was gone, and at No Surrender 2005 Diamond presented David Young, suggesting that, in Young, he had found "a diamond in the rough". "Primetime" Elix Skipper joined with Diamond and Young at Sacrifice on August 14.

In September 2005, Kenney spent two weeks in India, where he and fellow TNA employees Sonjay Dutt and Shark Boy visited several cities, promoting the debut of Impact! on ESPN Star Sports. On September 28 in Bhopal, a riot broke out when 1,000 fans were excluded from an event after attendance exceeded expectations. None of the three TNA wrestlers were injured.

Kenney returned to America in October 2005, and on December 8 started an angle with Chicago White Sox catcher A. J. Pierzynski. At Turning Point the Diamonds in the Rough (Diamond, Young and Skipper) were defeated in a six-man tag team match by Chris Sabin, Sonjay Dutt and Dale Torborg, who had Pierzynski in their corner. Pierzynszki returned to TNA in March 2006 and was once again confronted by Diamond, who ended up getting hit with a chair by the White Sox catcher. Shortly thereafter Kenney became a road agent for TNA.

Kenney and Swinger separated in 2004 and engaged in a feud, which saw Kenney turn face and embrace his Irish heritage, wrestling as "Irish" Pat Kenney. After being briefly renamed The Empire Saint, Kenney was not booked by TNA for several months, during which time he spent three weeks competing in Japan with the Zero-1 promotion.

On July 9, 2003, Kenney and Swinger appeared on a Total Nonstop Action Wrestling (TNA) pay-per-view, beginning a feud with America's Most Wanted (Chris Harris and James Storm). Enlisting the services of manager Glenn Gilbertti, the duo won the NWA World Tag Team Championships on August 27, 2003, and held the titles until November 19, when the titles were held up following a controversial ending to a match with the 3 Live Kru.

The impending bankruptcy of ECW in 2001 forced Diamond to seek employment elsewhere, and he began negotiations with World Championship Wrestling (WCW) employee John Laurinaitis, which fell through when WCW was purchased by the World Wrestling Federation in March 2001.

Diamond and Swinger joined forces with C.W. Anderson in mid-2000, and began to ascend the ranks of the promotion.

Diamond appeared as a playable character in the 2000 video game ECW Hardcore Revolution.

In May 1998, Kenney was hired by Extreme Championship Wrestling (ECW), and wrestled his first match against Nova in York, Pennsylvania. In August 1998, he changed his name to "Simon Diamond", taking the name "Simon" from the real surname of his mentor, Dean Malenko. Kenney was paired with Swinger in May 2000 during an ECW World Tag Team Championship tournament and the two later formed a tag team which would endure for five more years.

Kenney began dating Dawn Marie in October 1998. Before dating, the two had been good friends for almost two years. They had planned to be married by the end of 2000 or into 2001. They did not wed, but stayed engaged for several years afterwards. After seven years together, their relationship began to come to an end. Kenney and Candice Kenney have a child born in 2010.

In 1991, while working as a marketing executive for PepsiCo, Kenney was introduced to wrestling trainer Jim Kettner. Kenney decided to become a professional wrestler, and was trained by Kettner in Salem, New Jersey. Once his training was complete, he worked for Kettner's East Coast Wrestling Association as "Lance Diamond", teaming with Steve Corino.

Patrick Kenney was an avid baseball player as a teenager, and was approached by the San Diego Padres to play Major League Baseball as a catcher in 1986. Kenney decided not to sign the contract he was offered, opting to pursue a college education first. Kenney took a job at the Out Of Bounds sports bar as a bartender and attended Virginia Commonwealth University on a baseball scholarship, earning a bachelor's degree in English. He originally planned to play baseball professionally after graduating, but was forced to reconsider after suffering a severe shoulder injury.

Patrick Kenney (born May 26, 1968) is an American retired professional wrestler and baseball player, better known by his ring name, Simon Diamond. He most recently worked for professional wrestling promotion Impact Wrestling as a producer. Diamond is best known for his appearances with Extreme Championship Wrestling from 1998 to 2001.
