Arthur “Ted” Stenberg IV enters into his 23th year coaching baseball, and 3rd as the New Market Rebels Head Baseball Coach.  He capped his seventh year of college summer league coaching by leading the Niagara Power of the New York Collegiate League to their first-ever league championship in 2019, finishing at 34-12-1.

 The quality of coaches I had with me, after a six or seven week search, shared my vision for a summer season, the message that we gave to the players stayed consistent throughout the summer – come to the ballpark with energy every day and be coachable, was the key to winning that championship,” Stenberg said in a phone interview.

Stenberg started his college baseball career at Florida Southern from 1995-1997 and continued it at the University of Tampa from 1998-2000 where he earned a degree in Exercise Science and Sports Management.  He played a variety of positions including First base, Third base and Pitcher.  After his college career, he signed a professional contract with the Pensacola Pelicans in 2003 as a pitcher, where he played until an injury ended his career.

 Among the players that Stenberg has coached, thirteen were selected in the Major League Baseball draft, 2010-2016, and five were free agent signees. Three of those players were on 2022 Major League rosters: right-hand pitchers Art Warren with the Cincinnati Reds, Trevor Richards with the Toronto Blue Jays, Matt Peacock with the Arizona Diamondbacks, also left-hand pitcher Travis Bergen, who is in the minors with the San Diego Padres.

During the summer of 2020, Stenberg obtained the Florida Baseball Armory SAVAGE pitching certification, Driveline Foundations of Pitching and Basics of Pitch Design certifications, as well as Rapsodo Pitching Certification.

Stenberg has worked with some great coaches, as well as coached and mentored some good players. He attributes his success to learning from each of them.
