Jon Sjogren, Ed.D. was hired in July 2005 and became the fifth head coach in the Tars' illustrious history. 

2023 saw the Tars repeat their success from the previous season, finishing as runner-up at the National Championship in Cary, NC. Rollins was picked to finish 5th in the preseason SSC poll, put together a 34-16 regular season record, and then steamrolled through the playoffs. They defeated #3 Tampa at their place twice in the Regional, swept Barry at Alfond Stadium in the Super Regional, and took down #1 seed Millersville on their way to the championship game in Cary. The team set records for hits, doubles, and home runs in a season. Starting pitcher Edward Berry earned a first-team Academic All-American honor. Sjogren was named the SSC Coach of the Year as well as the ABCA South Region Coach of the Year.  

Under Sjogren's guidance, Rollins made a storybook run to the 2022 Division II National Championship, ultimately finishing third in the country. After finishing 35-15 in the regular season, the Tars earned a #4 seed in the South Region. They swept all three games, leading to a Super Regional matchup with #2 ranked Tampa. Rollins swept both games on the road, earning a berth at the tournament in Cary, NC. After dropping their first game against Southern Arkansas, Rollins won the next three matchups before falling to #4 Point Loma in the semi-finals, giving them a final record of 43-17. Pitcher Jaylyn Whitehead was named a 1st-team All-American, South Region Pitcher of the Year, and SSC Pitcher of the Year. Sjogren was named the ABCA South Region Coach of the Year.   

In 2010, Sjogren led the Tars to a 16-8 Sunshine State Conference record to finish second in the league, the highest finish for Rollins under Sjogren's tenure. Along with the highest conference finish, Rollins' 41-19 overall mark also tied for the second most wins in program history. The 2010 season also marked the first for Sjogren in postseason play while at Rollins.  The Tars went 3-2 with wins over Albany State, Valdosta State, and SSC-foe Florida Southern before falling 7-1 to Southern Arkansas to end their run at the NCAA South Region Tournament title game.

Sjogren has reached four noteworthy milestones at Rollins with career wins No. 400 (March 10, 2007 vs. Eckerd), 500 (April 17, 2010 at Eckerd), 600 (March 14, 2014 vs. University of the Sciences), 700 (May 11, 2018 vs. Florida Tech) and 800 (March 3, 2023 at Lynn).

Prior to taking over the Tars' program, Sjogren served as head coach at Bryant University in Smithfield, Rhode Island for 15 years.  He built the Bulldogs into one of the premier Division II teams in New England. He compiled a career record of 359-305-2 with Bryant, including a victory over Rollins in the opening game of the 2004 NCAA Division II World Series. Sjogren was named the Northeast-10 Coach of the Year four times, and ABCA All-Northeast Region Coach of the Year in 2004. His teams won five Northeast-10 Conference championships and advanced to the NCAA Tournament in 1998, 2002, and 2004. He has coached five players who earned All-America honors. For his success on the playing field at Bryant, Sjogren was inducted into the Northeast-10 Conference Hall of Fame in the fall of 2011.

Sjogren played for Florida Southern in 1985 before transferring to Bryant for the remainder of his career. With the Bulldogs from 1986-88, he established himself as one of the best players in the history of the program, garnering All-Conference honors all three years while posting a career batting average of .370. He led the Bulldogs to a Northeast-10 Conference title and an NCAA Tournament appearance in 1986. In January 2007, he was inducted into the Bryant University Athletic Hall of Fame.

After graduation, Sjogren spent two years as an assistant coach at the University of Rhode Island before returning to take over the Bryant program in 1990. He earned a master's degree from Rhode Island College in 1993 and a doctorate in Education from Boston University in 1998.
