In 2011, with five newcomers in the starting lineups, Gajdzik led Purdue to 13 wins, its highest single-season win total since 2003. Two Boilermakers nabbed postseason conference honors as freshmen Szymon Tatarczyk and Mark Kovacs were named Second Team All-Big Ten. Purdue was in the national rankings for 11 weeks in Gajdzik's second season at the helm and also finished second at the San Diego Invitational.
In 2009-10, Purdue had 11 wins under Gajdzik's direction, the school's highest total since the 2003 season. Eight Purdue athletes earned career-high win totals in their first season under Gajdzik's direction. Gajdzik and assistant coach Brandon Lenfert welcome their first recruiting class and the 24th-ranked group according to tennisrecruiting.net in the fall of 2010.
Gajdzik came to Purdue after spending the 2009-2010 season as head coach at Northern Illinois. He led the Huskies to a 9-10 overall record, including a 3-2 MAC mark that tied for second in the conference, in his first season in charge. Northern Illinois' second-place MAC showing was the highest for the school since 1997 and included the program's first victory over Ball State since 1974.
The Huskies managed postseason acclaim as well in Gajdzik's first season. Pawel Poziomski was named MAC Newcomer of the Year and All-MAC second team. Fellow freshman Jurica Grubisic was a first-team All-MAC selection, and junior Javier Bernabe was named to the second team. Gajdzik's 2009 recruiting class was named the No. 1 mid-major class in the country by TennisRecruiting.net.
Before taking over at Northern Illinois in 2009, Gajdzik spent six seasons on the coaching staff at Baylor. The Bears won the 2004 national championship and the 2005 national indoor team title before earning a national runner-up finish in 2005. Baylor also advanced to the national semifinal in 2006 and 2007 and the national quarterfinal in 2003 and 2008. The Bears brought six consecutive Big 12 championships and five Big 12 tournament titles back to Waco in that time, as well.
Gajdzik directed 2004 NCAA singles champion Benjamin Becker and 2005 NCAA singles champion Benedikt Dorsch, who were two of the four All-Americans to play at Baylor while Gajdzik was on staff. In addition to his coaching duties at Baylor, Gajdzik founded the PG Tennis Academy in 2005.
During his playing days at Baylor, Gajdzik won the 1998 Big 12 singles and doubles titles and was named the conference's Newcomer of the Year while leading the team to its first NCAA tournament appearance. In his first season of collegiate tennis, he was ranked as high as 17th in singles and was in the top 20 in the doubles rankings with two different partners. His 8-0 conference mark that season still stands as the best single-season mark in school history. The following year, Baylor put together a 25-4 record and advanced to the national quarterfinals. In 2000, Gajdzik won another Big 12 doubles crown while leading the Bears to the first men's team conference title in school history and a Round of 16 berth in the NCAA tournament.
Prior to coming to the United States, Gajdzik was a member of Poland's national team from 1989 to 1997. He was an ATP ranked professional player in singles and doubles while playing for the Polish Junior National Team. Gajdzik also won a national championship and was ranked in the top five throughout his junior career.
