Professional career

Early professional years (1998–2005)

Jan Hernych turned professional in 1998 at the age of 18, initially competing on the ITF Futures circuit and ATP Challenger Tour to build his experience and ranking. During these formative years, he secured several victories in Futures events across and , which helped him climb from an initial year-end ranking of No. 528 in 1998 to No. 372 by the end of 1999. In 2002, Hernych began a long-term coaching relationship with Jiří Hřebec, a former Czech professional player, which provided stability and tactical guidance as he transitioned to higher-level competition. That year, he reached the final of the Aptos Challenger and continued to accumulate points through consistent Challenger performances, ending the season ranked No. 214. His progress accelerated in 2004, with a year-end ranking of No. 83, setting the stage for entry into the ATP top 100 the following year. By 2005, Hernych achieved his first top-100 ranking, peaking at No. 60 in July and finishing the year at No. 74 after earning $273,147 in .

Hernych also made his initial Grand Slam main-draw appearances during this period, typically advancing through qualifying before exiting in the first round, though he reached the third round at the US Open in 2005.

Breakthrough and career highs (2006–2009)

In May 2009, he secured his sole ATP doubles title at the BMW Open in , partnering with countryman Ivo Minář to defeat Ashley Fisher and Jordan Kerr 6–4, 6–4 in the final. This period represented his peak performance, with improved consistency on both surfaces contributing to a career singles win-loss record of 79–118 and total prize money earnings of $2,179,237. His enhanced results during these years laid the foundation for a third-round appearance at the 2011 in singles.

Later career and retirement (2010–2018)

Following his career-high ranking of No. 59 in April 2009, Hernych experienced a steady decline in the ATP singles rankings, starting the 2010 season at No. 109 but falling outside the top 100 by August of that year and ending at No. 241. He remained outside the top 100 for the rest of his career, with rankings dropping further to No. 424 by the end of 2016 and reaching a low of No. 1,616 in 2017 before stabilizing in the unranked range by 2018.

Notable Challenger achievements included a title win in in 2010 and in 2012, along with finals appearances such as Wroclaw in 2016.

Hernych demonstrated a solid baseline game, particularly in return play, where he won 50% of points on second serves and converted 41% of break point opportunities. His return games won stood at 23%, suggesting a consistent but not overpowering approach from the back of the court. In doubles, he secured four titles, including one at ATP level, which highlighted his ability to compete effectively at the net alongside partners. Hernych was versatile across surfaces, with his highest career win percentage on grass at 63% (58 wins, 34 losses), though he achieved more volume on clay with a 51% win rate (123–117). His success on clay was evident in multiple Challenger titles, including three in Prague (2004, 2005, 2008) and one in Trnava (2007), all on that surface.

Comparisons to peers

Jan Hernych's baseline-oriented approach aligned with the Czech tennis training system, which prioritizes defensive positioning behind the baseline and hitting high, heavy topspin shots to control rallies. This shared foundational elements with contemporaries like Tomáš Berdych, whose aggressive baseline style relied on powerful flat groundstrokes to dictate play from the back of the court. Both players benefited from the rigorous, technical focus of Czech development programs, emphasizing endurance and shot consistency over flashy net approaches. In contrast to Berdych's elite-level power and consistency—evidenced by his career-high of No. 4 and 13 ATP singles titles—Hernych struggled with sustained performance, peaking at No. 59 in singles with a 79-118 win-loss record and no ATP titles. Similarly, while , another Czech standout, blended baseline solidity with an unconventional all-court game featuring frequent net rushes and early ball-taking, Hernych remained more grounded in steady retrieval rather than versatile attacking. Štěpánek's top-10 singles and doubles prowess (No. 4 career high) highlighted a broader skill set that Hernych did not match in either discipline. Hernych's career leaned more heavily toward doubles, where he achieved a No. 70 ranking and secured one ATP title (2009 Munich with Ivo Minář), differing from the singles dominance pursued by Berdych and Štěpánek. During the mid-2000s ATP era, he embodied underdog status, competing against rising stars like Andy Murray—defeating the 17-year-old Briton 6-3, 4-6, 6-4 in Murray's tour debut at the 2005 Barcelona Open—and Mario Ančić, to whom he lost all five encounters, including a 2007 's-Hertogenbosch final. These matchups underscored Hernych's role as a reliable mid-tier challenger within a golden age of Czech tennis, though without the breakthroughs of his higher-profile peers.

This victory marked Vondroušová's first Grand Slam title and propelled her into the WTA top 10 for the first time, reaching a career-high the following September. The success highlighted Hernych's role in elevating Vondroušová from a mid-tier ranking to major contention, with the duo celebrating through matching strawberry tattoos—a pre-tournament bet fulfillment symbolizing their close team bond.

These results maintained her momentum from the prior year, underscoring Hernych's strategic input in adapting her left-handed, slice-heavy game to varied surfaces despite injury setbacks. By 2025, Vondroušová, under Hernych's continued guidance, secured her third WTA singles title at the Open, overcoming qualifier 7-6(10), 4-6, 6-2 in the final—her first trophy since Wimbledon and a comeback from a No. 164 ranking entering the event. This win boosted her back into the top 100, though subsequent challenges included an early second-round exit at Wimbledon to and a mid-tournament withdrawal from the US Open due to , leaving her at No. 34 by November with an 18-10 record for the year.
