Who won the Men's Singles title at the 2016 US Open Tennis Championships?

Introduction / Context:
The US Open is one of the four Grand Slam tournaments in professional tennis, and its champions are frequently asked about in sports general knowledge questions. The 2016 Men's Singles final featured some of the biggest names in modern tennis. This question specifically focuses on identifying who emerged as the winner that year, a key fact about recent Grand Slam history.

Given Data / Assumptions:

• The event is the US Open Tennis Championships.
• The year is 2016.
• The category is Men's Singles.
• Options include Novak Djokovic, Rafael Nadal, Stan Wawrinka and Andy Murray.

Concept / Approach:
The approach is to recall the Grand Slam winners for that season. In 2016, Stan Wawrinka won the Men's Singles title at the US Open by defeating Novak Djokovic in the final. Novak Djokovic, Rafael Nadal and Andy Murray have each won multiple Grand Slams, which makes them plausible alternatives, but they did not capture this specific title in that particular year. Remembering Wawrinka's run as a powerful baseline player with a heavy backhand helps to pick the correct answer.

Step-by-Step Solution:
Step 1: Recall that the 2016 US Open Men's Singles final was contested between Stan Wawrinka and Novak Djokovic.Step 2: Remember that Stan Wawrinka defeated Djokovic in that final to claim his third Grand Slam title.Step 3: Check the options: Djokovic, Nadal, Wawrinka and Murray are all elite players, but only one of them actually won the 2016 US Open.Step 4: Nadal and Murray did not win this event that year and were eliminated earlier.Step 5: Therefore, the correct answer from the given options is Stan Wawrinka.

Verification / Alternative check:
You can verify by recalling the pattern of Wawrinka's Grand Slam wins: he captured the Australian Open in 2014, the French Open in 2015, and the US Open in 2016. This chronological sequence is often highlighted in tennis summaries describing his career. Novak Djokovic has more US Open titles overall, but not specifically the 2016 edition. Nadal and Murray have their own peak years associated with other tournaments. This context confirms that Wawrinka is the rightful 2016 US Open Men's Singles champion.

Why Other Options Are Wrong:
Novak Djokovic is a strong contender and was the runner up in the 2016 US Open final, but he did not win the title. Rafael Nadal has won the US Open several times, yet his victories came in different years. Andy Murray also holds a US Open crown, but his title was from 2012, not 2016. Since the question is tied to a specific year, these otherwise great players are incorrect choices here.

Common Pitfalls:
Many learners see Novak Djokovic's name and instinctively select it because of his overall dominance in the mid 2010s. Others may confuse the winners of different Grand Slams in the same year. To avoid these mistakes, it is helpful to memorise a brief list of champions by year for each Grand Slam, and to link 2016 US Open Men's Singles firmly with Stan Wawrinka in your revision notes.

Final Answer:
The Men's Singles title at the 2016 US Open was won by Stan Wawrinka.
