The pair that is not correctly matched is Option 2: Pamela Jelimo with Weightlifting.

Option 1: Barbora Spotakova and Javelin Throw - This pairing is correct. Barbora Spotakova is a Czech athlete who is widely recognized as one of the most successful javelin throwers in the world. She won gold medals in the javelin throw at the 2008 and 2012 Olympics, becoming the first woman to defend an Olympic javelin title.

Option 3: Sanya Richards and Sprint - This pairing is also correct. Sanya Richards, now known as Sanya Richards-Ross, is an American track and field athlete specializing in sprint events. She is known for her exceptional performances in the 400 meters, and she has won numerous medals in major competitions, including the Olympics and World Championships.

Option 4: Yelena Isinbayeva and Pole Vault - This pairing is correct as well. Yelena Isinbayeva is a Russian former pole vaulter who is widely considered one of the greatest female pole vaulters in history. She has set multiple world records in the event and has won numerous Olympic and World Championship titles.

Option 2: Pamela Jelimo and Weightlifting - This pairing is incorrect. Pamela Jelimo is not known for weightlifting but for her achievements in athletics, particularly in middle-distance running. She is a Kenyan athlete who specializes in the 800 meters. Jelimo burst onto the international scene in 2008 when she won the Olympic gold medal in the 800 meters at the age of 18, becoming the youngest ever Olympic champion in the event.

Therefore, Option 2 is not correctly matched, as Pamela Jelimo is associated with middle-distance running (specifically the 800 meters) rather than weightlifting.
