Over the years the two counties have battled it out in some thrilling matches and many Glamorgan supporters see the games between the two sides as the biggest of the season.
In 2016 Glamorgan were on the verge of qualifying for the knockout stages of the Twenty20 Blast competition but after winning four in a row in the middle of the tournament, the team were on the edge after consecutive defeats.
In a must-win clash, old foes Somerset stood between Glamorgan and a shot at reaching their first Finals Day in 12 years.
In the span of his 17-year career Mark Wallace played in plenty of these rival fixtures, but the 2016 fixture was a particularly special one to the veteran keeper.
"There’s always been a rivalry between Somerset and Glamorgan. Whether it’s here or down at Taunton, there is a tough atmosphere.
"They are enjoyable games to play in and you always want to play in games with a little bit of needle. We’ve had some really good games and close encounters.
"Games like that are trying to perform in the moment. It was a big game, we had to win that to make sure we could qualify for the quarter-finals. We were in good form, there’s always a slightly different feel to these games."
