Somerset captain Justin Langer reflected on an "emotional roller-coaster" after his side's five-wicket defeat to Diamond Eagles on Friday.
CJD de Villiers claimed 4-17 as Somerset managed just 132-8 after opting to bat first in Hyderabad.
Morne Van Wyk hit 47 as the Eagles chased down their modest target with eight deliveries to spare, a result that deals a severe blow to the Sabres' hopes of making the semi-finals.
Somerset had started the tournament with a thrilling last-ball victory over the Deccan Chargers in the initial group stage, but defeat to Trinidad and Tobago left their chances of progressing to the second round hinging on T&T defeating the Chargers.
The West Indian side duly obliged, although their victory over the Chargers was another edge-of-the-seat affair.
"The whole tournament has been an emotional roller-coaster for us," Langer said.
"When we beat the Chargers in the first game it was one of the most exciting games I've played in. The crowd was massive, and for our young guys it was huge.
"Then, the flogging against Trinidad was a massive downer, but we were handed another chance when the Chargers lost.
"Today's defeat is really disappointing for us."
Langer, who will retire from cricket at the end of the tournament, believed his team did not play to their full potential and blamed his batsmen for the defeat against the Eagles.
"We played great cricket all throughout this summer, but we haven't played our best cricket here," he added.
"We didn't get off to a good start and we didn't make enough runs and that is the fact of the matter.
"But it's been a great experience for some of our young guys to step up to the next level and from that point of view it is a great thing."
Opener Marcus Trescothick had flown back home due to a recurrence of his stress-related illness and that had left Somerset's misfiring top order looking even weaker, but Langer had only good wishes for the opener.
"He's okay and I think he's feeling better now that he's back in England," he said.
"It's been a tough week or so for him and it was very courageous of him to make it here in the first place. We wish him well of course."
