Gayle has returned to the ODI squad after a hiatus. He was last seen playing for West Indies in the World Cup last year and has been named for the ODI series against England that is due to start later this month.
Barath and Kieran Powell, who have been struggling to perform against England in the on-going Test series, having lost the series 0-2, the duo have been left out of the one day squad.
But the opening batsman Barath sportingly added Gayle's return would boost the confidence in the playing XI and everyone have high regard for the Jamaican.
"We always welcome players into the set-up. He's been in the set-up for years and everyone has respect for Chris.
"It's great to have him back and he'll lend experience to our players," added the 22-year-old Trinidad batsman, who in 14 one-dayers has scored one hundred.
"We're looking forward to having him in the set-up and everyone will learn from him.
"Having Chris in our team (makes it) a really solid team. The depth in our batting - with Kieron Pollard, Darren Sammy, the Bravos (Dwayne and Darren), Marlon Samuels, Andre Russell - once we get going in the powerplay it would be difficult to say how could we not chase a big score or set one.
"So once we get it right, we have a good ODI team and we're working on getting there in Tests, also."
West Indies are scheduled to play three one day internationals followed by a one-off T20 starting from June 16, 2012.
