Rajasthan Royals have announced the signing of four players for the upcoming season of the IPL: Sachin Baby, the captain of Kerala's limited-overs side, wicketkeeper Sanju Samson, Jharkhand seamer Rahul Shukla and Mumbai's left-arm spinner Harmeet Singh.

Baby, who made his first-class debut in 2009, was the fourth-highest run-getter in the recently concluded Vijay Hazare trophy, in which his century in the quarter-finals helped Kerala qualify for the final four. Though his first-class record does not stand out, he has performed well in the 15 List A games he has played in his career so far, averaging 44.72.

Eighteen-year-old Samson was signed by Kolkata Knight Riders last season, but didn't get a game. He was selected in India's Under-19 side for the Asia Cup held in Malaysia in June-July last year, and played three matches, scoring 14 runs. He was dropped for the World Cup in Australia in August. In the Ranji Trophy, he had scored 377 runs in ten innings, at 41.88, and followed it up with a tally of 222 in the Vijay Hazare trophy.

Shukla, who has played for Mumbai Indians before, took six wickets in four matches for Jharkhand in the Vijay Hazare trophy, but hasn't been a regular for the first-class side.

Harmeet, with six wickets at 20.16 in four matches, helped India win the Under-19 World Cup last year. He has so far played only five first-class games - he claimed a seven-for on debut for Mumbai in 2009 - and three List A matches in his career.

Royals will open their campaign against Delhi Daredevils on April 6 at the Feroz Shah Kotla.
