1954–1957: early Test career

Sobers had progressed quickly and made his Test debut in March 1954, aged 17, against England at Sabina Park in Kingston, Jamaica, for the fifth and final Test, after Alf Valentine had fallen ill. Sobers was selected as a bowler, despite only mediocre performances against England for Barbados. He made a good impression by taking 4/75 in England's first innings, including a wicket in his opening over. Sobers also scored 14 not out and 26 batting at number nine; however, England won the match by nine wickets.

Australia toured the West Indies in 1954–55, and their all-rounder Keith Miller thought that Sobers would become a better batsman than bowler despite batting in the lower-order. Sobers was not selected for the First Test, which the West Indies lost by nine wickets. However, he regained his place for the Second Test in Port of Spain, Trinidad and Tobago. The match was a high-scoring draw, with Sobers scoring 47 and eight not out. He was barely used with the ball, bowling three overs for ten runs, as Australia amassed a first-innings total of over 600. Sobers was given a further opportunity in the next Test in Georgetown, Guyana (British Guiana at the time) in South America. Despite scoring only 12 and 11 with the bat, he took three wickets in the Australians' first innings. Nevertheless, Australia won by eight wickets. West Indian captain and opening batsman Jeff Stollmeyer twisted his ankle after treading on a ball ahead of the Fourth Test in Barbados, "triggering huge debate about who should open." Eventually, Sobers was chosen to open the innings after Australia had amassed another total of over 600. Sobers had a suspicion he might be asked to do the job. "I couldn't see them sending in anyone else—I was a bowler with a little ability as a batsman and they wanted someone to help see off the shine and protect the three W's." Sobers struck his first three deliveries for boundaries, all from the bowling of Miller. In the fast bowler's second over, Sobers hit him for another three fours. He was eventually dismissed for 43 out of a first-wicket partnership of 52 with John Holt. The match was drawn, and Sobers took one wicket in the Australians' only innings, before scoring 11 in the West Indies second innings. The home team were again defeated in the fifth and final Test in Jamaica. Sobers performed with the bat, however, scoring 35 not out and 64.

Sobers went on his first overseas tour in the early months of 1956 when, aged 19, he was part of the West Indian tour of New Zealand. The series was not successful personally for Sobers, who struggled on the foreign batting wickets. West Indies pitches had little or no grass, while in New Zealand the pitches were green. "I took one look and asked myself how I could possibly bat on that? How could I make runs? I was out before I even walked to the crease," Sobers later wrote. Playing in all four Tests, he totalled 81 runs and two wickets. As a batsman, Sobers needed time to develop at Test level and, in nine Tests as a teenager, he scored only one half century, and averaged 29.33 with the bat.

Sobers was sent home from New Zealand early to play an unofficial Test match against an England team that included feared fast-bowler Frank Tyson. After struggling to cope with Tyson's pace, Sobers managed to score a half-century, raising hope that he would be selected for the upcoming tour to England, something he considered unlikely after his lack of form. In the first trial match to help select the squad for the upcoming tour, Sobers scored a century in Trinidad. The matches also saw Sobers get his first look at West Indian cricket politics. Wes Hall and Frank Mason were competing for a single place in the touring party, and Sobers and Everton Weekes decided they "would take on Mason and knock him out of the firing line to try and get our fellow Bajan (countryman) Wes in the team." The pair attacked Mason, while they defended Hall in a tactic that paid off with Hall selected, despite Sobers believing Mason was the better bowler at the time.

Sobers toured England for their summer in 1957. He played his first match against the Jim Swanton XI in April, and was surprised about how cold the conditions were, often causing him to wear two or three jumpers. His performances with the bat throughout the five Test series were classed as mediocre, scoring 320 runs at 32, with three half centuries. On the bowling front, Sobers struggled, taking five wickets at 71. It was in the final Test at The Oval that Sobers gained the attention of critics with defiant batting amid a disappointing team performance. The condition of the pitch was subject to criticism and described by Wisden Cricketers' Almanack as "a strange sight". After England had scored 412, the West Indies were easily dismissed for 89 and 86 by the Surrey spinners Jim Laker and Tony Lock, who were playing on their home ground. Batting at number 3, Sobers made 39 and 42, while none of his colleagues passed 30 in either innings. In its summary of the tour, Wisden said: "(of the newcomers) Collie Smith, Sobers, Rohan Kanhai and Roy Gilchrist were particularly impressive"; adding that "to Sobers, a tall left-handed all-rounder, fell the distinction of hitting the highest score of the tour: 219 not out against Nottinghamshire at Trent Bridge. Sobers undoubtedly was a very fine stroke-player who should go far".
