[5] Twenty days later, over the same course and distance, the filly started 8/11 favourite for the Group 3 Fillies'Sprint Stakes and recorded another easy win, beating Actress by five lengths.

[6] A month later she was sent to England and started favourite in a twenty-runner field for the Albany Stakes but despite finishing strongly he failed to overhaul the French filly Different League and was beaten a neck into second place.

At Leopardstown Racecourse on 14 April Alpha Centauri began her second season 1,000 Guineas Trial Stakes and finished tenth of the thirteen runners behind Who's Steph in a race run on heavy ground.

Alpha Centauri was settled in mid-division as Could It Be Love, a 33/1 outsider who was presumed to be running as a pacemaker for the Aidan O'Brien stable's more fancied runners set off in front and opened up a long lead.

Approaching the final furlong Could It Be Love was still in front and looked to be on the verge of a huge upset victory but Alpha Centauri produced a strong late run, gained the advantage in the last hundred yards and won by one and three quarter lengths.

Starting at odds of 4/9 she took the lead after the first quarter mile and was never in danger of defeat, drawing away in the closing stages to win "easily" by four and a half lengths from Altyn Orda.

In response to the performance the official Irish Handicapper gave her a rating of 124, making her the highest-rated Irish-trained three-year-old filly since Ridgewood Pearl in 1995.

After turning into the straight in third place she made good progress to move into second but was unable to overhaul the British-trained filly Laurens and was beaten three quarters of a length.
