Despite the team playing down the expected gains from the upgrades,[28] the package nevertheless proved to be disappointing,[29] and McLaren elected to postpone the introduction of some parts amid concerns about their legality.[30] Button and Pérez finished the race in eighth and ninth place respectively, with Button describing the team's performances as being "a bit embarrassing" and admitting that whatever gains the team had made had been marginalised by the development schedules of other teams, who had also used the race to introduce their first major updates for the season.[31] Commentators noted that during the race, Button's fastest lap time was just five hundredths of a second faster than Max Chilton's best lap time set in the Marussia MR02,[32] a car that qualified on the back row of the grid for the race.[33]
