Nobuharu Matsushita for ART Grand Prix won the following day's 30-lap sprint race from pole position with Carlin's Marvin Kirchhöfer and Markelov's teammate Raffaele Marciello second and third.

Sergey Sirotkin won the pole position for the feature race by posting the fastest lap in qualifying but a slow start off the grid allowed Nato into the lead.

Nato pulled away from the rest of the field and led for the majority of the race until a virtual safety car caught him out in the event's closing laps.

Markelov was the main beneficiary of this and he made his mandatory pit stop to change tyres on the penultimate lap and held off Nato to take his maiden GP2 Series win.

In the Teams' Championship, Russian Time moved from fourth to first and Racing Engineering were eleven points behind but they retained second place.

The leaders of the Teams' Championship enterin the event DAMS dropped to third while Prema Racing fell to fourth with eight rounds left in the season.

[2] The drag reduction system (DRS) had one activation zone for the race: on the start/finish straight linking Anthony Noghes and Sainte Devote turns.

Daniël de Jong (MP Motorsport) oversteered into the Sainte Devote barrier and Sean Gelael (Campos Racing) ended the session early when he stalled his car and triggered a traffic holdup.

Lynn, Antonio Giovinazzi (Prema Racing), Marciello, Latifi and Luca Ghiotto (Trident) rounded out the top ten qualifiers.

[13][15] 15th-place qualifier Markelov misjudged his approach to Sainte Devote corner, locked his car's tyres, went airborne after driving over the kerbing and ran straight into a barrier.

[15] Gustav Malja (Rapax), Philo Paz Armand (Trident), de Jong and Jimmy Eriksson (Arden International) filled positions 16 to 19.

Sergio Canamasas (Carlin) was judged to have made the same error and Nabil Jeffri (Arden International) was observed to block Markelov and both drivers were required to start from the pit lane.

[18][19] Sirotkin made a slow start, allowing fellow front-row starter Nato to brake later than him and claim the lead into Sainte Devote corner.

On lap six, the first mandatory pit stops to change tyres were made by Giovinazzi, Ghiotto, Pic and Kirchhöfer in the lower end of the order.

This caused Latifi to clip the barrier alongside the circuit in the tunnel and retired in the pit lane with a bent front-left suspension.

[20][21][24] Then, as Sirotkin was quickly catching Nato, his car got into an uncontrolled sideways manoeuvre after clipping the kerb too hard at the exit of La Piscine turn and hit the wall for the second successive feature race.

[23] The VSC was used twice more for separate incidents that Ghiotto caused on lap 36 as he left debris on the racing line and hit the inside barrier at the Loews hairpin.

[24] Third was Rowland and the rest of the provisional order consisting of Lynn, Evans, Marciello, Giovinazzi, Kirchhöfer, Matsushita, de Jong, Pic, Canamasas, Gelael, Malja, Gasly and Armand.

[33][34] Behind the duo, Maricello went defensive against the fast-starting Evans and Nato went to the outside of Rowland to overtake him but he could not pass Lynn as the field were approaching Casino corner.

[36] Yellow flags were briefly waved by course officials on the fourth lap as King was about to pass Armand for 18th but he left the latter without enough space to get by and put him into a wall at the Loews hairpin.

[31][33][36] Sirotkin's poor season continued when the on-board fire extinguisher in his car was activated by debris from his tyre at the entry to Massenet turn on the 11th lap.

[36] Off the podium, Evans took fourth and fifth-placed Alex Lynn led a pack of cars comprising Nato, Rowland and Markelov who were covered by 1.3 seconds in positions six through eight.

[33] The final classified finishers were Pic, Canamasas, de Jong, Malja, Gasly, Ghiotto, Eriksson, King, Jeffri and Giovinazzi who stalled on the grid.

Markelov was delighted to achieve his first win and stayed on the soft compound tyres because his team deemed their pace decent, "We really did a good job together.

"[39] Nato, who came second, stated that he was displeased and angry over seeing Markelov take the lead as he did not feel the need to change tyres and was urged by his engineer to pressure him, "I tried to overtake him before Turn 5 and when I saw I couldn’t do it, I just focused on the end of the race.

"[40] Third-placed Marciello called his race "boring" because he found it difficult to overtake Kirchhöfer and hoped for a safety car or an extended VSC.

Nevertheless, he said he was still happy and wanted to continue the form into the Baku round, "It’s still a good weekend with Artem’s P1 yesterday and my podium today but we need to improve during the qualifying.

"[28] Valentin Khorounzhiy of motorsport.com wrote that the changes in gap were unlikely to account for Markelov's reaction time but for where on the track the VSC was activated as some drivers slowed to a different extent.
