Tunjo Tops Field in Wet Sunday Race at Mid-Ohio

Rain changed the conditions and the winners in Sunday’s second 45-minute IMSA VP Racing SportsCar Challenge race of the weekend at the Mid-Ohio Sports Car Course.

For overall and LMP3 winner Oscar Tunjo, Sunday’s 45-minute race marked his first trip to victory lane on an IMSA weekend. In the two GT classes, Adam Adelson (GTDX) and Kiko Porto (GSX) resumed their winning ways from earlier in the season.

Tunjo in the No. 31 Gebhardt Intralogistics Motorsports Duqueine D08 Nissan started second but completed an immediate pass of polesitting teammate Valentino Catalano in the No. 30 Gebhardt Duqueine at Turns 4 and 5 and set sail on his teammate.

Tunjo built the lead to over 10 seconds, a number fresh in the Colombian driver’s mind after a 10-second post-race penalty assessed on Saturday for changing columns prior to the race start.

He had a battle to conquer after a restart, with the field closing and Catalano now just one car length behind rather than multiple seconds behind as it had been most of the race. But Tunjo extended the gap to 1.279 seconds at the checkered flag to become the fourth different P3 winner in the last four races (Jonathan Woolridge, Catalano and Corey Lewis).

The GTDX battle showcased the ability of the drivers and the GT3-specification cars in these treacherous conditions, since they have both ABS and traction control available to them.

AJ Muss in the No. 66 Af Corse Ferrari 296 GT3 passed pole-sitting Jake Walker in the No. 6 Turner Motorsport BMW M4 GT3 for the lead, and a lap later Adelson in his No. 24 Wright Motorsports Porsche 911 GT3 R passed Walker for second.

Adelson then uncorked an excellent pass for the lead on Lap 9 out of Turns 4 and 5 and into the rhythm section of the track, Turns 6, 7 and 8 around the outside of Muss for the lead. As also shown in the rain in Round 2 at Daytona International Speedway, Adelson’s and the Porsche’s abilities in these conditions shone through on a gray day.

Adelson had contact in Turn 2 with Lewis’ No. 36 RAFA Racing Ligier JS P320 Nissan after the last restart, which sent the Saturday P3 winner’s car spinning around like a top. Because the contact was incidental, race control reviewed the incident with no further action and Adelson took home the win by 5.019 seconds over Muss with Walker third.

It’s Adelson’s third win of the year after sweeping the season opener in Daytona.

Samantha Tan rebounded to take the GTDX Bronze Cup win in her No. 38 ST Racing BMW M4 GT3 ahead of Saturday winner Vin Barletta in the No. 95 Turner Motorsport BMW.

She also highlighted her rain experience at Round 2 in Daytona as a key learning point to aid her success this race, securing her class-leading third Bronze Cup win of 2025.

The GSX race also saw an early-race lead pass, with Kiko Porto in the No. 8 RAFA Racing Toyota GR Supra GT4 EVO2 getting around pole-sitting teammate Ian Porter in the similar No. 68 RAFA Toyota for a lead which he wouldn’t relinquish the rest of the race.

The Brazilian scored his fourth GSX win of the year by 3.122 seconds over Chris Walsh, who won the Bronze Cup in class in his debut weekend with the No. 22 TWOth Autosport Porsche 718 GT4 RS CS. Like Adelson, Walsh also hailed the Porsche’s pace in the wet.

Saturday winner Steven Clemons finished third in the No. 76 BSI Racing Toyota GR Supra GT4 EVO2, bouncing back after a spin after Porter contacted him and was assessed a drive-through for incident responsibility.
