Olivia Dunne cheers on her MLB boyfriend Paul Skenes during Pirates-Dodgers game

Olivia Dunne was spotted cheering on her boyfriend and MLB pitcher Paul Skenes in his showdown against Shohei Ohtani during the Pittsburgh Pirates-LA Dodgers game on Wednesday.

The 21-year-old model also shared a snap of her all-black outfit before the contest on Instagram, as she wore a bodysuit over mini jeans with a black Pirates cap.

Dunne - the top NIL earner among women in the US - was also at PNC Park - home of the Pirates - as she saw Ohtani - the reigning AL MVP - strike out against Skenes with a 100mph fastball in the first inning, as seen in footage on her Instagram Story.

Skenes - the first overall pick of the 2023 MLB Draft - ended up striking out seven more at-bats over five innings, as the Pirates defeated the Dodgers, 10-6, at home. 

He allowed three runs on six hits, including a two-run shot by Ohtani in the third. 

'His stuff... that first at-bat... was really good,' Ohtani said of Skenes. 'I couldn't put together good swings, but overall just really good stuff.'

Skenes also made light work of Mookie Betts' first appearance at bat, but eventually settled in and put steady pressure on the six-ft-six right-hander.

'I like to call that big on big because I obviously beat him a couple times earlier,' Skenes said of his battle against Ohtani, despite allowing the two-way Japanese star score.

'I think that was the right pitch to throw there, he's just a pretty darn good player. Stuff like that is going to happen.'

Skenes needed 91 pitches to navigate five innings even after being staked to the early lead. He showed a bit of growth in the fifth. Andy Pages homered and LA then loaded the bases with two outs. Skenes stayed in and he got Hernandez to ground out to third to end the threat and escape with a 7-3 lead.

'Good composure,' Pirates manager Derek Shelton said. 'He's going to give up home runs, but when you have an error and you load the bases, and again, having to grind through this lineup, it's not easy. 

'There's All-Stars throughout it. So very impressed with how composed he stayed.'

Last week, Dunne toasted her boyfriend's 22nd birthday on social media after the couple went out for a romantic, birthday dinner at a steakhouse in Indianapolis.

She also provided a witty response to a young Pirates fan who revealed his favorite thing about Skenes is his mustache and the Sports Illustrated model.
