The Spaniard, a member of the LIV Golf League with Fireballs GC, is one of three International Series champions and Asian Tour members in the 156-man field teeing up at Pinehurst No.2 in North Carolina, along with team-mate and compatriot David Puig and Japan’s Takumi Kanaya.
The 24-year-old, last year’s St Andrews Bay Championship winner, has shown glimpses of form this season with a T15 in Hong Kong and a T10 in Singapore.
Chacarra, who won the LIV Golf Invitational Bangkok event in 2022, in only his fifth professional start, is returning to full fitness again after recovering from a long-standing hip problem.

Chacarra secured one of 11 berths in the US Open qualifier at Dallas Athletic Club in Texas last month, a clear indication that his form and fitness are coming together at just the right time.
He said: “It was a goal I had since I was young to play in a major, and one of the goals this season was to qualify for a major.
“Obviously when I made a decision to come to LIV Golf, I knew playing majors would be hard to qualify,” added the former world no.2 amateur.
“Even though I have been playing really well and have two wins already, it is always hard to get into majors, so having the chance to get in one and perform well under pressure was great.
“For the past year and a half I had hip problems, and for the first three events this season I still needed injections, and with the way my body was feeling it was hard to perform.
“But I have been feeling great for one month now, and I think you can see by the results. My game is getting to where it wants to be because I am healthy again.
“I still have some mistakes I can clean up, but I can see I perform and compete with the best when I am healthy, and I am healthier.”

Chacarra is one of a number of LIV Golf League players to feature regularly on The International Series, using the set of 10 elevated events on the Asian Tour as preparation to supplement his regular season schedule.
Following his US Open adventure, his calendar includes the $US2m International Series Morocco in early July, the perfect preparation for LIV Golf Andalucia the following week.
Chacarra, who finished a disappointing 41st at LIV Golf Houston at the weekend after a three-over final round, said: “I’m going to play as much as I can now I am healthy. The Asian Tour is doing a great job of improving and making things better, and with the bigger budgets and players on The International Series, it is great to add these events to my schedule. I am grateful for the opportunities we get.”
Compatriot and fellow Fireballs GC youngster Puig goes into the US Open on the back of some great form.
The Spaniard, last year’s International Series Singapore champion, advanced to his second consecutive US Open by shooting a 12-under 132 at the Lake Merced Golf Club final qualifier in Northern California.
The 22-year-old finished an impressive T3 behind Torque GC star Carlos Ortiz, this year’s International Series Oman champion, at LIV Golf Houston on the weekend.
He also won the Asian Tour’s season-opening IRS Prima Malaysian Open, and narrowly lost out on a second title after finishing runner-up to John Catlin following a thrilling play-off at International Series Macau presented by Wynn.
Japanese golfer Kanaya, last season’s International Series Oman champion, also secured one of 11 spots alongside Chacarra at Dallas Athletic Club.
The US Open, the third major championship of the season, takes place at Pinehurst No.2 in North Carolina from Thursday 13 June to Sunday 16 June.
