On Sunday, the San Diego Padres announced they reached a deal with the Oakland Athletics for southpaw starter Sean Manaea.

Prospects Eruibiel Angeles and Adrian Martinez will be sent to the A’s, while minor-league pitcher Aaron Holiday will be sent to the Padres.

This four-player switch comes just days before baseball season begins.

Alongside Manaea, the Padres’ rotation also includes Joe Musgrove, Yu Darvish, Mike Clevinger, and Blake Snell.

Manaea made his first start for the Padres against the A’s just hours after the trade was revealed.

He is also reunited with manager Bob Melvin, who took over the Padres after leaving the A’s last season.

Back in 2016, when Melvin was still the manager of the Athletics, the now-60-year-old expected big things of Manaea.

“Once you bring a guy up like that, you’re looking at it more for the long haul,” Melvin said. “We think he’s ready to go. Now, you make your reps here in the big leagues based on performance — but we wouldn’t be bringing him here if we didn’t think he had the ability to stay here for a while.”

Manaea will be a back-end starter on a Padres’ pitching staff, which is expected to be more profound.

He was vigorously shopped by Oakland, and his name was frequently mentioned in MLB trade speculations. The Boston Red Sox, New York Yankees, and Minnesota Twins were allegedly among the teams interested.

In his final year of arbitration, the 30-year-old is set to make $9.75 million this season and will be a free of agent next offseason.
