The San Diego Padres filled a clear need in their starting rotation Wednesday, agreeing to terms on a four-year, $55 million contract with veteran right-hander Nick Pivetta, sources told ESPN's Jeff Passan.

Pivetta's deal, still pending the completion of a physical exam, includes opt-outs after the second and third seasons and is heavily backloaded. The contract will pay him a $3 million signing bonus and only a $1 million salary in 2025, then calls for salaries of $19 million, $14 million and $18 million from 2026 to 2028, sources told Passan.

The structure helps a Padres team that is trying to keep costs down for a second straight offseason and was already running a 2025 payroll of about $194 million, roughly a $30 million increase from where they were on Opening Day last year.

Pivetta, who will celebrate his 32nd birthday Friday, will likely slot in behind the Padres' incumbent trio of Dylan Cease, Yu Darvish and Michael King, leaving Matt Waldron and Randy Vasquez, among others, to compete for the fifth spot.

One of few reliable starting pitchers remaining on the free agent market, Pivetta has been lauded for his durability, extension and propensity for missing bats.

With the Boston Red Sox over the past four seasons, he averaged 156 innings, posted a 4.33 ERA and struck out 26.9% of hitters. Last year, while posting a 4.14 ERA in 145 innings, Pivetta finished with the lowest walk rate of his career at 6.1%.

Padres general manager A.J. Preller has navigated through a conservative, relatively quiet offseason since watching his team lose to the eventual World Series champion Los Angeles Dodgers in the National League Division Series.

Preller didn't make an addition to his major league roster until bringing back catcher Elias Diaz at the end of January. Days ago, the team agreed to $1 million deals with Connor Joe and Jason Heyward, who will make up a left-field platoon.

The Pivetta deal, occurring at the start of spring training, represents the first big move of the Padres' offseason. Given the absence of front-line starter Joe Musgrove, who will spend the year recovering from Tommy John surgery, it's an important one.
