After testing the open market, right-handed starting pitcher Zac Gallen is re-signing with the Arizona Diamondbacks on a one-year contract, multiple media outlets reported Friday.

According to The Athletic, Gallen's deal is worth $22,025,000 -- the same value of Arizona's qualifying offer that Gallen rejected. The same report added that $14 million of the salary would be deferred.

Gallen, 30, was coming off his worst full season as a pro. He went 13-15 in 33 starts with a 4.83 ERA, 175 strikeouts and 66 walks. The losses, ERA and walks all marked career-worst numbers.

Gallen was an All-Star in 2023 and finished third in National League Cy Young Award voting after going 17-9 with a 3.47 ERA, a career-high 220 strikeouts and 47 walks in 34 starts (210 innings).

In 176 career major league appearances (all starts) for the Miami Marlins (2019) and Arizona (2019-25), Gallen is 66-52 with a 3.58 ERA. He finished ninth in NL Cy Young balloting in 2020 and fifth in 2022.
