Left-hander Jose Quintana and the New York Mets are in agreement on a two-year, $26 million contract, sources told ESPN, filling a gap in the team's rotation as it barrels toward the largest payroll in baseball history.

Quintana, 33, was brilliant for the St. Louis Cardinals after Pittsburgh sent him there in a trade deadline deal, posting a 2.01 ERA and allowing just one home run over 62⅔ innings.

He's expected to slot into the rotation spot vacated by Taijuan Walker, who agreed to a four-year, $72 million contract on Tuesday with the division rival Philadelphia Phillies, sources told ESPN.

The Mets, whose competitive-balance tax payroll currently clocks in around $298 million after the signings of Quintana and new co-ace Justin Verlander, still plan to add players, according to sources. Free agents from last year's team include center fielder Brandon Nimmo and right-hander Chris Bassitt, and they've shown significant interest in right-hander Kodai Senga, a free agent who has starred in Japan for the last decade.

After spending the end of a disappointing 2021 season as a reliever, Quintana found his prime self with the Pirates after signing a one-year, $2 million contract. While he averaged barely over five innings a start, Quintana had the lowest home run rate in the National League in 2022 and a nearly 3-1 strikeout-to-walk ratio.

Over his 11-year career, during which he has played for six teams, Quintana is 89-87 with a 3.75 ERA, 1,532 strikeouts and 504 walks over 1,723⅔ innings pitched.
