The Mets' edition of bullpen musical chairs continued on Thursday afternoon, with right-hander Austin Warren called up and fellow righty Jonathan Pintaro optioned to Triple-A Syracuse.
Warren, 29, appeared in one game for the Mets in early May, tossing a scoreless inning against the St. Louis Cardinals.
With Triple-A Syracuse, Warren has pitched to 3.94 ERA over the course of 19 games, holding opposing hitters to a .241 batting average. He's also appeared in big league games with the Los Angeles Angels and San Francisco Giants during his career.
Pintaro, 27, made his big league debut on Wednesday night, allowing two earned runs on two hits with two walks and one strikeout against the Atlanta Braves.
The Mets have now made a transaction concerning the bullpen in six of the last seven days, as president of baseball David Stearns tries to ensure the Mets have fresh arms available on a daily basis.
