The New York Mets reacquired left-hander Jonathon Niese from the Pittsburgh Pirates on Monday for left-handed reliever Antonio Bastardo and cash considerations.
Niese is 8-6 with a 4.91 ERA in 23 appearances (18 starts) this season. The Mets shipped him to Pittsburgh in the offseason for second baseman Neil Walker.
Niese, 29, spent his first eight seasons with the Mets and won a career-best 13 games in 2012. He has a 69-67 career mark to go with a 4.00 ERA.
Bastardo, 30, has a 4.71 ERA in 41 appearances this season. He had a 2.98 ERA in 66 appearances for Pittsburgh last season before signing a two-year, $12 million deal with the Mets in the offseason.
Bastardo spent his first five-plus seasons with the Philadelphia Phillies. He is 24-19 with a 3.73 ERA in 382 career appearances (five starts).
