Rays second baseman Akinori Iwamura has been traded to the Pittsburgh Pirates in exchange for pitcher Jesse Chavez.
Chavez, a right-hander, led all major-league rookies with 73 appearances last season. He was 1-4 with a 4.01 ERA. The 26-year-old had a 3.19 ERA before the All-Star break.
Iwamura missed three months with a knee injury this year and played three seasons with Tampa Bay. He hit .290 with 22 RBIs in 69 games this year.
The trade means the Rays will have an open spot in the lineup to be decided in spring training. The battle will include former Biscuita Reid Brignac and Elliot Johnson and Sean Rodriguez, recently acquired from the Angels.
