Gleichowski said that he has been approached by five clubs expressing interest in Eckstein, who split last season between Toronto and Arizona. No dollar figures have been exchanged with any of those clubs.
Eckstein is pursuing an opportunity where he can sign on to be a starter, which isn't an offer the Pirates can currently make. However, that would certainly change if the Pirates do find a trade partner for shortstop Jack Wilson, or even second baseman Freddy Sanchez.
Though Eckstein has played almost exclusively as a shortstop in the Majors, he was groomed as a second baseman in the Minors and is believed to be intrigued by the possibility of moving back to his natural position.
The fact that the Pirates have put Eckstein on their radar suggests that there are ongoing talks to trade one of their middle infielders. The Pirates do appear to be losing options for a potential trade partner for Wilson, though.
The Tigers are out of the mix after signing shortstop Adam Everett. The Dodgers have made it known that their priorities are currently elsewhere. And despite speculation that the Twins could be interested, a Major League team source said that Minnesota is not pursuing Wilson.
Sanchez's name has not been attached to any interested teams at this time.
Eckstein hit .265 with 21 doubles and 27 RBIs in 324 at-bats last season.
