According to Major League sources, the Rangers would likely want a package that included first baseman Conor Jackson, Minor League outfielder Carlos Gonzalez and one of Arizona's pitching prospects.
Teixeira would not only be costly in terms of the players the D-backs would have to give up to get him, but also in terms of finances. His 2007 salary is $9 million, which means the D-backs would be on the hook for roughly one-third of that this year and he's eligible for salary arbitration at the end of the year and could wind up making around $12 million next year before becoming a free agent.
The Rangers are also reportedly talking to the Braves, Dodgers and Angels about the 27-year-old switch-hitter, with the Braves offering Jarrod Saltalamacchia, Minor League pitcher Matt Harrison and shortstop Elvis Andrus and the Angels seemingly willing to part with pitcher Joe Saunders and Casey Kotchman.
The non-waiver trade deadline is 1 p.m. MST on Tuesday.
In 78 games this season, Teixeira is hitting .297 with 13 homers and 49 RBIs to go along with a .397 on-base percentage. His best season came in 2005 when he hit .301 with 43 homers and 144 RBIs.
While the D-backs do rank 13th in runs in the National League, it's not necessarily due to a lack of power as they are sixth in the NL in that category.
