The latest from Ken Rosenthal

The Diamondbacks have shown "some" interest in Rangers first baseman Mark Teixeira, according to one industry source, but their offer is not as strong as those of the Braves and Angels, according to another.

The D-backs, 13th in the NL in runs per game, clearly would benefit from the addition of Teixeira. The question is whether they would be willing to meet the price in both players and dollars.

Teixeira, 27, is earning $9 million this season and his salary could rise to the $12 million range next season in his final year of arbitration before he becomes a free agent.

Diamondbacks first baseman Conor Jackson would be part of any package for Teixeira. Class AA outfielder Justin Upton would not.

"Justin Upton is the most untouchable player in baseball," one scout says. "You can tell `em that Mickey Mantle is coming back and they wouldn't do it."

The Angels' options will be limited if they fail to land Teixeira.

White Sox right fielder Jermaine Dye isn't a great fit for a team that already has four players for the outfield and DH spots and Juan Rivera possibly returning soon from a broken left leg.

A's designated hitter Mike Piazza also would be problematic because the Angels occasionally like to give breathers to Garret Anderson and Vladimir Guerrero in the DH spot.

Blue Jays third baseman Troy Glaus, another potential target, not only would need to waive his no-trade clause, but also would gain the right to demand a trade at the end of the season if he were dealt in the middle of a multi-year contract.
