Oswalt faces potential suitor in series finale

Roy Oswalt will be pitching in Arlington on Sunday -- yes, still for the Astros in Interleague Play and not for the red-hot Rangers, who are reportedly interested in his services.

The Houston ace will be matched against fellow right-hander Tommy Hunter in the finale of the Lone Star Series as well as Interleague Play for both clubs.

The Rangers have expressed interest in Oswalt, who last month requested a trade to a contender, but there has been no reported movement in any trade discussions. The veteran Oswalt has four consecutive starts of seven innings or more, including a hard-luck ninth loss of the year in a matchup with the Giants' Tim Lincecum in his past outing.

With the Rangers taking Saturday's game to improve their season series edge to 4-1, the Silver Boot will stay in Arlington another year. While a win for the Astros on Sunday would be a step toward making June a winning month -- they're 12-12 thus far -- the Rangers picked up their 19th victory of June.

The Rangers, winners of 15 of their past 17, have mowed through Interleague Play to the tune of a 13-4 mark.

The Astros have found Interleague Play to be a difficult detour through the American League, having played the Rays (1-2), Yankees (0-3), Rangers (1-4) and Royals (1-2).

Said Astros manager Brad Mills: "That's how the ball bounces, so to speak. Sometimes you get those teams and sometimes you don't."

Astros: Checking on the DH
With Carlos Lee going 1-for-3 on Saturday, the Astros' designated hitter has gone 10-for-29 with five RBIs in eight Interleague games at AL parks. Entering Sunday's game, Lee had taken five of those DH spots, with Jason Michaels two and Jason Bourgeois one.

Rangers: Catcher rotation set
Rangers manager Ron Washington said he's liking the rotation of Matt Treanor catching three days then Max Ramirez for two, and so on. That sets up to have Treanor catching Sunday's game, since Ramirez caught each of the previous two games. "We're going to stay with it, unless something unforeseen happens," Washington said. "Right now it's working." Texas is 27-15 when Treanor starts behind the plate and 14-7 with Ramirez.

Worth noting
The Rangers are now 12-13 in day games with a four-game winning streak. The Astros are now 11-15. The Sunday finale is a night game.
