After the series finale with the Astros, someone might be having second thoughts about the Rangers trading for Roy Oswalt.

Not Jon Daniels. Not Nolan Ryan. Maybe Roy Oswalt himself.

Oswalt had a bad game against the Rangers, one of the worst of his career, in fact. That certainly gives us fans pause about getting Roy O. on our roster. On the other hand, every pitcher has at least one terrible outing every year.

What really bothers me is how Oswalt looked on the mound Sunday night. To me, it looked like the heat was bothering him. If that’s the case, there’s no way I’d want Oswalt for the stretch run and I don’t think Oswalt himself would want it either. Thanks to this game, a lot of people are going to be looking at this trade in a new way.

I don’t have the time or inclination to do all the research on the subject, but Oswalt’s last batter faced was Matt Treanor, who worked Oswalt for 11 pitches before getting a base knock. This has to be the fifth or sixth time this season I have seen Treanor do this to a pitcher. He may be only a .235-.240 hitter, but he has given the Rangers some of the most quality at bats of any player this season.

What more can be said about Josh Hamilton? Sunday night, Hambone was a one-man wrecking crew. His second inning homer was the second longest in the history of Rangers Ballpark in Arlington at 468 feet. He extended his hitting streak to 21 games. He made two absolutely outstanding catches in left field and very nearly managed to throw out the only Astros runner to score. Josh has already tied a team record for most hits in a month with 47. With two games still to be played in June, there’s a good chance he’ll break that record.

Texas has been to the playoffs three times, in 1996, ’98 and ’99. I remember how those teams had great records after 75 games. The 2010 Rangers record of 46-29 after 75 games is better than all three of those division winners. We are now officially in heady territory.

After an off day, it’s three games in Anaheim. The best news is we could get swept by the Angels and still be in first place. I don’t think we’re going to get swept. That’s not discounting the Angels at all. They’ve been playing great baseball the past few weeks to stay within 4 1/2 of the Rangers. This is going to be a series of two teams that are both playing very good baseball at the same time. It’ll be a great test.
