HOUSTON — Houston Astros pitcher Wandy Rodriguez is on a roll and wasn't about to let a bizarre incident with an umpire ruin it.

Rodriguez allowed one run and five hits over six innings to pick up his career-best third straight win, and Morgan Ensberg homered in his franchise-record sixth straight game in Houston's 3-2 victory over the Pittsburgh Pirates on Friday night.

In the first inning, Rodriguez was confronted at the mound by plate umpire Rick Reed after he called a ball. Reed said he didn't like the reactions he was getting from the pitcher. The incident led to Houston manager Phil Garner's ejection.

"The umpire was a little uncomfortable with me," Rodriguez said through a translator. "I just didn't pay attention to it. The pitch was inside and I thought it was a good pitch. My only reaction was 'Wow!' and he came running at and said, 'Don't do that again."'

Reed said Rodriguez shaking his head at some of the calls led to his action.

"In baseball, players don't like being shown up and umpires are professionals and we don't like to be shown up either," Reed said. "When he did it the second time I felt that he should be told in no uncertain terms it wasn't going to be tolerated."

Garner didn't have much to say about being ejected.

"I disagreed with the action," he said. "He obviously disagreed with my disagreeing."

Rodriguez (3-0) shook off the incident and didn't allow a run until Jason Bay's homer with two outs in the sixth inning.

Ensberg hit a two-run homer in the first, his seventh homer in the last six games and eighth of the season. He also leads the majors with a .411 average.

Chad Qualls and Dan Wheeler each pitched a scoreless inning before Brad Lidge came in the ninth.

Lidge struggled before earning his sixth save in six chances. He allowed two hits, including Craig Wilson's RBI single, and a walk before striking out Jose Castillo with men on second and third.

Jason Lane homered in the bottom of the sixth on a 1-0 pitch off starter Zach Duke (1-2) to push Houston's lead to 3-1.

Duke, who is from Clifton, Texas, allowed five hits and three runs while striking out four in six innings.

"Duke did a fine job," Pirates manager Jim Tracy said. "It was a quality start and he gave an opportunity for the club to win. I don't know how much more you can ask."
