Clemens opts to honor commitment to Longhorns

SEATTLE -- Kacy Clemens won't be following in his father's footsteps -- not to the Astros right now, at least.

The son of seven-time Cy Young Award winner Roger Clemens, who had a three-year stint with Houston toward the end of his career, announced Sunday he intends to honor his commitment to the University of Texas, rather than sign with the Astros.

The Astros drafted the younger Clemens in the 35th round (1,037th overall) of the First-Year Player Draft after he went 8-0 with a 1.09 ERA in his senior season at Houston's Memorial High School.

His father also attended Texas.

"It was great to hear his name called and always an honor to be selected," the elder Clemens told the Houston Chronicle. "His sights will be set on the 'The University' to get his education and get the 'Horns back to Omaha!"

Barnes returns to lineup, but hit streak ends at five

SEATTLE -- Astros fans won't have to worry about Brandon Barnes any longer, as the center fielder hit leadoff in Monday's series opener against the Mariners. Barnes missed Sunday's game against the Royals after leaving Saturday night's game with tightness in his left hamstring.

"I think he's fine. I mean, he actually came to me mid-game yesterday, and I told him to go see if it would loosen up," Astros manager Bo Porter said. "He came back and said, 'Bo, if I have to go in the game, I'll be fine.' So it's actually probably good we didn't play him yesterday, and hopefully it's behind him and we'll be able to move forward and not have any setbacks."

Barnes is hitting .282, ranking among the best rookies in baseball with at least 100 plate appearances, and is seen as important part of the Astros' future. He went 0-for-4 in his return to the lineup, snapping a five-game hitting streak in which he went 7-for-19 (.368).

"It's always nice to not have to worry about something that's nagging or a little injury here and there," Barnes said. "Just keep doing what I'm doing and not having to worry about injuries is good."

Worth noting

• The Astros signed seventh-round Draft pick James Ramsay, a center fielder from the University of South Florida on Monday. Ramsay hit .337 with three home runs to earn All Big East honors as a junior. The terms of the contract are undisclosed.

• The last time Houston first baseman Chris Carter was in Seattle, he went 8-for-15 with three homers as the Astros took two of three in an April series at Safeco Field. He also homered against the Mariners in Houston, and his four homers against them are the most of any player this season.

• The Astros are 14-14 when scoring the game's first run, but only 8-28 when their opponent scores first.
