Trailing 3-0 going to the bottom of the fourth, the Rangers had the chance for a big inning, but it slowly evaporated. Blalock chased a fastball from Jarrod Washburn that was up and out of the zone on the way to a strikeout with runners at second third and nobody out.

The whiff dropped Blalock's average with runners on base to .200 for the season. When he flied out with a pair of runners on base for the second out of the seventh inning, it dropped the average to .196.

"I think I got caught kind of in between approaches on that at-bat," said Blalock, who has traditionally been a far more effective hitters with runners on base (.293 average entering the season) than with the bases empty (.258). "I was trying to do a little too much."

But after leaving four runners stranded between his fourth- and seventh-inning at-bats, Blalock honed his approach a little. He came to the plate in the 11th inning against Seattle closer Brandon Morrow determined not to chase anything up, and he was able to lay off a hard fastball, up and away, to begin the at-bat. Morrow then decided to challenge Blalock with something down. Blalock was able to get the head of his bat extended and drove the ball into the gap in right-center, scoring Michael Young with the tying run and Josh Hamilton with the game-winner.

RANGERS 6, MARINERS 5 (11 innings): The Rangers trailed on three occasions Wednesday before DH Hank Blalock's double lifted them to their second walk-off win of the season. The Rangers fell behind in the 11th when a throwing error by 3B Michael Young ultimately led to a run. In the bottom of the inning, Young led off with a single and Josh Hamilton worked a walk ahead of Blalock's laser beam shot to the gap in right-center.

The win was the Rangers' third straight, and Texas has now won nine of its last 11 and 11 of its last 15 games. The Rangers, who improved to 19-14, have won all four games against Seattle this season and seven of the teams' last eight meetings.
