Rapid Reaction: Red Sox 5, Rockies 3

BOSTON -- There was a time, not long ago, when you figured about the only way the names of John Lackey and Pedro Martinez would appear in the same sentence is if they got in a fender bender on one of Martinez's infrequent visits to the ballpark.

Not like this: Lackey striking out 12, matching his career high, while walking none in Boston's 5-3 win over the Colorado Rockies, a performance that put Lackey in the company of Pedro and a select few other Sox pitchers.

Lackey became just the sixth Sox pitcher since at least 1916 to strike out at least a dozen batters while issuing no walks. Martinez did it 10 times and Roger Clemens six, a list that includes Clemens's 20-K performance against the Tigers in 1996.

The other Sox pitchers to accomplish the feat were Hideo Nomo, Bruce Hurst and Jim Lonborg.

Lackey also became the seventh pitcher in the big leagues this season to have a 12-K-plus, no-walk game. The last was Eric Stults of the Padres on May 29.

Lackey's importance to the staff has become magnified since Clay Buchholz went on the shelf with injuries to his AC joint and neck, and he has stepped up in a big way. In his past eight starts dating to May 19, Lackey is 4-1 with an earned run average of 2.44. In his dozen starts overall, he has allowed more than three earned runs just twice.

He gave up a run in the first on a broken-bat dribbler by Carlos Gonzalez, stolen base and single by Wilin Rosario, and another in the sixth on a home run by Michael Cuddyer, who also homered off reliever Junichi Tazawa in the eighth.

The Sox, as they did in Tuesday's 11-4 win over the Rockies, jumped on a Colorado starter early, scoring all five runs by the time Roy Oswalt recorded the first out in the third, Daniel Nava's sacrifice fly.

Jacoby Ellsbury doubled for the fifth straight game to open the first and scored on Shane Victorino's single, one of three hits by the Sox right fielder. David Ortiz doubled him home and scored on Daniel Nava's base hit off the second base bag.

Singles by Victorino, Dustin Pedroia, Mike Napoli and Nava's sacrifice fly made it 5-1 in the third.

Jose Iglesias's streak of reaching base in 27 games with a plate appearance ended Thursday as he went hitless in four trips.

Koji Uehara recorded the save in his first opportunity since being named closer.
