Colorado’s Michael Cuddyer extended his hitting streak to 23 games with two solo homers, matching Dante Bichette’s club-record set in 1995.

Lackey (5-5) gave up two runs and eight hits without walking a batter. Mixing a fastball and slider most of the time, he had good command, throwing 73 of 98 pitches for strikes.

The Rockies finished a road trip in which they lost seven of nine.

Roy Oswalt (0-2), making his second start since being recalled from Double-A, allowed five runs and nine hits in six innings, striking out five and walking one.

Lackey, who missed all of last season rehabbing from elbow ligament-replacement surgery, struck out nine over the first four innings — getting three each in the first, second and fourth — while allowing Wilin Rosario’s first-inning RBI single.

The 34-year old right-hander had his 14th career double-digit strikeout game, first since Oct. 3, 2010.
New Boston closer Koji Uehara worked a perfect ninth for his second save.

The Red Sox wasted little time jumping to a 3-1 lead against Oswalt in the first. Jacoby Ellsbury had a leadoff double and scored on Victorino’s single to right. David Ortiz followed with his 499th career double, a drive high off the Green Monster that scored Victorino. Nava then had an RBI single when the ball bounced off the second-base bag and into short left just as shortstop Josh Rutledge was attempting to make a play on it.

Oswalt, 3-2 with a 2.16 ERA Double-A Tulsa, struck out 11 without allowing a walk in his first start against Washington last Thursday.

Boston increased it to 5-1 in the third on an Mike Napoli’s bases-loaded RBI single. He improved to 6 for 9 and four RBIs this season with the bases full. Nava followed with a sacrifice fly before Oswalt got the next two outs to strand runners on second and third.

In the sixth, the Rockies cut it to 5-2 on Cuddyer’s leadoff homer off a billboard above the Monster seats. They had runners on first and third with one out before Lackey struck out Tyler Colvin and got Yorvit Torrealba on a liner to center.

In the eighth, Cuddyer hit a different sign above the left-field seats leading off against Junichi Tazawa.
Colorado had grabbed a 1-0 lead on when Rosario singled after Carlos Gonzalez singled and stole second.
