PITTSBURGH — The song remains the same.

The Rockies lost a 2-1 ballgame Monday at PNC Park on a night when one key hit could have made all the difference. Instead, they hit 0 for 6 with runners in scoring position and left eight men on base.

On the road this season, Colorado is hitting .203 with runners in scoring position vs. a .313 average back home at Coors Field.

Fitting, then, that the Pirates scored the winning run on a two-out infield hit in the eighth inning. Yoshi Tsutsugo did the honors, grounding the ball to second baseman Brandon Rodgers, who almost made a great scoop and throw to nail Tsutsugo.

Instead, Ke’Bryan Hayes, who led off the inning with a single off Tyler Kinley, scored from third.

The Rockies, now 5-11 on the road, have lost 11 of their last 14 games after starting the season 16-11.

The Rockies walked a tightrope much of the night but their defense saved them from falling off earlier in the game.

A key moment arrived in the Pirates’ seventh. Rodolfo Casto’s leadoff double off reliever Ty Blach had the Rockies teetering. Castro advanced to third on Jack Suwinski’s sinking line drive to right field where Charlie Blackmon made a nice, sliding catch for the first out.

Next, Pittsburgh catcher Michael Peters hit a hard chopper to Rodgers, who fired to home. Rodgers’ throw was a bit off-target but catcher Elias Diaz made an excellent tag on Castro sliding home. Umpire Jordan Baker originally ruled Castro safe but the call was overturned upon video review.

Rockies starter Chad Kuhl, facing the team he began his career with and pitched for during his first five seasons, was not razor-sharp, as his four walks indicated. But he did his job, limiting the Pirates to one run on five hits over 4 1/3 innings. Kuhl needed 103 pitches (58 strikes) to maneuver through his evening.

The Pirates struck in the first inning. Ben Gamel drew a leadoff walk, took second on Kuhl’s wild pitch and scored on a double by Ke’Bryan Hayes.

Kuhl dodged trouble in the fourth, too, thanks to Colorado’s defense. Josh VanMeter ripped a one-out triple to left-center but he was stranded when Rockies catcher Elias Diaz, another former Pirate, threw out Rodolfo Castro trying to steal second base. Kuhl got Jack Suwinski to pop out to third baseman Ryan McMahon for the third out.

Colorado tied the game, 1-1, in the fourth without getting a hit.

Ryan McMahon drew a leadoff walk off starter JT Brubaker and advanced to third when Brubaker threw wildly into center field attempting to force McMahon at second base on Brendan Rodgers’ groundball. Randal Grichuk grounded into a double play but McMahon scored to knot the game.

Brubaker, who shut out the Rockies for six innings in Pittsburgh’s 7-0 victory at PNC last May, tossed 6 2/3 innings, giving up five hits and two walks while fanning four.
