Things started smoothly for Rockies starter Tyler Chatwood, who looked strong in the first two innings. In the third, things started to come apart. Chatwood started the inning by allowing a hit to Mariners pitcher Sam Gaviglio, which was followed by a hit by pitch, a walk, and a wild pitch that scored the first run of the game. The other two baserunners scored on ground outs, giving Seattle a 3-0 lead.
The Rockies got a run back in the bottom of the third on Charlie Blackmon’s 13th home run of the year, and they got another in the fourth when Gerardo Parra singled home Charlie Blackmon, who had walked, cutting the deficit to 3-2.
Seattle got those two runs back in the fifth when Kyle Seager’s bases-loaded double brought home a pair and chased Chatwood from the game. Reliever Scott Oberg allowed an inherited runner to score, giving the Mariners a 6-2 lead going to the bottom of the fifth.
The Rockies scored a lone run for the third straight inning in the fifth, when Trevor Story led off with a solo home run to right against Gaviglio. They added two more in the sixth on a run-scoring ground out from Mark Reynolds and an RBI double by Parra, cutting the lead to 6-5.
That was as close as the Rockies would get, as the two bullpens combined to pitch 8 2⁄3 scoreless innings to close out the game.
Colorado will look to get back on track tomorrow as Tyler Anderson takes the mound at Coors Field against Ariel Miranda. First pitch is at 5:10 p.m. Mountain time.
