Yamamoto (7-2) picked up the win over Colorado on Saturday, allowing two runs on four hits over five innings while striking out six.
Yamamoto got knocked around a bit early on, giving up singles to three of the first five men he faced before also surrendering a solo homer to Ezequiel Tovar in the bottom of the third. The right-hander did, however, manage to retire seven consecutive batters from that point on before being relieved by Justin Wrobleski to open the sixth. It marked Yamamoto's longest outing since June 7, while he didn't issue a free pass for the first time in his last three starts. He now carries a 3.38 ERA in September to go along with a robust 21:5 K:BB.
