Stefen Romero drew a bases-loaded walk to score Daniel Robertson in the bottom of the 12th inning to help the Rainiers emerge with a 1-0 win over the Fresno Grizzlies on Sunday at Cheney Stadium.
Robertson singled with one out and after a ground out by Boog Powell moved Robertson to second, Tyler Smith was intentionally walked before Efren Navarro walked to load the bases.
Casey Coleman (2-0) picked up the victory with a scoreless inning of relief. He worked around a walk by striking out the side in the top of the 12th to keep the game scoreless.
