Chafin (2-4) took the loss Wednesday against the Mariners after giving up one run on one hit and a walk in an inning of work.
Chafin entered to pitch in the bottom of the seventh with the game tied 2-2, and he walked the opening batter before allowing a base hit to put runners on first and third. Ty France was able to put the Mariners back ahead with a sacrifice fly that scored the runner from third and the Athletics weren't able to make up the deficit. It was Chafin's first run given up in six appearances since Sept. 15 and is his second loss this month. The self-proclaimed "failed starter" has been elite as a reliever this year with a 1.83 ERA, 0.93 WHIP and 64:19 K:BB over 68.2 innings.
