Keller has been great this season and he has allowed a maximum of 3 earned runs in the same game this season. The Mariners have scored a total of 32 runs over the last 6 games (5.33 runs per game) and have been good in that segment lately. Also over the same period the Pirates have scored only 15 runs and if the trend continues a win will be difficult to come by even if Keller has one of his good performances. You can expect Keller to be ok again but you should temper your expectation in daily fantasy formats if you select him.
