From Diamond Leung:
Brett Tomko will officially pitch out of the bullpen beginning Friday, and Hong-Chih Kuo is the favorite to start on June 2 in Pittsburgh. Grady Little hinted that Tomko did not take his demotion particularly well, and Tomko walked past waiting reporters in the clubhouse. You can follow Kuo's start in Las Vegas here.
Why Kuo and not Chad Billingsley?
