Humber has pitched terribly for the Astros to start the season, as he has lost all seven of his starts while posting an 8.82 ERA. The right-hander has only managed to strike out 16 hitters in 33.2 innings, but has walked 13. Humber has also surrendered six home runs this season.
Dallas Keuchel will start on Friday in place of Humber. The southpaw made 16 starts for the Astros last season, posting a 5.27 ERA over 85.1 innings pitched. Keuchel actually walked more hitters than he struck out last season, not a good sign for his potential as a starter. The 25 year-old has thrown 16.1 innings of relief for the Astros this season with a 4.96 ERA.
Houston has also moved Erik Bedard back into the team's rotation, as the veteran pitcher will start for the team on Sunday. The team announced on Monday that Bedard was moving back into the bullpen for an indefinite period of time, but apparently changed their minds. The lefty has a 7.36 ERA over 22 innings pitched this season.
