(Sports Network) - Houston has suddenly hit the skids with four losses in its last six games, including a 4-1 defeat to Colorado Sunday.
Wade Miller (2-2) absorbed the loss despite allowing just two runs on six hits in seven innings for the Astros, who lost for the fourth time in their last six games. Miller added two hits, including an RBI single.
Outside of Miller, the Astros managed just three other hits in the defeat. Second baseman Jeff Kent was not in the starting lineup for the second straight game due to a sore right quadriceps but struck out as a pinch-hitter to end the game.
Colorado starter Joe Kennedy retired 12 of the first 13 batters he faced and held the top three hitters in the order -- Craig Biggio, Adam Everett and Jeff Bagwell -- hitless in 11 at-bats.
The Astros will hope to provide more run support for struggling righthander Tim Redding Tuesday, when they begin a three-game series against Pittsburgh at PNC Park. Redding is flirting with a move to bullpen or the minors with losses in each of his first three starts.
Last time on the hill, Redding was blasted for nine hits and eight runs over 3 2/3 innings in a loss to St. Louis. Redding was tagged for four homers, while fanning four and not walking anyone.
Redding has gone to the hill six times in his career against Pittsburgh, posting a 1-1 mark with a 3.73 ERA. The Rochester, NY native has allowed 37 hits and 13 earned runs through 31 1/3 innings of action versus the Pirates.
