HOUSTON, June 16 (UPI) -- Matt Dominguez drove in three runs to back Dallas Keuchel's strong start Sunday and Houston downed the Chicago White Sox 5-4 for a fourth straight win.
Dominguez got the Astros off to a 3-0 lead with a bases-clearing double in the second inning and Jason Castro added a two-run homer in the seventh, providing some much-needed insurance.
Keuchel (4-3) recorded a fourth consecutive start of allowing two or fewer runs, holding the White Sox to a pair of tallies on four hits over 6 1/3 innings. The left-hander walked two and struck out four.
Chisox starter Hector Santiago (2-5) was touched for three runs on five hits over 5 1/3 frames.
