Its Monday, August 18 and the Astros (69-55) are in Detroit to open a series against the Tigers (73-53) in a matchup of division leaders.
Spencer Arrighetti is slated to take the mound for Houston against Jack Flaherty for Detroit.
After taking two of three against the Red Sox earlier in the week, the Astros lost two of three over the weekend at home to Baltimore. They were outscored 23-5 over the course of the three games. The Astros lost 12-0 yesterday. Cristian Javier allowed one run in three innings in his second start since returning from the disabled list. He took the loss but the floodgates opened when Shawn Dubin came on in “relief” of Javier. The righthander allowed four runs in the fourth and the game spiraled out of control for Houston from there to the point where Chas McCormick pitched the ninth (ironically, the outfielder pitched a 1-2-3 ninth). Despite the woes of the weekend, Houston remains in first in the American League West by 1.5 games over Seattle.
The Tigers welcome Houston to Motown after taking three of four from the Twins in Minneapolis. After sputtering to open the month, Detroit is 7-3 in their last ten and 8.5 games ahead of Cleveland in the Central Division. Yesterday the Tigers gave up eight runs in the first four innings and were blasted by the Twins 8-1.
