He was placed on the injured list because of inflammation in his hand.
"Yordan has been suffering with the injury for a couple weeks and it's gotten worse," Baker said. The only way to get this well is to use these series before the All-Star break to coincide with the 10 that he has to be on the IL.
The injury that he sustained on a swing on June 18 was "bothering him every swing," Baker said.
The outfielder and designated hitter won't be able to play in the All-Star Game because of the next two series being missed.
He leads the Astros in hits, batting average, home runs, and on base percentage.
In order to make room for Jose, he was recalled from Sugar Land.
The Astros have a 12 game lead in the American League West over the SeattleMariners.
