Houston Astros scratch C Yainer Diaz with abdominal injury

HOUSTON -- Catcher Yainer Diaz was scratched from Houston's lineup about an hour before the start of a series against the Los Angeles Dodgers on Monday night because of a left abdominal injury.

Christian Vazquez took his spot in the lineup and was batting ninth.

With Diaz injured, the Astros selected the contract of catcher Cesar Salazar from Triple-A Sugar Land and optioned infielder Shay Whitcomb to Triple-A to make room for him on the roster.

The 27-year-old Diaz is hitting .248 with two home runs and 14 RBIs in 26 games this season for the Astros.
