ST. LOUIS (AP) — St. Louis Cardinals right-hander Carlos Martinez has been scratched from his scheduled start on today (Tuesday), with a sore back. Martinez (13-6, 2.91) suffered the injury in his last start Thursday in Arizona.

Left-hander Marco Gonzales will be recalled from Triple-A Memphis to make the start against Washington. Gonzales is 1-4 with a 5.20 ERA in 13 starts. Cardinals manager Mike Matheny said Martinez is expected to miss just one start, adding “We’ve had our eyes open looking for a time to get him some rest.”
