Giles gave up a solo home run to Didi Gregorius on Tuesday, but he struck out two during an otherwise clean eighth inning in the Astros' 5-3 win.
With the Astros holding a three-run lead entering the eighth inning Tuesday, manager A.J. Hinch deployed Giles as his setup man before turning to Luke Gregerson in the ninth inning. The home run Giles allowed may be a sign he hasn't shaken off the spring rust just yet.
