Shortstop Brandon Crawford has played 114 of the Giants' 125 games this season. On Tuesday, he's taking the day off.
Giants manager Bruce Bochy is using right-handed bat Abiatal Avelino against Cubs left-hander Cole Hamels. Crawford is batting just .173 in August and certainly could use a breather.
Avelino, on the other hand, has hit .285 with 12 home runs in Triple-A for the Sacramento River Cats. The 24-year-old also has stolen 15 bases this season.
