I am not sure what kind of specific grass this is. It has thin blades that are sparse compared to some other grasses. The nodes are quite noticeable. The stem is round. The spike has some red/brown colouring within the green. @PLSC213
PLSC213 - The Stem is smooth and has no trichomes. Leaves are alternate on the stem. The flowering head is very distinctive and this plant is very common in North America.
