The Cardinals placed Nolan Arenado on the IL with a shoulder strain after the trade deadline, following weeks of struggles at the plate.

One day after the Cardinals couldn't find a taker for Nolan Arenado, St. Louis placed the veteran third baseman on the 10-day injured list with a right shoulder strain. Arenado had sought a deal prior to the season but he used his no-trade clause to prevent the team from trading him to the Houston Astros.

Arenado has struggled offensively since the All-Star Break, leading to the Cardinals selling at the deadline. He has a .159 batting average and .417 OPS in 12 games since the break. The Redbirds are just 3-9 in those games, knocking them further back in the playoff race.
