These past few weeks have been good to Nolan Arenado, who’s been highly productive offensively for the Diamondbacks. However, Arizona will hope for good news on the third baseman, who left early on August 16. As for the Cubs, Dansby Swanson will likely be headed to the injured list.

Swanson headed to IL

Cubs shortstop Dansby Swanson was removed early on August 16, and it looks like he’ll be out for some time, beyond a one- or two-day absence.

Swanson, who left with an oblique injury, is expected to go on the injured list per manager Craig Counsell. The Cubs shortstop will get an MRI this coming week.

Arenado exits

Diamondbacks third baseman Nolan Arenado was removed against the Braves with what was originally called trunk discomfort. Arenado was visibly uncomfortable and favoring his side after he ran out a ground ball in the fourth inning.

Arenado, who indicated that he believes it’s an intercostal muscle strain, will undergo an MRI.

IL moves

The Red Sox placed outfielder Masataka Yoshida on the 10-day IL with a left hamstring strain. Additionally, pitcher Justin Slaten went on the 15-day injured list with right elbow inflammation.

Dodgers pitcher Justin Wrobleski went on the 15-day IL with left forearm inflammation.

The Athletics placed outfielder Tyler Soderstrom on the 10-day IL with a left hip impingement. Aside from that, Justin Sterner was transferred to the 60-day IL.

Rehab assignments
