The Chicago Cubs are hoping to get a late-season addition to their pitching staff in the form of Drew Smyly, and the veteran hurler took another step toward that vision on Sunday.

Smyly, who underwent Tommy John Surgery last year, has been slowly ramping up his work toward returning to the team, and he threw a simulated game at Wrigley Field Sunday before the Cubs took on the St. Louis Cardinals.

In 30 starts with the Tampa Bay Rays in 2016, Smyly posted a 4.88 ERA and a 7-12 record, striking out 167 batters.

It’s unclear whether the Cubs would try to have Smyly join the rotation or serve as a long-reliever, similar to the role that Mike Montgomery usually occupies with the team, but whatever the case, the team is thrilled with his progress back from his injury.
