Cubs just made a petty but perfect waiver move to annoy Brewers fans

Too bad the Chicago Cubs won't be playing the Milwaukee Brewers for the rest of the regular season, as that prevents Aaron Civale from exacting some revenge against his former team. With the deadline for postseason roster eligibility on Monday, the Cubs have claimed Civale off waivers from the Chicago White Sox.

Earlier this season, the Brewers traded Civale to the White Sox after the veteran starting pitcher grew upset over a move to the bullpen. The trade did wonders for the Brewers' offense as Andrew Vaugn provided a spark that was sorely needed.

If the Cubs and Brewers were to meet in October, Civale pitching against his former team could be just the thing to get in Milwaukee's head. At the very least, it would add to the cinema that is Major League Baseball's postseason.

Success like what Civale had during his first years in the Majors with the Cleveland Guardians continues to evade him. In 67 innings pitched since the trade to the White Sox, Civale had an ERA of 5.37. Civale had a FIP of 4.28 during his time on the South Side, so the Cubs could be hoping that an improvement in the defense behind him leads to some success during the final month of the regular season.

With Jameson Taillon on the IL and Michael Soroka still a few weeks away from returning, the Cubs needed depth for the backend of their starting rotation. While Walker Buehler may have been a better option, the familiarity between Civale and general manager Carter Hawkins likely led to the move on Sunday.

Brewers might regret what Cubs just pulled off on the waiver wire

To make room for Civale on the 40-man roster, the Cubs designated veteran relief pitcher Tom Cosgrove for assignment. An early-season addition for the Cubs, Cosgrove only appeared in 2 games for the team this season, spending the majority of his season with the Iowa Cubs.

With the move being made official on Sunday, Civale would be eligible for the Cubs' postseason roster in October. One thing is clear: the Cubs' front office is leaving no stone unturned as they prep the roster for the final month of the season. Assuming the Cubs make Carlos Santana's signing official today, the veteran first baseman would also be eligible for the team's postseason roster.
