The Chicago Cubs have placed relief pitcher Jorge Lopez on the 15-day injured list due to a right groin strain, following a poor performance against the Pittsburgh Pirates where he surrendered two home runs. Lopez had previously missed time earlier in August with the same injury but was unable to perform effectively upon his return. In his absence, the Cubs have recalled right-hander Trey Wingenter from Triple-A Iowa; Wingenter has shown promise with impressive strikeout numbers in the minors. Since joining the Cubs, Lopez had maintained a solid 2.19 ERA over 22 games. The Cubs now look to Wingenter as a potential key player in their bullpen as they navigate the remainder of the season. This move highlights the team's ongoing adjustments as they prepare for critical games in October.
