The Cubs activated Edward Cabrera from the injured list on May 20 and sent him to the mound to start against the Giants at Wrigley Field, restoring a spot in the rotation that the club had been short-handed for much of the week.
To clear room on the 26-man active roster, the Cubs optioned right-handed reliever Tyler Ferguson to Triple-A Iowa. Ferguson, who was acquired from the Athletics on May 7, had been recalled from Iowa on Tuesday when the club optioned Jordan Wicks; he did not get into the game against his former team before being sent down again.
The move matters because it returns a pitcher with a substantial workload this season. Before the roster change Cabrera had made 10 starts, posting a 4.00 ERA with a 1.352 WHIP, 47 strikeouts and 54 innings pitched. Those numbers gave the Cubs a clear immediate boost to a rotation that has been juggling availability and workload.
Durability, however, is the open question. Cabrera left an outing against the Brewers with a blister after throwing three innings and allowing four runs, one of them earned, and he missed two starts while on the injured list. He has had blister issues in the past, and that history is the main reason the return is not purely encouraging: the club has the arm back in the rotation, but the underlying health concern that put him on the IL remains.
What the roster move does not answer is how Cabrera actually performed in the start the Cubs gave him; the box score from that outing is not part of this report. The immediate consequence for the bullpen is concrete — Ferguson is back in Triple-A — but the larger test will be whether Cabrera can complete his turn without recurrence. The decisive facts the team and fans will watch next are his results in that start and any signs of the blister reappearing, because those two outcomes will determine whether the rotation stabilizes or the Cubs must shuffle arms again.
