The Cubs announced that they have selected the contract of right-hander Ethan Roberts from Triple-A Iowa. In a corresponding move to create a 40-man roster spot, right-hander Jose Cuas has been designated for assignment.
Roberts signed a minor league deal with Chicago back in December, and he had an opt-out in that contract on June 15, according to The Athletic’s Sahadev Sharma. Since Sharma indicated that Roberts chose to pass on that opt-out, it could be that he already had some advance notice that the Cubs were going to call him up soon to the majors, and the righty is now in line to receive his first MLB action since April 2022.
Roberts made his big league debut that season and posted an 8.22 ERA over 7 2/3 innings in the Show before injuries derailed his career. A Tommy John surgery in June 2022 kept Roberts on the shelf for the entirety of the 2023 season, and he only officially got back on the hill last month. Roberts has thrown 11 1/3 scoreless innings across three minor league levels — 9 2/3 IP with with Triple-A Iowa (9 2/3 IP), two-third of an inning in one Double-A game, and one inning of Arizona Complex League ball — but the spotless ERA masks the fact that Roberts has issued eight walks in those 11 1/3 frames.
Even though Roberts also had an inflated walk rate during his brief cup of coffee as a big leaguer, the control issues are a new problem for a pitcher who did a good job of limiting free passes earlier in his minor league career. It could be that Roberts was simply working off the rust after his long layoff, and the Cubs were still satisfied enough to select Roberts’ contract and add a fresh arm to their bullpen. For his minor league career as a whole, Roberts has a 2.84 ERA, 26.25% strikeout rate, and 7.08% walk rate across 139 2/3 innings (almost all as a reliever) since the Cubs made him a fourth-round pick in the 2018 draft.
Cuas has been optioned back and forth from Triple-A a few times this season, amassing a 7.43 ERA in 13 1/3 big league innings. Acquired from the Royals prior to last year’s trade deadline, Cuas has a 4.26 ERA in 116 1/3 career MLB frames since the start of the 2022 season, but control has also been an issue given his 12.1% walk rate.
Since Cuas is also still optionable for the 2025 season, rival teams might be interested in a waiver claim in order to add another reliever to their depth chart for more than just the current campaign. Cuas (who turns 30 later this month) has upped his strikeout numbers considerably over the last two seasons but has also had a subsequent spike in his walk rate.
