The Cubs are going to designate first baseman for a signment, per . It appears he will be the corresponding move for , as reports that Mervis is being called up. The transaction comes as a surprise, since Cooper has generally been playing well. He signed a minor league deal with the Cubs in the offseason and made the Opening Day roster. Since then, hes hit .270/.341/.432 for a wRC+ of 118. Despite that strong surface-level production, there are also some concerning elements under the hood. Cooper has struck out at a 31.7% clip so far this year, a few ticks above his career rate, which was already a bit above average. He also has an unsustainable .391 batting average on balls in play, well above the .290 league average. Beyond Coopers performance, it seems that Mervis may have just forced the club into making a move. He had huge amounts of helium in 2022, despite landing with the Cubs as an undrafted free agent. The pandemic led to the 2020 draft being shortened to just five rounds and Mervis wasnt selected, leading to him signing with the Cubs afterwards Luis Rengifo Jersey . Despite being somewhat overlooked at that time, he shot onto everyones radar in 2022, going from High-A to Double-A and Triple-A, hitting .309/.379/.605 that year. That led to his first taste of the majors last season, though he hit just .167/.242/.289 in his first 99 big league plate appearances. He still hit well in Triple-A last year and is off to a strong start here in 2024. He has five home runs in 82 plate appearances this year and is drawing walks at a 14.6% clip, leading to a line of .288/.402/.606 and a 151 wRC+. Perhaps the club couldnt ignore that performance any longer, but handedne s may have also played a role. The Cubs as a team are hitting .284/.361/.506 against lefties for a 140 wRC+, second only to the Guardians. But against righties, their collective batting line is .236/.317/.381, which leads to a 97 wRC+ thats 17th in the league. Cooper hits from the right side and has been better against lefties in his career, but only modestly. Hes hit .285/.337/.475 against southpaws and .263/.337/.420 otherwise, leading to respective wRC+ counts of 119 and 108. Swapping in Mervis could perhaps give them a bump against right-handed pitchers since he hits from the left side. The Cubs could have perhaps bumped someone else off the roster in favor of Mervis, such as or , but those two offer a bit more defensively. Cooper is only really viable at first base, since his brief time in the outfield corners has yielded poor results. Madrigal and Wisdom can each play third while the latter has some outfield ability as well. There will now be a week for the Cubs to line up a trade for Cooper or pa s him through waivers. It seems fair to expect that there will be interest, based both on his performance so far this year and his track record. He hit .274/.350/.444 for the Marlins from 2019 to 2022, leading to a wRC+ of 117 in that stretch. He struggled to stay healthy in that time and then slumped last year, but he seems to be in good form so far this season. The Red Sox are going to be without their primary first baseman for a while, as has been . The Astros are getting from thus far. The same goes for the White Sox and , the Twins and and others. Given all of those different situations, the Cubs will likely be fielding calls about Cooper in the coming days. Brett Phillips Jersey
