Cubs Promote Matt Mervis – MLB Trade Rumors

May 5: The Cubs officially selected Mervis’s contract this morning, as noted by MLB.com’s Jordan Bastian. In a corresponding move, infielder Edwin Rios was optioned to Triple-A Iowa. The club already had an open spot on the 40-man roster, so no additional move was required to select Mervis. Mervis will make his MLB debut in this afternoon’s game against the Marlins, playing first base and batting seventh.

Rios, 29, has struggled with the Cubs so far this season, albeit in a tiny sample of just 25 plate appearances, with a slash line of .100/.280/.300 and nine strikeouts. He figures to serve as infield depth for the club at the Triple-A level going forward.

May 4: The Cubs will select the contract of first base prospect Matt Mervis, reports ESPN’s Jeff Passan. He’s not with the team for today’s series finale in D.C. but will join the Cubs when they return to Chicago tomorrow to kick off a homestand with a series against the Marlins.

Mervis, 25, was a 39th-round pick of the Nationals back in 2016 but didn’t sign, instead opting to attend college at Duke. He wasn’t selected in the shortened, five-round iteration of the 2020 draft and wound up signing with the Cubs as an undrafted free agent.

That’s proven to be quite the find for the Cubs, as Mervis has laid waste to minor league pitching and established himself as one of the organization’s top-ranked prospects. Over the past two seasons, Mervis has skyrocketed from High-A to Triple-A (and now the Majors), batting a combined .305/.383/.615 with 42 home runs in 161 games across three minor league levels. That includes a torrid .286/.402/.560 slash and six home runs through his first 112 plate appearances in Triple-A this season.

Baseball America ranks Mervis fourth among Cubs farmhands, while MLB.com has him sixth. Mervis is generally regarded as an all-bat prospect, as he’s a sub-par runner and not a standout defender  at first base. BA’s report on him notes that a shortened swing and refined approach at the plate unlocked a new level of performance for Mervis in 2022, and he’s clearly kept that up in 2023, given that he’s walked (16.1%) nearly as often as he’s punched out (17%). The left-handed-hitting Mervis was awful against left-handed pitchers in his first pro season, but he improved to .268/.339/.529 against southpaws in 174 plate appearances last year and is 6-for-20 with two homers, two doubles, six walks and six strikeouts in 27 plate appearances against same-handed opponents so far in 2023 (.300/.482/.700).

Mervis’ ascension to the big leagues comes at a time when veteran first baseman Eric Hosmer is struggling, having batted just .250/.294/.363 in 85 plate appearances. Cubs first basemen are still hitting .296/.331/.470 on the season, though that’s skewed by the fact that the vast majority of Trey Mancini’s production has happened to come while he’s playing at first base rather than in the outfield or at designated hitter. Mancini is…
