The Cubs announced their roster for Tuesday night’s season opener against the Dodgers at the Tokyo Dome (relayed by Taylor McGregor of Marquee Sports Network). As expected, Chicago officially promoted top third base prospect Matt Shaw. They designated reliever Keegan Thompson for assignment to clear the necessary 40-man roster spot. That move was foreshadowed when they left the out-of-options righty off their travel roster last week. Chicago also placed righty Javier Assad on the 15-day injured list with a left oblique strain.
Shaw’s promotion, while telegraphed once the Cubs announced he’d travel with the team to Tokyo, is the most significant of these transactions. The 23-year-old infielder figures to start at third base against Dodgers righty Yoshinobu Yamamoto in what’ll be his major league debut. It was a quick rise through the minors for the Maryland product. The Cubs drafted him 13th overall in 2023. Shaw hit .357 in 38 games in the low minors during his draft year. He continued to rake upon making the move to Double-A to start the ’24 campaign.
The righty-hitting infielder played in 86 games at the Double-A level. He hit .279/.373/.468 to earn a promotion to Triple-A Iowa in August. He performed even better at the top minor league level, closing the year with a .298/.395/.534 slash with seven homers across 35 contests. The Cubs cleared a path for him to take over the hot corner when they dealt Isaac Paredes to Houston as part of the Kyle Tucker blockbuster.
Chicago made a late-offseason push for Alex Bregman as a short-term deal became a legitimate possibility. Once Bregman agreed to terms with the Red Sox on a three-year deal, the hot corner because Shaw’s job to lose. While six exhibition games weren’t likely to move the needle one way or the other, he didn’t hurt his case by collecting five hits and three walks with only one strikeout in 19 Spring Training plate appearances.
Shaw is the consensus choice as the top prospect in a strong Cubs system. He ranks among the top 50 prospects in the sport at each of Baseball America, FanGraphs (Eric Longenhagen), MLB Pipeline, ESPN (Kiley McDaniel), and The Athletic (Keith Law). The various scouting reports project Shaw as a potential 25-homer bat with the ability to hit for a high average, though McDaniel and Longenhagen each express minor concern with his propensity for chasing sliders on the outer half. Shaw is regarded as a plus runner who should be capable of sticking on the infield.
A middle infielder by trade, Shaw will play mostly third base with Dansby Swanson and Nico Hoerner having the middle infield secured. Hoerner did not travel to Tokyo as he finishes his rehab from October flexor tendon surgery. The Cubs have maintained hope that Hoerner will be ready for next Thursday’s domestic Opening Day. Jon Berti seems the likeliest option to start these next two games in his place.
Shaw easily qualifies for the prospect criterion (on at least two of the preseason Top 100 lists at Baseball America, MLB Pipeline, and ESPN) of the CBA’s Prospect Promotion Incentive. If he sticks on the Cubs’ roster for a full service year, the team would receive an extra draft choice after the first round if Shaw either wins Rookie of the Year or finishes top three in MVP balloting within his first three seasons. Shaw will be under club control through 2030 and will qualify for arbitration during the 2027-28 offseason if he holds his roster spot. If he struggles and the Cubs option him back to the minors, that could obviously change his free agent trajectory.
More to come.
