Today: The White Sox have officially announced Montgomerys promotion. To open a space on the active roster, the team designated infielder for a signment. They had off waivers from the Brewers in May. He hit .190 with a .443 OPS over 23 games in Chicago, while splitting his time between second base, third base, and shortstop. The White Sox now have five days to trade Capra. If they cannot find a taker, they must place him on outright or release waivers. In an additional transaction, the White Sox reinstated left-handed pitcher from the 60-day IL and optioned him to Triple-A Charlotte. Because Montgomery was already on the 40-man and Ellard will e sentially take Capras spot, Chicagos 40-man roster remains at 38 players. July Ryan Malbrough Jersey 3: The White Sox will promote for this weekends series against the Rockies, reports of WITZ Radio in Indiana. Montgomery is already on the 40-man roster, so the Sox only need to make an active roster move. Its the first MLB call for the 23-year-old, wholl likely make his MLB debut tomorrow against Colorados . Chicagos first-round pick in 2021, the lefty-hitting shortstop was one of the sports top prospects not too long ago. Montgomery placed among Baseball Americas top 50 minor league talents entering each of the past three seasons. BA ranked him as the best prospect in the Soxs system each year from 2022-24. Montgomery is listed at 63 and 230 pounds, giving him big raw power potential for a middle infielder. A very patient plate approach led to strong on-base marks against low minors pitching, but he has had a tougher time against more polished arms. Montgomery spent all of last year at Triple-A Charlotte, where he hit .214/.329/.381 in 130 games. He connected on 18 home runs with a strong 12% walk rate but struck out in nearly 29% of his trips to the plate. Chicago needed to add Montgomery to the 40-man roster last offseason to keep him out of the Rule 5 draft. Hed surely have been selected despite the middling Triple-A numbers, so that was an easy call for the front office. They optioned him back to Charlotte to begin the season, and hes had similar concerns in his second crack at the level. He has struck out a third of the time while batting .218/.298/.435 in 55 games. While the season numbers dont exactly demand a promotion, theyre weighed down by an atrocious April. Montgomery had a serviceable May and was very productive in June, batting .281 with six homers and 11 extra-base knocks in 16 games. The plate discipline concerns persist he struck out 22 times while drawing only five walks in 71 plate appearances last month but hed shown enough from a power perspective for the team to give him a look. The Indiana native has played four games at third base this year but has otherwise been a full-time shortstop in his minor league career. Its unlikely the Sox would call him up if they werent prepared to give him everyday playing time at his natural position. Rookie has gotten the playing time there. Meidroth, acquired from the Red Sox in the trade, is hitting .260 with a solid .347 on-base percentage. He hasnt shown any kind of power, but the disciplined approach is probably enough to stay in the lineup. Meidroths defensive grades are serviceable, but most scouting reports project him as a second baseman. The Sox could slide him to the keystone and move to third base to push out of the mix. Sosa is a known commodity as a utility type as well, so the focus should be on getting Montgomery and Meidroth into the lineup on a daily basis. Paul Endacott Jersey
