NEW YORK — The Yankees enter the final weekend of August with a postseason race pressing on one side of the infield and a longer-term roster question pressing on the other.
Friday’s 1-0 victory over the Boston Red Sox at Yankee Stadium moved the Yankees to 76-58, four games behind Tampa Bay in the AL East and three games ahead of Boston for the top American League wild-card spot. The immediate focus remains October. The organization, however, also has to decide what its infield should look like once this season ends.
Jazz Chisholm Jr. sits at the center of that uncertainty. The second baseman has supplied speed and strong defense, but his offense has fallen from his 31-homer, 31-steal season in 2025. Through Friday, Chisholm was hitting .226 with 18 home runs and 38 stolen bases. He can become a free agent after the World Series, leaving the Yankees to decide whether another long-term commitment belongs in their payroll.
Ryan McMahon presents the opposite issue at third base. The left-handed hitter is batting .216/.282/.367 with 10 home runs and 32 RBIs. He has been on the 10-day injured list since Aug. 20 with a Grade 2 sprain of his left thumb. McMahon could return around roster expansion, but his contract runs through 2027 at $16 million next season.
That leaves New York balancing two different risks. Chisholm can leave. McMahon cannot without a trade. One has a rising price attached to his free agency. The other has a guaranteed season remaining despite modest offensive production. For a contender with a lineup under pressure, the question extends beyond the current postseason race and into how much roster flexibility the Yankees want at both positions in 2027.
The Yankees also do not have to solve that choice only through free agency or a trade. Their farm system has started presenting another possibility at precisely the right time.
A rookie has forced himself back into Yankees’ plans
Roderick Arias homered again Friday for Double-A Somerset. The switch-hitting Yankees prospect has gone deep in three of his last four games.
Arias is hitting .272/.354/.457 with 16 home runs, 78 RBIs and 34 stolen bases in 115 games across High-A Hudson Valley and Somerset, according to MLB and MiLB data through Friday. Both totals are career highs.
In 22 games since his Aug. 4 promotion, Arias is hitting .276/.344/.517 with four homers, 17 RBIs and 12 extra-base hits.
The turnaround is sharper by month. Arias hit .191 in April and May. A Pinstripes Nation calculation from his official game data shows a .319 average from June 1 through Aug. 28, with 14 of his 16 home runs during that span.
MLB Pipeline left Arias outside the Yankees’ preseason Top 30 after two uneven Single-A seasons. Five months later, his defensive destination is becoming almost as important as the offensive rebound.
Yankees are steering Arias toward second and third
Arias has appeared in 71 games at third base and 20 at second this season, compared with 19 at shortstop. He played second again Friday. That means 91 of his 110 defensive appearances have come at the two positions occupied by Chisholm and McMahon.
Baseball Savant’s minor league fielding data credits Arias with 17 errors at third and seven at shortstop. He has no errors in 20 games at second. Errors do not define a minor league defender, but the deployment matters more. The Yankees are testing him at positions that could offer a quicker MLB path.
MLB Pipeline has rated Arias’ arm among his better tools. His speed and switch-hitting profile also preserve second-base flexibility.
One split creates a possible 2027 bridge
Through Thursday, Arias was hitting .322/.374/.494 against lefties and .258/.348/.439 against right-handers. McMahon bats left-handed, so Arias could eventually complement him against certain lefties while covering multiple infield spots.
No Yankees official has announced that plan, and Arias has not played at Triple-A. His breakout has created an option, not a guaranteed succession.
The contract calendar still makes the fit notable. Chisholm can leave this winter. McMahon is signed only through 2027. If the Yankees retain Chisholm, Arias could develop behind both veterans. If Chisholm departs, second base could provide a faster opening. Third base could become available after McMahon’s deal expires.
Arias also faces a 40-man roster decision. He signed at age 17 in January 2022. Under MLB’s Rule 5 eligibility rules for players signed at 18 or younger, the Yankees are due to protect him after his fifth professional season or expose him to the draft.
Arias’ next test now has major-league meaning
The Yankees do not need Arias to solve their 2026 roster. Chisholm remains part of Aaron Boone’s lineup, and McMahon is progressing toward a return from the injured list.
What has changed is Arias’ place in the next infield decision. By Aug. 29, he owns career highs in home runs and RBIs, a productive Double-A introduction and a defensive schedule centered on second and third.
That does not make Arias an MLB regular yet. It gives the Yankees an internal option to evaluate before they decide how aggressively to pursue Chisholm, how to use McMahon in his final contract year and whether another expensive infield addition is necessary.
Arias began the season trying to revive his prospect status. He enters September with a chance to influence how the Yankees plan two positions for 2027 and beyond.
