Boston Red Sox placed utility infielder Isiah Kiner-Falefa on the injured list with left forearm inflammation. He underwent an MRI after missing Friday’s game against the Mariners. The arm had nagged him for more than two weeks and worsened after a Seattle flight. Kiner‑Falefa, 31, is batting .277 with two home runs, 13 RBIs and seven stolen bases this season.

He has started 31 games, 21 at second base, showing versatility across the infield. Boston recalled Anthony Seigler from Triple‑A Worcester to fill the roster spot. Seigler adds a right‑handed bat and defensive versatility, giving manager Alex Cora flexibility while Kiner‑Falefa recovers. This move shuffles a bench that has struggled for consistency.

The injury comes as Boston fights to stay above .500 in the AL East, and losing a second‑baseman could tighten the lineup. Kiner‑Falefa’s .277 average ranks among the team's better hitters, so his absence may dent run production. Seigler’s promotion adds a bat, and Cora may also look to call up a prospect from Worcester to cover base if needed. The club will need infielder.
