Pittsburgh Pirates rookie shortstop Konnor Griffin missed Thursday night's game against the Chicago Cubs because of right forearm soreness. The team listed him as day-to-day, making him available for future contests. Despite the injury concern, Pittsburgh kept him on their active roster rather than placing him on the injured list.

Griffin's absence comes just two months after the Pirates signed him to a nine-year, $140-million contract in April. The 20-year-old has shown promise in his rookie campaign, batting .261 with four home runs and 12 stolen bases across 49 games. His speed on the bases and developing bat made him a key piece in Pittsburgh's rebuilding plans.

Jared Triolo started at shortstop in place of Griffin during the series finale. The Pirates also shuffled their roster, recalling infielder Tyler Callihan from Triple-A Indianapolis while optioning outfielder Esmerlyn Valdez to the same minor league club. These moves give Pittsburgh additional infield depth during Griffin's recovery period.

Forearm soreness can often indicate more serious arm issues, so the Pirates will likely monitor Griffin closely. His development remains central to Pittsburgh's long-term strategy after investing heavily in the top prospect.
