What happened: Kansas City Royals second baseman Michael Massey was struck by a pitch during the bottom of the first inning against the Houston Astros, prompting an immediate injury delay. The HBP occurred with the bases loaded, driving in a run to bring the score to 2-9 following a historic nine-run outburst by Houston in the top half of the frame.

Why it matters: The delay capped a chaotic opening inning at Kauffman Stadium that saw Astros slugger Yordan Alvarez hit two home runs, including a grand slam. For Kansas City, Massey's health is critical as he anchors the middle infield; any potential absence would strain a Royals lineup already struggling to keep pace in the AL Central standings.

What to watch: Medical staff will monitor Massey for swelling or structural damage to his hand. The Royals bullpen faces a heavy workload after the early exit of their starting pitcher.
