MLB Teams Deal With Struggling Players as Marlins Slip Into Nine-Game Losing Streak

More than 30 MLB clubs have at least one underperforming player after the season’s first 100 games. Notable examples include Arizona Diamondbacks right‑hander Zac Gallen, who posted a 6.34 ERA over 19 starts and is on the injured list, Oakland Athletics infielder/outfielder Jeff McNeil, batting .238 with a –0.3 fWAR, and Atlanta Braves shortstop Ha‑Seong Kim, who has struggled both offensively and defensively after injuries.

Meanwhile, the Miami Marlins have endured a nine‑game losing streak, highlighted by a three‑game sweep by the Houston Astros. Pitching has largely held up, but the offense has managed three or more runs only twice in that span. Starter Sandy Alcantara showed flashes of effectiveness despite a rough outing in his most recent start. The slump underscores the volatility of the 162‑game marathon for teams seeking consistency.
