Week 13 Waiver Wire Spotlight
Week 13 of the 2026 MLB season is shaping up to be a turning point for fantasy baseball managers seeking a competitive edge. With the trade deadline looming and rosters still in flux, a handful of under‑the‑radar players are emerging from recent hot streaks and favorable matchups.
Sam Antonacci has been a revelation this June, slashing .328/.438/.557 while delivering three home runs, 14 runs scored and three stolen bases. His ability to get on base and drive in runs makes him a prime candidate for immediate addition.
Andrew Vaughn continues to dominate left‑handed pitchers, posting a .465/.558/.791 slash line against them throughout the 2026 campaign. Upcoming games against the Chicago White Sox and the Milwaukee Brewers present a perfect opportunity to capitalize on his left‑handed success.
Alex Lange has seized the closer role for the Kansas City Royals, racking up six saves since taking over in June. His recent performances suggest he will continue to protect leads in the late innings, adding value in categories like saves and holds.
Tommy Edman is heating up, going 8‑for‑19 over his last five games since his season debut on June 17. The outfielder’s surge adds depth to the outfield pool and could provide a boost in batting average and speed.
Andrew Alvarez has been equally impressive on the mound, posting a 2.70 ERA and striking out 20 batters across four starts for the Washington Nationals. His recent form makes him a compelling add for any roster needing reliable starting pitching.
Heriberto Hernandez has been a power threat, hitting six home runs in June and maintaining a .273 average over the past couple of weeks. His recent surge could translate into a steady stream of RBIs and extra‑base hits.
Key Matchups to Watch
Looking ahead, each of these players faces a schedule that aligns with their strengths. Antonacci will meet the Miami Marlins, a team that has struggled against right‑handed hitters, while Vaughn’s left‑handed prowess puts him in a favorable spot against the Los Angeles Dodgers. Lange’s Royals are set to play the St. Louis Cardinals, a matchup that could yield additional save opportunities. Edman’s recent hot streak coincides with a series against the New York Mets, a venue where his speed can turn singles into extra bases. Alvarez’s next rotation includes a start against the Atlanta Braves, a team that has been vulnerable to high strikeout performances. Finally, Hernandez’s power surge is timed with a stretch against the Philadelphia Phillies, a lineup that has allowed multiple home runs in recent games.
