As the fantasy baseball season enters its crucial late stages, managers are increasingly scouring the waiver wire for potential closers, a category known for its volatility and potential for significant gains. Teams do not necessarily need to be playoff contenders to provide valuable ninth-inning opportunities; consistent competitiveness and fluid bullpen situations are key.

In Oakland, Elvis Alvarado has emerged as a strong candidate for saves. Despite a rough start to the second half, Alvarado has since allowed just two earned runs over his last 16 innings, striking out 18 batters. He has recorded saves in his past three appearances. The Athletics' remaining schedule, which includes numerous matchups against division rivals and teams in contention, suggests frequent opportunities for close games where saves can be earned.

Miami presents another potential source of late-season saves with Pete Fairbanks recently placed on the injured list. Both Calvin Faucher and Michael Petersen are considered the leading candidates for the closer role. Faucher has prior experience, recording the team's most recent save and leading the Marlins with 15 saves last season. Petersen, however, has demonstrated superior efficiency this season with a 3.46 ERA and a 1.12 WHIP across 54 2/3 innings, which could lead the Marlins' staff to reward his performance.

Miami's schedule also features many divisional games and matchups against offenses that could lead to tightly contested contests, offering further save opportunities. Both Faucher and Petersen are likely to see save chances based on matchups and availability, making either a viable option for fantasy managers aiming to improve their standings.
