Chris Welsh recommends taking a chance on Dennis Santana from Pittsburgh as a speculative waiver wire source for saves, especially given the uncertainty around David Bednar’s current role. Santana's recent save opportunity was relatively clean and showcased promising stuff, giving leaders reason to consider him a viable closer, at least in the short term. However, Welsh warns that Bednar might eventually reclaim his position, limiting Santana's long-term viability. Despite this potential role volatility, Santana still represents a worthwhile gamble if you need immediate saves and can stomach some risk.
