3. Tony Sipp

Sipp offers potential as one of the most balanced southpaws on the market, proving pivotal for the Houston Astros in several key situations last season. The Clemson alum has taken on a larger workload and improved his strikeout:walk ratio in each of the past two seasons.

Sipp received his first taste of postseason in October, logging 5.1 innings without an earned run against the New York Yankees and Kansas City Royals. Add that with his ability to mix speeds of his fastball, slider and changeup, Sipp could emulate similar success from last season that helped him finish second in holds (13) among his teammates.

Reasonable contract: 2 years, $7 million
