Chicago Cubs: Robertson can serve a number of roles in a bullpen

David Robertson has been consistently reliable over the years coming into big situations. Spending most of his career with the Yankees, Robertson has a career 2.88 ERA, 2.81 FIP, 1.145 WHIP, 12.0 K/9 and 137 saves in 654 career games. He has exceeded the 60-inning mark every year going back to 2009.

Last season he pitched to a 3.23 ERA, 2.97 FIP and 1.03 WHIP with 91 strikeouts in 69 2/3 frames. He is 33 years old and has not shown any signs of slowing down. Only once since 2011 has he had a FIP above 3.00 (3.58 in 2016). He is reliable, consistent and durable. The ability to fill in as closer, set-up man or someone to put out a fire is exactly what Robertson has.

Overall he might be one of the most underrated relievers on the market. He could be a tremendous fit on the Cubs. He is probably not going to come cheap, but you would be paying for a guy you basically know what you are getting out of in a given season.
