Swindell was signed as a free agent to a $5.7 million, three-year contract at the end of 1998, and became a key cog of the bullpen, as the Diamondbacks made their first post-season appearance. In that campaign, the then 34-year-old led the team in appearances and was likely the best reliever, with a sparkling 183 ERA+. He threw 3.1 scoreless innings in the playoffs, though Arizona didn’t make it past the Division Series. That wasn’t the case two years later, when Swindell was again an important part of our NL West-winning side. His 64 appearances there were behind only Byung-Hyun Kim, and Greg pitched seven times that post-season, allowing one run over 4.
