Deep Dive: free agent left-handed relievers

Perfect timing: Will Smith saved 37 games for the Giants this year, and has the highest bWAR of any southpaw reliever in this year’s free agent class. (@White_Willy13)

“Deep Dive” focuses on the depth of each position in the Chicago White Sox organization. Each position is broken into a five-part series:

  1. Depth in the rookie levels (Dominican through Great Falls)
  2. Depth in A-ball (Kannapolis and Winston-Salem)
  3. Depth in the higher levels (Birmingham and Charlotte)
  4. Under the Radar-type detail on one of the White Sox players at that position
  5. Free agent options at that position

This article delves into the left-handed relief options available this offseason; as in most years, the pickings are slim.

Aaron Bummer clearly was the best left-handed reliever on the White Sox in 2019. However, the rest of the southpaw relievers struggled with control issues, injuries and/or overall ineffectiveness. What lefties are available who could supplant Jace Fry and/or Caleb Frare as the No. 2, or are any worthy of perhaps being the new closer? And is there anyone out there capable of being a fifth starter if injuries or ineffectiveness occur to someone like Reynaldo López? Below is an outline of left-handed free agents in this year’s class.

Despite my entire family being Cub fans, I grew up listening to Harry Caray and Jimmy Piersall on the radio as I listened to the entire season of the South Side Hit Men of '77. While it's true I have a myriad of other interests (American history, classic literature, classic rock, classic country, blues, jazz, gardening, family,etc.--not all in that order), few things aside from family surpass my interest in all things baseball--especially the White Sox.

It would be nice to get Will Smith to go along with Will Harris. Tony Cingrani is a South Side boy, so maybe he’d like to join the Sox for next to nothing?

Seems like he might be open to a MiLB deal to reestablish himself.

Cingrani is the only player I would want that will be available outside of Smith. Maybe Pomeranz as a swingman. Not bad low-cost options for us.
