White Sox sign relief pitcher Steve Cishek to one-year deal

Steve Cishek

The White Sox on Tuesday moved to increase their bullpen depth by signing veteran relief pitcher Steve Cishek to a one-year, $6 million contract.

Cishek, 33, will earn $5.25 million in 2020. The deal includes an option for 2021 worth $6.75 million, with a $750,000 buyout -- thus the $6 million guaranteed.

The right-hander spent the past two seasons with the Cubs. He appeared in 70 games in 2019, going 4-6 with a 2.95 ERA and seven saves. He struck out 57 and walked 29 with a 1.203 WHIP over 64 innings pitched.

Let's discuss the pluses and minuses of this signing in 3-up, 3-down format.

3 up

1. An ERA below 3.00 for four consecutive seasons. That 2.95 ERA in 2019 represents the *worst* season Cishek has had in recent memory. Over the past four years, his ERAs have been 2.81, 2.01, 2.18 and 2.95, respectively. Even if he regresses, he has a higher floor that some of the other candidates for the Sox bullpen, such as Carson Fulmer and Jose Ruiz.

2. Experience. Cishek is a veteran of 10 MLB seasons, and he's appeared in 572 games. His career ERA is 2.69, and while he likely won't be asked to close for the Sox, he has 132 saves lifetime. This is somebody who has been in his share of high-leverage situations. There's no reason he can't be placed in a seventh- or eighth-inning role.

3. Rubber arm. Cishek appeared in 150 games over the past two seasons, including a ridiculous 80 appearances in 2018. He's pitched in 60 or more games six times during his career. That reliability has to be respected.

3 down

1. A declining strikeout rate. Cishek struck out 10.0 batters per nine innings with the Cubs in 2018, but that declined to 8.0 batters per nine innings last season. His career mark is 9.5 strikeouts per nine innings, so he performed below his norms in 2019. There may be a little less swing-and-miss in his game going forward.

2. Overuse. I don't care who you are, 150 appearances is a ton over two years. In a way, it's a testament to Cishek that his former manager, Joe Maddon, trusted him that often. But sooner or later, that kind of usage has to take its toll. Perhaps that concern is among the reasons Cishek is only getting one year guaranteed on the open market.

3. An increasing home run rate. Cishek gave up 1.0 home runs per nine innings in 2019, which was the second-highest rate of his career. His career mark is 0.6 home runs per nine innings, which is the exact figure he was at during the 2018 season. Of course, to be fair, the ball was juiced last summer, so a lot of pitchers around the league saw an increase in their home run rate.

With the addition of Cishek, I think we can take a good guess at seven of the eight spots in the Sox bullpen. Here's how it most likely looks today:

Left-handers: Aaron Bummer, Jace Fry
Right-handers: Alex Colome, Kelvin Herrera, Cishek, Evan Marshall, Jimmy Cordero, ??????

Here are some candidates to fill in those question marks: Fulmer, Ruiz, Dylan Covey, Zack Burdi, Matt Foster and Ian Hamilton.
