Royals Sign Relievers Luke Jackson and Genesis Cabrera to Minor League Deals

On Friday, Raising Royals, the Royals' Professional Development account, announced that they had signed MLB veteran relievers Luke Jackson and Genesis Cabrera to Minor League deals. Both pitchers are expected to report to Triple-A Omaha.

Jackson and Cabrera are older players, at 34 and 29, respectively. They should add some much-needed depth to the Storm Chasers bullpen, which has struggled outside of Eric Cerantola, Beck Way, Jose Cuas, and Andrew Perez. Furthermore, Jackson and Cabrera are bullpen arms that could fill in at the MLB level should injury befall someone in the Royals bullpen.

The 34-year-old Jackson comes over from the Mets organization, as he pitched in 7.2 innings total between Triple-A and Low-A ball. The righty was semi-productive with the Texas Rangers a year ago, posting a 4.11 ERA in 35.1 IP. However, his FIP was much higher at 5.01, and his K% and K-BB% were paltry at 15.8% and 3.3%, respectively.

In 4.2 IP with the Syracuse Mets, Jackson posted an 11.57 ERA, 1.93 WHIP, and 6.74 FIP. He also had a -22.7% K-BB%. On a positive note, his TJ Stuff+ profile was pretty solid, so he could rebound a bit if he can hone his command a bit in Omaha.

Jackson had a 106 TJ Stuff+ overall with three pitchers (changeup, slider, and four-seamer) with TJ Stuff+ marks of 100 or higher. He also limited hard contact, with a .300 xwOBACON overall. However, his whiff rate (19.4%), chase rate (23.6%), and zone rate (40.2%) were all paltry, illustrating his issues with command in Syracuse. 

As for Cabrera, he was last in the Phillies organization, pitching for the Triple-A Leigh Valley Iron Pigs this season.

In 15 appearances and 17.1 IP with the Iron Pigs, he posted a 10.38 ERA and 1.79 WHIP. However, his FIP was much better at 4.54, and he showed a strong ability to maximize strikeouts and minimize walks. He had a 26.8% K% and 15.9% K-BB%, both solid marks for a reliever. What hurt him the most in Triple-A was the long ball, as he allowed a HR/FB% of 17.6%.

When it comes to TJ Stuff+, he hasn't been as impressive as Jackson. That said, he showed a much better ability to generate swing-and-miss in Triple-A this year than the right-handed reliever. 

Cabrera had a 99 overall TJ Stuff+ with only two pitches hitting the 100 mark (his sinker and changeup). That said, he did generate a 29.9% chase and 32.6% whiff rate, both above-average marks. His xwOBACON was a bit average overall at .373, but he did a good job of minimizing hard contact on his sinker and curveball, as illustrated by his .304 and .260 xwOBACON marks, respectively.

The big key for Cabrera will be finding the strike zone, as he only had a 44.1% zone rate with the Iron Pigs this season. Both have Minor League contracts, so they will need to be added to the 40-man roster to get a call-up to the Major Leagues this season.
