Jose Castillo

Padres left-handed reliever Jose Castillo will undergo Tommy John surgery, Kevin Acee of the San Diego Union-Tribune reports. This isn’t surprising news, as Castillo exited a sim game Tuesday with forearm tightness.

The 2021 campaign will go down as another injury-ruined season for Castillo, who threw only two-thirds of an inning in 2019 while dealing with a teres major strain and didn’t pitch in 2020 because of a flexor strain and a torn ligament in his hand. Considering the time it takes to recover from TJ procedures, the 25-year-old Castillo won’t take a major league mound again until sometime in 2022, and that’s if he doesn’t suffer any setbacks. He’ll be eligible for arbitration for the first time next winter.

While the Padres look like one of the majors’ best teams heading into this season, the loss of Castillo is at least a blow to their bullpen depth. A healthy Castillo could have made the team all the more formidable, as he recorded excellent numbers during his rookie year in 2018. He threw 38 1/3 innings then and put up a 3.29 ERA/2.53 SIERA with an eye-popping 34.7 percent strikeout rate.

Padres left-hander Jose Castillo will miss roughly six weeks after being diagnosed with a teres major strain, manager Jayce Tingler told reporters Thursday (Twitter link via Dennis Lin of The Athletic). The 24-year-old southpaw exited Wednesday’s intrasquad game with what the team initially termed a possible lat injury.

It’ll be the second straight season with a notable injury for Castillo, who was limited to 8 2/3 innings between Triple-A and the Majors last year. He opened the 2019 season on the IL due to a flexor strain and suffered a torn ligament in his hand in his first and only big league appearance last year.

The six-week absence could sideline Castillo for nearly half the truncated 2020 season, and Tingler acknowledged that it might take him out of the 2020 equation entirely. “We’re going to need some breaks for him to return to play this year,” the manager said. “We’re going to stay optimistic.”

Castillo, acquired from the Rays in the three-team blockbuster that sent Wil Myers to San Diego and Trea Turner to D.C., was excellent in his 2018 debut campaign. After pitching to a combined 2.05 ERA in 26 1/3 innings between Double-A and Triple-A, he got the call to the big leagues and worked to a 3.29 ERA with a 52-to-12 K/BB ratio in 38 1/3 frames for the Padres. Armed with a fastball that averages 95 mph and a slider that has befuddled left- and right-handed hitters alike, Castillo generated a hearty 14 percent swinging-strike rate that season and looked to be on his way to establishing himself as a quality long-term piece in the Friars’ relief corps.

That may still prove to be the case, but it’s hard not to have some degree of concern with the arm injuries that have already begun to pile up for the promising young lefty. Drew Pomeranz, Matt Strahm, Adrian Morejon and likely fifth starter Joey Lucchesi are the only other southpaws on the Padres’ 40-man roster, although the team’s 60-man player pool includes non-roster a trio of lefties: Joey Cantillo, 2018 first-round pick Ryan Weathers and uber-prospect MacKenzie Gore, who could eventually push for a spot in the rotation in 2020.

Padres southpaw reliever Jose Castillo left the team’s intrasquad game Tuesday with a possible lat strain, Jeff Sanders of the San Diego Union-Tribune reports. Manager Jayce Tingler said he expects to have more information on Castillo’s status in the next couple days.

While it’s unknown how severe the injury is, lat strains often lead to weeks-long absences. With that in mind, it’s in question how much the 24-year-old Castillo will be able to contribute to the Padres over a 60-game season. For now, it appears he’ll be in for a second straight injury-limited campaign, having made just one appearance in the majors last year because of forearm and finger issues.

When healthy, the hard-throwing Castillo has shown he’s capable of serving as a key member of the Padres’ bullpen. As a rookie in 2018, he recorded highly promising production across 38 1/3 innings with a 3.29 ERA/2.64 FIP and 12.21 K/9 against 2.82 BB/9. Castillo shut down lefties and righties alike that year, holding opposing hitters to a woeful .170/.253/.267 mark.

Per MLB.com’s AJ Cassavell, promising Padres reliever Jose Castillo will miss the remainder of the 2019 season with a torn hand ligament (Twitter link). No surgery will be required, although this is certainly bitter news for a San Diego organization in sore need of bullpen aid.

After a solid 2018 debut in which the lefthanded Venezuelan logged a 3.29 ERA (2.64 FIP) in 38.1 innings, San Diego was likely looking for Castillo to develop into a viable bridge to vaunted closer Kirby Yates. Unfortunately, Castillo was sidelined for the entirety of 2019 with a left forearm flexor strain, until his activation this week. It was in his very first appearance back with the club on Thursday that Castillo exited a game with what at the time was believed to be a finger blister. As it turns out, the problem may end up being much more severe than the primary diagnosis indicated.

In a conference with The Athletic’s Dennis Lin, Padres manager Andy Green explained that the “pulley system” that straps a tendon in the middle finger to the bone was torn in Castillo’s hand (Twitter link). It is fair to speculate that Castillo’s return to the 60-day list will follow in due course.
