Cardinals Activate Dominic Leone, Release Ryan Sherriff

The Cardinals have activated reliever Dominic Leone from the 60-day disabled list and placed fellow reliever Mike Mayers on the 10-day DL with right shoulder inflammation, Joe Trezza of MLB.com reports. Additionally, the Cardinals have released reliever Ryan Sherriff, according to Jenifer Langosch of MLB.com.

Leone is finally set to return after missing nearly four months with a nerve issue in his right biceps. Before Leone went on the DL on May 5, the 26-year-old opened the season with 13 innings of 4.15 ERA ball, adding 15 strikeouts against three walks. The Cardinals were counting on Leone to serve as a key member of their bullpen this year after a terrific 2017 with the Blue Jays, who traded him to St. Louis for outfielder Randal Grichuk in January.

Leone hasn’t been available for most of 2018, but Mayers, on the other hand, has seen plenty of action. The hard-throwing 26-year-old ranks third among Cardinals relievers in both innings (45 2/3) and appearances (42). Mayers has been respectable along the way, having logged a 4.14 ERA with 8.28 K/9 and 2.56 BB/9, but a couple of recent blowups have hurt his numbers. In a loss to Colorado on Saturday, he yielded two earned runs on three hits and failed to record an out – perhaps thanks to his shoulder troubles.

The left-handed Sherriff, 28, had been with the Cardinals since they used a 28th-round pick on him in 2011. He worked his way to the majors last year, impressing over 14 1/3 innings with a 3.14 ERA, 9.42 K/9 against 2.51 BB/9, and a 65 percent groundball rate. Sherriff totaled another 5 2/3 big league frames earlier this season, but he struggled before undergoing Tommy John surgery in June. Not only did that procedure end his season, but it’s also likely to keep Sherriff out for a large portion of the 2019 campaign.
