Padres place Chris Paddack on IL, select Miguel Diaz

The Padres have placed right-hander Chris Paddack on the injured list and selected the contract of fellow righty Miguel Diaz, the team announced.

“I can’t really disclose a lot of information,” manager Jayce Tingler said of Paddack’s IL placement, via AJ Cassavell of MLB.com.

Tingler’s comment suggests Paddack is out for reasons related to COVID-19. Regardless, he’s the latest Padres starter to go on the shelf in the past couple of weeks, joining righty Dinelson Lamet (forearm) and lefty Adrian Morejon (Tommy John surgery).

Paddack was a standout for the Padres in his debut campaign, 2019, but he hasn’t been able to match his rookie production over the past season-plus. The 25-year-old hasn’t lasted more than 5 1/3 innings in any of his five starts this season, and across 23 1/3 overall frames, he has recorded a disappointing 5.40 ERA. However, some of Paddack’s other numbers — including a 3.22 FIP, a 3.66 xFIP, a 3.98 SIERA and a 6.7 percent walk rate — have been much more favorable.

Diaz, 26, appeared with the Padres in each season from 2017-19, but he could muster only a 6.61 ERA during that 66 2/3-inning stretch. The Padres non-tendered Diaz heading into the 2020 season, but they quickly brought him back on a minor league contract. They re-signed him to another minors deal prior to this season.
