Patrick Saunders of the Denver Post reports that Rockies pitcher Tyler Anderson will undergo surgery on his left knee. It won’t be known until after the procedure if Anderson will be able to return at some point this season.

Anderson, 29, struggled over five starts this season, allowing 27 runs in 20 2/3 innings. He had been bothered by discomfort in his left knee since very early in the season. The Rockies demoted him to Triple-A Albuquerque earlier this month, but he hasn’t actually pitched for them due to the knee issue.

Jeff Hoffman is a candidate to take Anderson’s spot in the rotation. He has made one start in the majors this year and has otherwise pitched at Albuquerque.

MLB, union resume blood testing after pandemic, lockout

NEW YORK – In the first acknowledgment that MLB and the players’ association resumed blood testing for human growth hormone, the organizations said none of the 1,027 samples taken during the 2022 season tested positive.

HGH testing stopped in 2021 because of the COVID-19 pandemic. Testing also was halted during the 99-day lockout that ended in mid-March, and there were supply chain issues due to COVID-19 and additional caution in testing due to coronavirus protocols.

The annual public report is issued by Thomas M. Martin, independent program administrator of MLB’s joint drug prevention and treatment program. In an announcement accompanying Thursday’s report, MLB and the union said test processing is moving form the INRS Laboratory in Quebec, Canada, to the UCLA Laboratory in California.

MLB tests for HGH using dried blood spot testing, which was a change that was agreed to during bargaining last winter. There were far fewer samples taken in 2022 compared to 2019, when there were 2,287 samples were collected – none positive.

Beyond HGH testing, 9,011 urine samples were collected in the year ending with the 2022 World Series, up from 8,436 in the previous year but down from 9,332 in 2019. And therapeutic use exemptions for attention deficit hyperactivity disorder dropped for the ninth straight year, with just 72 exemptions in 2022.

Overall, the league issued six suspensions in 2022 for performance-enhancing substances: three for Boldenone (outfielder/first baseman Danny Santana, pitcher Richard Rodriguez and infielder Jose Rondon, all free agents, for 80 games apiece); one each for Clomiphene (Milwaukee catcher Pedro Severino for 80 games), Clostebol (San Diego shortstop Fernando Tatis Jr. for 80 games) and Stanozolol (Milwaukee pitcher J.C. Mejia for 80 games).

There was an additional positive test for the banned stimulant Clobenzorex. A first positive test for a banned stimulant results in follow-up testing with no suspension.
