The Toronto Blue Jays announced Monday that left-hander Steven Matz has tested positive for COVID-19 although he is currently symptom free.

Follow-up testing with the rest of the team all came back negative. Matz was placed on the COVID-19 list Sunday following an inconclusive test. 

Per MLB rules, Matz must isolate for 10 days beginning from the positive PCR result date.

The 30-year-old pitched in Saturday's 7-2 victory over the Boston Red Sox, as he allowed four hits and a run over 5 2/3 innings, striking out eight with two walks.

Matz is 7-3 this season with a 4.26 ERA and 1.35 WHIP. 

The Blue Jays will wrap up their series with the Red Sox on Monday before welcoming the New York Yankees to Buffalo beginning on Wednesday.
