Keuchel is not being considered for a start Sunday in Philadelphia, Nick Piecoro of the Arizona Republic reports.
Diamondbacks manager Torey Lovullo confirmed that Keuchel is not a candidate for Sunday's spot in the rotation, adding that the left-hander was on the taxi squad in the event of issues with COVID-19. Keuchel recently signed a minor-league deal with Arizona, which gives him a chance to work with his former pitching coach Brent Strom.
