Nearly three weeks later, Burnett has at least returned to the bullpen mound. He threw 25 fastballs Thursday, manager Clint Hurdle said, and the Pirates hoped to have him throw a light side session Saturday.
The 38-year-old right-hander, who will retire after the season, earned his first All-Star Game selection with a dominant first half then struggled in three starts after the break. He last pitched July 30, when he allowed 10 hits in 4 1/3 innings.
Burnett has said he hopes to return before the end of the season. He declined an interview request Saturday to discuss his status.
• Top Pirates prospect Tyler Glasnow struck out nine and allowed only four hits and two walks over 6 1/3 scoreless innings Saturday for Triple-A Indianapolis.
Glasnow has allowed three earned runs while striking out 34 batters and walking 15 in 27 1/3 innings over five Triple-A starts.
• Right-hander Vance Worley has pitched well since accepting his outright assignment to Indianapolis. Making his second Triple-A start Friday, Worley allowed one unearned run on three hits while striking out nine over seven innings.
