Dustin Pedroia continued his injury rehab assignment in Double-A Portland on Friday, but all indications suggest the aging vet has suffered another setback.


According to Red Sox manager Alex Cora, the second basemen "didn't feel right" and was pulled after four innings. "No slides, no hits. He didn’t feel right after the second one. He decided that was enough today," Cora said.


In the fallout, the four-time All-Star has been scratched from Portland's lineup on Saturday. Pedroia was reportedly in the initial card, but was replaced by prospect Brett Netzer just hours before the Sea Dogs' 1:00 p.m. start time.


Cora's quotes don't seem to be all that concerning, but the 35-year-old just can't seem to go more than a week without having issues with his surgically repaired left knee.


The former AL MVP has appeared in just nine games for Boston since the start of the 2018 season after undergoing the knee procedure in October of 2017.


What's all the more disconcerting is that Pedroia was making relative progress in his recovery before the setback. Though he is batting just .179 with one RBI in 12 games between Portland and Triple-A Pawtucket, he was able to play in five of six games before being transferred to Portland.


Unfortunately, however, playing several games in a row is now looked at as a considerable triumph in the latter stages of his career, regardless of his overall production.
