Jack Flaherty experienced a noticeable dip in fastball velocity during his last start, averaging 91.4 mph in Game 5 of the National League Championship Series and triggering concerns about the state of his arm as the season stretched into late October. Flaherty, who will start Game 1 of the World Series for the Los Angeles Dodgers on Friday night, said the drop stemmed from a timing issue with his delivery that he has been working to correct throughout the week.
Dodgers pitching coach Mark Prior said the issue is not injury related, though he acknowledged being \"moderately concerned.\"
