Scherzer could be eligible to return on July 20 against the Atlanta Braves since the move is retroactive to July 10, Zuckerman adds.
The Nationals ace wasn't able to pitch at the All-Star Game in Cleveland as a result of the injury. Scherzer, 34, is having arguably the best season of his prolific career, averaging a career-high 12.6 K/9 rate with a 2.00 FIP in 129 1/3 innings.
The Nationals (48-42) are enjoying a resurgence, going 17-5 since mid-June to climb within six games of the Atlanta Braves for first in the National League East. Scherzer has gone 5-0 during that stretch, allowing only four earned runs in 37 innings.
