Nationals promoting pitching prospect with strikeout upside

Washington Nationals pitcher Mitchell Parker

The Nationals will call up left-hander Mitchell Parker on Monday to make his major league debut.  Grant Paulsen of 106.7FM Radio reported the news earlier Sunday and Nats manager Davey Martinez confirmed to reporters that Parker will start Washington’s game against the Dodgers on Monday.  Right-hander Amos Willingham was optioned to Triple-A today, which makes room for Parker on the 26-man roster.

Parker was a fifth-round pick for the Nats in the 2020 draft and was added to the team’s 40-man roster last November in advance of the Rule 5 draft so another club couldn’t select the 24-year-old.  MLB Pipeline ranks Parker as the 21st-best prospect in Washington’s farm system, while Baseball America puts the southpaw 29th.

The strikeout potential has always been there for Parker, who has a 28.88 K% over his 329 2/3 career minor league innings.  Parker’s top pitch is a 55-grade fastball that averages roughly 93 mph with a ton of break, and he also has a plus curveball that works particularly well as a complement to his fastball.  However, controlling either of these pitches or his other offerings has been Parker’s biggest challenge, as his 11.6% walk rate is on the high side.  Parker has pitched in only four Triple-A games, with an underwhelming 7.53 ERA over those 14 1/3 innings with Rochester.

Some evaluators feel his ultimate future is in the bullpen, but Parker has started 72 of his 76 games in the minors and the Nationals figure to at least give him a trial run as a starter before deciding on a possible turn to relief pitching.  Facing the star-studded Dodgers lineup is quite a way to hit the ground running as a big leaguer, but Parker will get an opportunity as the Nats are still figuring out how to manage their rotation.

Josiah Gray was placed on the 15-day injured list last Tuesday, leaving MacKenzie Gore, Trevor Williams, Patrick Corbin and Jake Irvin as the District’s starting four.  It seems possible that Jackson Rutledge might’ve gotten the call ahead of Parker, but Rutledge might not be 100% after being hit by a comebacker earlier this week.
