Lilliquist has been in his role since last season, signing on with the Nats after he was dismissed by the Cardinals. He took over for Mike Maddux, who left the D.C. organization for the Cards. The irony of that swap is only furthered by tonight’s move, which occurred while Maddux dressed in the visitor’s clubhouse.

Clearly, the results have not been there this year for the Nationals, who improved this evening to 13-17. The bullpen has been a major culprit in the struggles, while the rotation has perhaps not been quite as sharp as might be hoped. Just what level of fault Lilliquist carries in that situation is all but impossible to assess from the outside, but the club obviously felt a change was in order.

Rizzo says that Menhart was chosen because he’s “hands-on” and “analytical” in his approach. Menhart has five years of experience running the organization’s pitching development efforts as the minor-league pitching coordinator.

Now, some coaching updates around the National League…

• Mark McGwire won’t be returning as the Padres bench coach for 2019, per MLB.com’s AJ Cassavell. McGwire is reportedly stepping down to spend more time with his family after two seasons as the bench coach in San Diego. Big Mac had previously spent three seasons apiece as hitting coach for the St. Louis Cardinals and Los Angeles Dodgers. For the Padres, they will seek to avoid an extended search to fill their three coaching vacancies for 2019 (bench coach, hitting coach, and infield coach).
• In other coaching news, the Washington Nationals will not be making any changes to their coaching staff prior to 2019, per Chelsea Janes of the Washington Post. Manager Dave Martinez returns for the second year of a three-year deal, hoping for a turnaround after a disappointing first year in Washington. Bench coach Chip Hale, hitting coach Kevin Long, and pitching coach Derek Lilliquist will return to buttress Martinez in the Washington dugout. Rounding out the coaching crew: former infielder Tim Bogar returns to the first base coaching box, Greg Maddux’s former personal catcher Henry Blanco returns to coach in the bullpen and longtime third base coach Bob Henley returns in his usual role.

The 51-year-old Lilliquist was dismissed as the Cardinals’ pitching coach at season’s end. St. Louis ultimately chose to replace him with former Nats pitching coach Mike Maddux, meaning the two clubs have effectively swapped their 2016 pitching coaches. Lilliquist spent more than a decade and a half with the Cardinals organization, including the past six years as their pitching coach and the two years prior to that as the bullpen coach.

Bogar, also 51, joins the Nats after a long run in the American League West. A bench coach with the Rangers in 2014, Bogar joined the Angels’ front office as a special advisor in 2015 and jumped to the Mariners organization the following year when Jerry Dipoto (with whom he worked in Anaheim) was named GM in Seattle. With the Mariners, Bogar spent two seasons as the bench coach. He’ll bring another experienced coach to the staff as well as one that is quite familiar with analytics due to his close working relationship with Dipoto. He’s also coached on the Red Sox’ staff in the past.

The 42-year-old Dillon was the Nationals’ hitting coach with Triple-A Syracuse in 2014-15 but has spent the past two seasons as a minor league hitting coordinator in the division-rival Marlins organization.

Ken Rosenthal of The Athletic first tweeted the news that Bogar had been hired. Chelsea Janes of the Washington Post first reported Lilliquist had been hired (also via Twitter).
