The late postponement of the game made for an annoying Friday night for everyone who had already gathered at Nationals Park and had to turn around and head home. It also created a new annoyance for the Nats, who must figure out how to fill out their rotation over the next week to account for today’s doubleheader.

Teams have the ability to promote a 27th player from the minors for doubleheader games and often elect to call up a spot starter for one of the two games. In this case, the Nationals elected to promote reliever Andres Machado and have him available for both games.

Machado opened the season in the Nationals bullpen and posted a 2.45 ERA in 10 appearances, but was optioned to Triple-A Rochester once rosters had to be reduced from 28 to 26 at the end of April. He had less success with the Red Wings, allowing five runs and nine hits in seven innings since the demotion, but his experience and ability to provide more than one inning if needed made him the choice for today’s promotion.

“He’s been throwing the ball well,” manager Davey Martinez said. “Based on what we think (the Rockies’) lineup will be, and the righties they have, if we needed someone, we wanted to get a right-handed pitcher up here that can give us multiple innings.”

Aaron Sanchez, who had begun to warm up before Friday night’s game was postponed, said he was good to start today’s first game. Joan Adon will pitch tonight as originally planned. And Josiah Gray will remain on a normal schedule and start Sunday’s series finale.

MIAMI – A getaway game in the middle of a road trip before an off-day doesn’t usually bring a lot of news. The Nationals didn’t take batting practice on the field at loanDepot Park, so players were slow to arrive in the clubhouse, hanging at their lockers or getting some work in the batting cage tunnel.

A handful of players were catching the end of the Brewers’ extra-inning win over the Braves, watching their next opponent walk off their division rival in 11 innings.

Here's some pregame news and notes from our conversation with manager Davey Martinez before the Nats take on the Marlins:

* After a brutal stretch of 18 scheduled games in 18 days to start the season, the Nationals have benefited from one off-day in each of the last four weeks. But that will end after tomorrow’s day off, when they embark on another stretch of 17 scheduled games in 17 days, starting Friday in Milwaukee.

So Martinez wanted to take today as an opportunity to get the guys off their feet for a little bit while still getting their work in without actual batting practice.

We’re continuing our miniseries of minor league entries from this week’s conversation with Baseball America’s Kyle Glaser on the “MASN All Access Podcast.”

In the first edition, we looked at Luis García’s hot start to the season at Triple-A Rochester while wondering when he’ll get the call back to the majors and what’s holding him back now.

Along with García in Rochester is the Nationals’ top prospect in Cade Cavalli. After flying up the ranks in his first professional season last year, the former first-round pick is now trying to find sustained success at the highest level of the minor leagues before making his highly anticipated major league debut later this summer.

Cavalli is 1-2 with a 7.36 ERA in 22 innings over five starts with the Red Wings. He has held opponents to a .259 average while striking out 19 and walking 11.

“He has some of the best pure stuff in the minors,” Glaser said of Cavalli. “It's explosive, explosive stuff all the way around. The one thing that has kind of been the issue dating back to his days in college was despite how his stuff read on a radar gun, it was always a little more hittable than you expected. And we're seeing that now at Triple-A against some of the top-level talent in the minors. He struggled there last year, he's actually struggling there so far this year as well. The strikeout-to-walk ratio is not great.”
