Sheinin has the Bryce Harper-related news covered at the Sally League all-star game. Here are a few other notes from around the Nationals minor league system:

>>> The Nationals promoted infielder Stephen Lombardozzi from Class AA Harrisburg to Class AAA Syracuse, which sets up Lombardozzi for a possible call-up in September. At Harrisburg, Lombardozzi, who grew up in Columbia, Mary., hit .309/.366/.454 with four homers.

Just about every Nationals evaluator I’ve spoken with thinks Lombardozzi will be a big leaguer, and director of player development Doug Harris has compared him to Jamey Carroll – as steady as can be with an advanced approach at the plate. He played in the Arizona Fall League last year, a sign of how highly the Nationals think about him.

>>> Destin Hood will miss the Carolina League all-star game with sore knee; he had MRIs on both earlier this week and the Nationals do not believe there’s any structural damage, but he needs to rest. Infielder Jeff Kobernus will take his spot.

While Hood won’t be able to play, Harris was happy that Hood received the recognition. He’s raved about Hood since spring training, and he said opposing scouts, managers and coaches have given him compliments on Hood all season long. In the first half at Class A Potomac, Hood hit .276/.374/.467.

>>> The Nationals announced the signing of 18 draft picks, headlined by fifth-round third baseman Matt Skole from Georgia Tech. Several of those players have been playing rookie ball in Auburn for a few days now, so it’s not like this is Earth-shattering news.

Already, Nationals director of player development Doug Harris said, one of the signings has made a distinct impact: right-handed reliever Manny Rodriguez, 21, a 10th-round choice out of Palm Beach Community College. Rodriguez pitched a perfect inning Thursday and struck out one. Harris said Rodriguez (6-3, 225) throws about 92-94 with good downhill angle on his fastball. Among the full list, he might be a name to follow. Here is that list:
