Harrison claims No. 1 spot on Marlins' Top 30

MIAMI -- An infusion of young talent is gradually making its way up the Marlins' system, with a handful of prospects already reaching the big leagues.
Through promotions and progression, the Minor League system has changed in recent weeks, and now, so have its ratings in MLB Pipeline's latest Top 30 Marlins rankings.
Unveiled on Thursday, Miami's list has gone through a transformation. Outfielder Monte Harrison remains the organization's No. 1 prospect, and the 22-year-old outfielder is 80th on the Top 100 overall prospects list.
The player who's made the biggest leap is shortstop Jose Devers, the 18-year-old shortstop at Class A Greensboro. The cousin of Red Sox third baseman Rafael Devers, Jose Devers is 12th on the Marlins' list, up from No. 25.
Devers was acquired from the Yankees as part of the Giancarlo Stanton trade.
The player who fell the furthest was right-hander Merandy Gonzalez, who dropped from No. 16 to off the list.
Also entering the list are Miami's first four selections from the 2018 MLB Draft in June. Outfielder Connor Scott, the 13th overall pick, is fourth; Competitive Balance Round B selection, catcher Will Banfield, is seventh; second rounder, shortstop Osiris Johnson, is No. 13, and outfielder Tristan Pompey (third round) is No. 16.
Several prospects also are getting their chance in the big leagues, including right-hander Sandy Alcantara (No. 2-rated prospect) and right-hander Pablo López (No. 18). Outfielder Magneuris Sierra (No. 15) was recently called up to the big league club.
Early in the season, outfielder Braxton Lee (No. 29) was on the Marlins' Major League roster.
"Young guys, they are excited about being in the big leagues," Marlins manager Don Mattingly said. "They should always be working hard, but they're trying to impress. There's just an energy about a player at the beginning of his career. It's nice to always have that infusion of youth. It's been good."
Preseason, outfielder Lewis Brinson, was the Marlins' top prospect, but he has graduated from the rankings. Brinson was the regular center fielder until he went on the disabled list on July 4 with right hip inflammation. Further diagnosis revealed a bone bruise, and he will be out for an extended period.
Mattingly and the organization saw several of their Top 30 prospects during Spring Training, and said there are benefits to giving some a taste of the Majors.
"It's good to see, from the standpoint of actually watching them at the Major League level, and watching them perform," Mattingly said. "To see how they react. We can see how they work, their preparation. You find out a lot about a guy, being able to watch him. On the other side of that, they infuse a lot of energy into your club."
Worth noting
• Relievers Brad Ziegler and Adam Conley remain the subject of trade speculation. The Indians and Cubs are potential fits.
• Reliever Tayron Guerrero (left lumbar strain) tossed a scoreless inning with two strikeouts on Wednesday in a rehab game with Double-A Jacksonville. Guerrero threw back-to-back days, which is a sign that he is close to being reinstated. The hard-throwing right-hander will be in Miami with the Marlins on Friday, but may not be activated at that time.
• Alcantara, on the disabled list since July 4 with a right axillary infection, is scheduled to make his second rehab start with Class A Advanced Jupiter on Saturday. Alcantara threw a bullpen session on Thursday.
• Reliever Drew Rucinski, out with a right groin strain, also threw a bullpen session on Thursday at the Roger Dean Chevrolet Stadium complex in Jupiter, Fla.
