Miami Marlins Trade Rumors: Four Possible Destinations for Starlin Castro

Milwaukee Brewers
The Situation
The Milwaukee Brewers lead the NL Central by 1.5 games over the Chicago Cubs. At 42-27, they currently hold the best record in the National League, and Yelich. I’ll just leave this here.
At second base, the Brewers have Jonathan Villar, who is slashing .277/.325/.410 in 60 games. Backing him up ably is Hernan Perez, slashing .260/.280/.386 in 51 contests. Second base isn’t the problem, though.
At shortstop, the Brewers seem to be working toward giving the spot to currently injured Tyler Saladino. In the meantime, 23-year-old Orlando Arcia mans the spot.
Arcia is slashing just .207/.241/.268 in 56 games. That’s not a small-sample-size. Saladino is much better at .324/.359/.622, but that’s over a 16 game picture.
Solution
If the Brewers are set on improving one key position in the leadup to the postseason, it would be shortstop. Castro can still play shortstop, and he’s definitely an upgrade over Arcia, and possibly Saladino.
The Return
Trent Grisham
Trent Grisham is the Brewers seventh-ranked prospect, a 21-year-old lefty-hitting outfielder from Fort Worth, TX. Rated either average or slightly above average in every category, he grades out best with a 55 field rating. Grisham has slashed .309/.424/.430 across four levels of minor league ball in the last four seasons. He has 71 stolen bases in 95 chances overall for a more-than adequate 74.7% success rate.
Tristen Lutz
Tristen Lutz is a 6’3″, 210 lb. 19-year-old outfielder from Arlington, TX. He grades out with a 60 arm for his best rating, and everything else is either rated 50 or 55. In two seasons of pro ball, he’s slashing .260/.337/.447 in 96 games, but again, he’s only 19.
Marcos Diplan
Marcos Diplan is a 21-year-old right-hander from the Dominican Republic. He’s posted a 26-18 record over three levels of minor-league ball in the last five years, with a 3.62 ERA, a 1.386 WHIP, and 419 whiffs in 416 innings. Diplan’s got a 60 grade on both his slider and on his fastball. His Achilles heel has thus far been his control. He walks over a batter per two strikeouts, with 38 in just 61 1/3 innings this season.
Mario Feliciano
Mario Feliciano is a 6’1″, 195 lb. 19-year-old catcher from Puerto Rico. In 143 games at four levels of minor league ball since 2016, he’s slashing .247/.307/.325. Defensively, he guns down 27% of would-be base stealers, so there’s work to do there. His .986 fielding percentage is promising though.
