Every Sunday throughout the remainder of the season, we’ll be going over the best and the brightest in the Miami Marlins farm system. This week’s heroes are Isan Diaz and Jordan Yamamoto.

Using the FanDuel scoring system, I tracked each player’s output through the week of July 8-14. These 12 players scored the highest in the Miami Marlins minor league feeder system.

To get a little more in detail about it, hitters are graded on hits, extra base hits, runs, RBI, walks, stolen bases, and HBP. Pitchers are graded on wins, quality starts, earned runs, strikeouts, and total innings pitched. Hits, unearned runs, and walks are not involved with the computation.

Player of the Week

Isan Diaz

Isan Diaz scored the highest of everyone, with a total FanDuel score of 123.2. After going 0-for-4 on Sunday, he collected hits in the other five games through the week, raising his average from .229 to .243. He went eight-for-22 overall, with a double, two walks, four home runs, and 10 RBI.

Diaz is rated as Miami’s seventh ranked prospect overall. Through the season, he’s slashing .243/.362/.419 with the Jacksonville Jumbo Shrimp, with 11 home runs, and 44 RBI. Despite his strikeout problem (91 K’s in 343 plate appearances), he’s also drawn 50 walks.

Diaz was part of the Christian Yelich prospect haul from the Milwaukee Brewers. He joined the organization with Lewis Brinson, Monte Harrison, and our pitcher of the week.

Pitcher of the Week

Jordan Yamamoto

Yamamoto was a Miami Marlins acquisition over the offseason from the Brewers, as stated above. This week, he started two games for the Jumbo Shrimp. On Monday, he earned a no-decision in a 3-2 win over the Chattanooga Lookouts. He lasted six innings and struck out seven, allowing two earned runs on eight hits and two walks. In Saturday’s game, he earned a victory, striking out seven in five innings and surrendering two earned runs on four hits and three walks as the Shrimp topped the Biloxi Shuckers, 7-4. He lands on this list by virtue of scoring 79.2 on the FanDuel scale.

For the season, Yamamoto is 5-1 with a 1.92 ERA and a 0.97 WHIP between the Jupiter Hammerheads and Jacksonville. He’s collected 61 punchouts in 51 2/3 innings. Currently, he’s Miami’s 19th ranked prospect.
