It was hinted at on Saturday but is now official.
According to MLB.com’s Jesse Sanchez, the Padres announced Sunday that top pitching prospect Casey Kelly will make his major league debut on Monday night at Petco Park against the Braves.
Kelly was acquired by the Padres back in December of 2010 as part of a four-player return package from the Red Sox for first baseman Adrian Gonzalez.
The 22-year-old former first-round pick has posted a 3.35 ERA, a 0.96 WHIP and a 39/3 K/BB ratio across 37 2/3 innings this season in the Padres’ minor league system. He missed the early part of the summer with a right elbow strain but is now fully healed.
Kelly ranked 76th this past winter on Baseball America‘s Top 100 prospects list. He was 31st in 2011.
The Marlins designated utilityman Derek Dietrich for assignment, Clark Spencer of the Miami Herald reports. This comes amid a flurry of moves on Tuesday night as teams prepare their rosters ahead of the Rule 5 draft next month.
Dietrich, 29, is coming off another strong season in which he hit .265/.330/.421 with 16 home runs, 45 RBI, and 72 runs scored in 551 plate appearances. He played all over the diamond, spending most of his time in left field and at first base. Dietrich also played some second base, third base, and right field.
Dietrich is entering his third of four years of arbitration eligibility. He earned $2.9 million this past season and MLB Trade Rumors projects him to earn $4.8 million in 2019. Cutting Dietrich represents a bit more than 4 million in savings for the rebuilding and perennially small-market Marlins. Dietrich should draw some interest, so the Marlins could end up trading him rather soon.
Wonder how J.T. Realmuto, now the longest-tenured Marlin, is feeling right about now.
