A.J. Preller's total overhaul of the San Diego Padres roster continued this morning when the team dealt right handed starting pitchers Andrew Cashner and Colin Rea to the Miami Marlins. Padres reliever Tayron Guerrero was also traded to the Marlins. In return, the Padres get right hander Jarred Cosart, reliever Carter Capps, and two top minor league prospects. Josh Naylor, Miami's first round pick in 2015 the Amateur draft heads to San Diego along with hard throwing pitching prospect Luis Castillo.

The Marlins entered Friday tied for the second Wild Card spot in the National League and they hope that Cashner and Rea can help bolster their rotation. Cashner had been the longest tenured Padres player, having joined the team in a trade from the Cubs in 2012, and he was in the final year of his contract. He is 4-7 with a 4.76 ERA this season, while Rea is 5-5 with a 4.98 ERA in 18 starts for the Padres.

This trade is another move by Preller to restock his farm system. Naylor was the best position prospect in the Marlins system, and he was hitting .269 with nine home runs and 54 RBI's in low-A Greensboro of the Sally League. Castillo was 7-3 with a 2.25 ERA at Jupiter in the High-A Florida State League. Naylor and Castillo are both probably two to three years away from joining the El Paso Chihuahuas, but Castillo is a level ahead and had been one of the Marlins' top pitching prospects. Cosart was 0-1 with a 5.95 ERA in just four starts in 2016. Capps is out for the season after Tommy John surgery in March. Cosart figures to immediately go into the Padres starting rotation to replace Cashner , while San Diego might fill Rea's spot with a Chihuahuas player. Michael Kelly could be on his way to the big leagues since he has pitched the best of any El Paso starter in recent weeks. The 23-year old began the season in high-A and shot through the farm system. In eight starts with the Chihuahuas, Kelly is 6-1 with a 4.54 ERA.
