Padres trade Andrew Cashner, Colin Rea to Marlins for prospects

According to multiple sources, the San Diego Padres traded right-handers Andrew Cashner and Colin Rea plus relief prospect Tayron Guerrero to the Miami Marlins this morning. In exchange the Padres will receive right-handers Jarred Cosart and Carter Capps, first base prospect Josh Naylor, and pitching prospect LLuis Castillo. Here's a quick look at the rookies/prospects involved.

Luis Castillo, RHP: A right-hander from the Dominican Republic, Castillo was originally signed by the San Francisco Giants in 2012 then traded to the Marlins in 2014. Castillo has pitched quite well this season, posting a 2.25 ERA in 100 innings in High-A with an 85/14 K/BB and 82 hits allowed.

Castillo is listed at 6-2, 170, age 23. He throws quite hard, timed as high as 100-101 in short stretches and working consistently in the mid-90s. Both his slider and change-up show at least average potential and he's done a good job throwing strikes this year, but opinions differ on whether he will start or relieve in the long run. He looks ready for Double-A in any event.

Tayron Guerrero, RHP: Tayron Guerrero was signed by the Padres out of Colombia back in 2010. He's been an interesting but erratic presence in the San Diego system, dominating at times but never quite putting everything together. This year he has a 5.30 ERA in 36 innings combined between Double-A and Triple-A with a 36/19 K/BB and 32 hits allowed.

He's a huge guy at 6-8, 210, age 25. He throws quite hard, 95-97 with higher peaks, and his slider flashes plus. Inconsistent command has kept him from taking a larger role to this point but there's never been any question about his arm strength and he could develop into a solid (or better) reliever.

Josh Naylor, 1B: Josh Naylor was drafted by the Marlins in the first round in 2015 from high school in Mississauga, Ontario. He moved directly to the Low-A level this year and has held his own, hitting .269/.317/.430 with nine homers, 22 walks, and 62 strikeouts in 342 at-bats.

Naylor is a left-handed hitter and thrower, listed at 6-0, 225, age 19. Despite his stocky build and first base profile he's swiped 10 bases in 13 attempts this year, which says something good about his baseball instincts and feel for the game given that he is a below-average runner overall. His glove is mediocre at present but could be average in time. Power is Naylor's calling card but he isn't a brute force slugger and has kept his strikeouts under control so far, showing very good hitting instincts according to scouts.

Colin Rea, RHP: The Padres drafted Rea in the 12th round in 2011 from Indiana State University. The Iowa native made his major league debut last summer but is still a technical rookie for 2016. He's made 18 starts for the Padres this year, posting a 4.98 ERA with a 76/44 K/BB in 99 innings with 101 hits allowed.

Rea is 6-5, 225, age 26. He features a diverse arsenal including a fastball that is consistently in the low 90s and tops at 96, a curveball, a slider, a cutter, and a traditional change-up. He's been inconsistent but projects as an inning-eating workhorse going forward for the Marlins.
