The Giants had one of the biggest trade deadline days in franchise history. Certainly the biggest all-out deadline sale I can remember. Whent the dust cleared 6 players were traded off the Active Roster for a total of 8 prospects, most of them ranked in the top 10 of organizations they come from and 5 immediately slot into the MLB's Top 30 Giants Prospects. Here is a list of the players the Giants traded yesterday and today:
Tyler Mahle RHP
Luis Arraez 2B
Robbie Ray LHP
Caleb Kilian RHP
Erik Miller LHP
Heliot Ramos OF
Carlos Gutierrez OF(A+)
We all know who they are so I am not going to go into detail of their strengths and weaknesses. The only (slight) surprises were Ramos and Gutierrez. Ramos was traded for the prospect return he could get and because the Giants have several OF prospects they are hight on and need to open up positions where they can play. Gutierrez was throw-in on a deal for a former #4 overall draft pick.
Let's grind through the prospects the Giants got in return. I will list them in the order of where I rank them.
Ramon Marquez RHP(Phillies). DOB: 9/19/2005. 6' 2", 182 lbs.
Henry LaLane LHP(Yankees). DOB: 5/18/2004. 6' 7", 211 lbs.
Miguel Mendez RHP(Padres). DOB: 7/1/2002. 6' 2", 165 lbs.
2026(AA): 2-2, 4.93, 34.2 IP, 9.87 K/9, 4.41 BB/9, 1.19 GB/FB.
Broke out in 2025 after 4 years in A ball. Velocity spiked to 95-100 MPH. Tight slider is a "dynamite" weapon. Changeup is less developed. Improved control but still walks too many. Probably profiles as a RP.
Joniel Hernandez SS(Padres). DOB: 3/6/2009. B-R, T-R. 6' 1", 180 lbs
2026(DSL): .303/.424/.503, 15 2B, 2 3B, 4 HR, 4 SB, 16.7 BB%, 16.1 K%, 192 PA.
17 yo SS out of Cuba. $1.4 M signing bonus. Loose, whippy swing comes with some length but currently hitting for average in the DSL and showing excellent strike zone judgment. Projectable power in both the swing and frame. Run is best tool with a 60 grade. A lottery ticket, for sure.
Kaeden Kent SS(Yankees). DOB: 8/29/2003. B-L, T-R. 6' 2", 200 lbs.
2026(A+): .302/.359/.433, 20 2B, 2 3B, 6 HR, 20 SB, 8.2 BB%, 16.1 K%.
Giants are stockpiling legacy prospects. Kent is the son of recently inducted HOF'er Jeff. Profiles more at 2B defensively. Batted .417 in the 2024 College World Series. 3'rd round draft pick. High baseball IQ, line drive swing that produces contact but limits power.
Marty Gair RHP(Phillies). DOB: 7/17/2003. 6' 6", 230 lbs.
2026(A): 2-3, 4.91, 33 IP, 15.82 K/9, 5.73 BB/9, 6 Saves.
Big reliever with a bigger fastball that reaches 102 MPH. Just what the doctor ordered for a velocity starved bullpen. Can get a wild hair up his nose.
Marcelo Mayer IF(Red Sox). DOB: 12/12/2002. B-L, T-R. 6' 3", 188 lbs.
Anthony Molina RHP(Braves). DOB: 1/12/2002. 6' 1", 170 lbs.
