The Phillies were busy on Trade Deadline day. In two deals, the Phillies added two relievers, bringing in Giants closer Caleb Kilian, plus Mets reliever Brooks Raley. But the big prize was Luis Arraez, who will head back to the NL East to continue a fantastic 2026 season.
The Phillies’ Return
- 2B Luis Arraez (.324/.360/.441, four HR & 34 XBH over 105 GP)
- RP Caleb Kilian (4.26 ERA, 53 over 44 IP)
- RP Brooks Raley (1.96 ERA, 40 K over 41.1 IP)
Luis Arraez re-invented himself in 2026.
Arraez signed a one-year deal with the Giants late in the offseason, sitting on the market despite being a multi-time batting champion. However, this was a renaissance season in one way more than others, as Arraez — largely a below-average defender at first & second — became one of the best defensive second basemen in terms of Outs Above Average.
Aside from that, the bat was very good. His 4.5% K% was the lowest in the Majors this season, as Arraez’s well-known plus-plus contact tool and swing resulted in a lot of base hits, just like he’s done throughout his MLB career.
The Phillies also picked up two relievers, one of whom was now-former Met Brooks Raley. A difficult-to-hit left-hander who doesn’t throw hard but can get in on both left-handed hitters and right-handed bats, too. Opposing batters have recorded a measly .267 wOBA on him this season.
The other piece to this deal is Caleb Kilian. Mid-90s two-seam & four-seamer that ran up to 100 MPH this season, plus a curveball and a slider. Lots of swing-and-miss from Kilian’s curveball and slider this season.
The Mets’ Return
- OF John Spikerman (.252/.423/.330, no HR & six XBH over 32 GP (A & A+))
- P Luke Gabrysh (5.14 ERA, 89 K over 68.1 IP (A+))
John Spikerman was a third-round pick out of Oklahoma after he hit .367 as a junior with the Sooners. He flashed a ton of tools last year in A-ball, as he stole 30 bases in 62 contests. And this year, the outfielder picked up 18 over 32 games.
Lots of walks from Spikerman over his pro career. The only problem has been health. Since he was drafted in 2024, he’s only played in 111 games as a pro.
The other piece to this deal for the Mets is starting pitcher prospect Luke Gabrysh. A 15th-round pick by the Phillies two years ago out of St. Joseph’s, the 23-year-old averaged about a walk every other inning but put up a lot of strikeouts with High-A Jersey Shore this season.
Mid-90s fastball, two-seam & four-seamer for Gabrysh, plus a high-80s cutter, a slider, and he also made use of a curveball & changeup in A-ball.
The Giants’ Return
- SP Ramon Marquez (1.68 ERA, 93 K over 59 IP (A & A+))
- RP Marty Gair (4.50 ERA, 66 K over 36 IP (A & A+))
The Phillies sent two of their most valuable A-ball pitcher to the Giants, with the headliner being Ramon Marquez.
Marquez blew through A-ball after a dominant start to the year with Low-A Clearwater. And in six starts with High-A Jersey Shore, the 20-year-old right-hander struck out 46 batters over 30 innings, along with a sub-2.00 ERA.
As we’ve noted multiple times this year, Marquez is a swing-and-miss machine. Marquez flirted with a swing-and-miss rate of about 50% in his first weeks with High-A, obscene numbers even at that level. And it’s a fairly simple arsenal: a hard sinker that ran as high as 98 MPH, a biting cutter that had a 50% Whiff% in Clearwater, plus his ace pitch, a changeup.
That changeup had an overall Whiff% of 66% in Low-A. Low-80s offering, separated by about 10-15 MPH off the sinker.
Gair, meanwhile, is an R&D department’s dream. As we noted both last year & this year, blistering fastball that can touch triple digits and was very difficult for opposing hitters to pick up.
Analysis
First off, the Giants did incredibly well here.
The Giants turned four months of Luis Arraez, plus Caleb Kilian, into one of the best pitching prospects in the Minors with Ramon Marquez. It was a high price to pay for the Phillies, although the club didn’t have to part with Gage Wood. Still, it’s a desperate time where all the National League teams are trying to keep up with one another.
And realistically, the Phillies were able to take care of multiple needs in one swoop. Two relievers to shake up a bullpen that doesn’t have Brad Keller, and saw several others take steps back. Now, a good matchup lefty, plus Kilian, make the road to getting to Jhoan Duran much easier.
Another element is how this will work positionally. For now, it appears that Bryce Harper will go back to right field, a position that he hasn’t fielded in years. Given how much Arraez has improved defensively, it would make a high degree of sense to keep him at second, meaning Bryson Stott goes to third and Alec Bohm to first.
Months after the rumors around Bo Bichette, it looks like the Stott move finally happens.
The Mets, meanwhile, didn’t get the kind of value that the club did for A.J. Minter. However, it is two more prospects with upside.
