Philadelphia sent All Star reliever Pat Neshek to Colorado on Wednesday night in exchange for three prospects. Let’s refresh:

Colorado gets
RHP Pat Neshek

Philadelphia gets
SS Jose Gomez
RHP J.D. Hammer
RHP Alejandro Requena

Gomez, a 20-year old infielder at Low-A Asheville, is the owner of a .316 career batting average and indeed scouts like his feel to hit. Gomez doesn’t get much out of his lower half and is a bit undersized, and thus very unlikely to hit for much power barring a mechanical change, but he has good hand-eye coordination, above average bat speed and a chance to be a plus hitter at peak.

An average runner with an average arm, Gomez lacks the high-end athleticism typically found at shortstop and is not a lock to stay there. He’s already seeing time at second and third base, two positions where Gomez will likely lack the power to profile every day should one of them become his long term defensive home. He projects as a bat-first utility player.

Hammer is a 23-year old relief prospect with a plus, running fastball that will touch 97. He was a 24th rounder out of Marshall last year and had struck out 47 hitters at Low-A before a late-June promotion to Hi-A Lancaster. Hammer’s arm is lightning quick and while he shows some feel for locating his fastball to his arm side with consistency (in part because it naturally runs that way), his command is currently below average. He also has a power slider (I’ve had scouts call it a slider and curveball, and the way its’ described makes it sound like a hard slurve, so I’ll call it a slider) that flashes average. He projects as a middle relief piece but could be more if a better secondary pitch can be coaxed out of that arm speed and, as a Colorado high schooler who then went to a college not typically associated with baseball, perhaps that’s coming late.

Finally, 20-year old Venezuelan Alejandro Requena is a pitchability who had posted a 2.85 ERA this season at Asheville. He sits in the 88-92 range with his fastball which he locates readily to both sides of the plate and he has a loopy, fringey curveball that he can lob in for strikes to get ahead of hitters or bury in the dirt when ahead in the count. He could max out as a backend starter but is more likely to fall in the starters 6-10 range teams typically need to dip into during the course of a season.

As far as FVs go, Gomez is a 40 for me, projecting as a utility man with a better bat than usually found there. That’s a 45 at peak with Gomez’s proximity from the Majors diluting the mark. The other two are, in FanGraphs prospect parlance, honorable mention prospects worth continued attention.

On Tuesday night, the Red Sox sent two prospects to San Francisco in exchange for infielder Eduardo Nunez. Those prospects were RHP Shaun Anderson and RHP Gregory Santos.

Anderson was a 2016 3rd rounder out of Florida, and another of the seemingly annual example of the Gators’ embarrassment of pitching riches, as Anderson has a starter’s repertoire but pitched out of their bullpen. He works an upper-80s cutter under the hands of left-handed hitters, has a low-80s slider with more loop that he runs away from righties, and he can turn over a fringe to average upper-70s curveball. He also has a formerly rarely used changeup that is now flashing average. The slider and cutter are effective when located properly, but all are fringe to average pitches purely on stuff.

Anderson’s fastball sits 92-94 and will touch 96. I’ve received mixed opinions about his strike-throwing ability, with some scouts thinking it’s suitable for continued projection as a starter while others found it lacking, citing frequent misfires resulting in fastballs and sliders left up and out of the strike zone. Single-A hitters have been willing to offer at these, upper-level hitters may not.

The range of outcomes scouts see for Anderson is relatively narrow. Some see him as a backend rotation piece, others as a reliever. Both place him in the 40 FV range.

Santos turns 18 in late August and was pitching in the DSL for the second straight year. He has yet to harness his terrific arm strength, sitting 92-96 with life. Santos joins a growing number of hard-throwing Latin American arms in the low levels of San Francisco’s farm system.

With Zack Wheeler joining the Mets’ small army of pitchers on the disabled list, the team will turn to 23-year-old Chris Flexen tonight against the Padres. Unless you’re a Mets fan with a deep interest in prospects, there’s a good chance this is your first time hearing Flexen’s name. I’ll admit that I was unaware of him until a couple of days ago when I came across his name while formatting KATOH’s most recent top-100 list.

But despite his obscurity, Flexen has undeniably earned this opportunity with the way he’s pitched this season. He started the year on the DL after having a bone chip removed from his right knee, but has been utterly dominant since returning. In three High-A starts, he pitched to a 2.81 xFIP with a 25% strikeout rate. He was even better in Double-A, spinning a 2.43 xFIP thanks to a 29% strikeout rate.

It’s been a long slog for Flexen, who was originally drafted by the Mets in the 12th round way back in 2012. After a couple of lackluster seasons in the lower levels, he underwent Tommy John Surgery in 2014. He pitched decently in 2016, his first full year after the surgery, but did so with a sub-17% strikeout rate. There was little reason to suspect he was on the verge of a breakout in 2017.

Eric Longenhagen included Flexen in his preseason Mets list, but only in the “Honorable Mention” section. He saw him as being worse than a 40 FV — the equivalent of a spot starter or middle reliever.

He sits 91-94, touching 96, with an average curveball and fringe change. He has a big, sturdy, inning-eating frame but has already had a surgery, and there are scouts who’d like to see if the fastball plays consistently at 96 out of the ‘pen . Others think he’s more of an up-and-down starter.

Eric provided an updated scouting snippet last month.

He has been 92-96, flashing an above-average slider and throwing all four of his pitches for strikes.

Because of scouts’ pessimism, there’s a sizable gap between Flexen’s stats-only KATOH forecast and KATOH+, which incorporates his (lack of) preseason prospect rank. The stats-only version projects him for 5.6 WAR over his first six years, which is good for 66th overall and 13th among pitchers. But that forecast drops to a meager 2.8 WAR once the scouting data is layered in. KATOH+ sees him as a near-certain fringe-player.

And since it looks noticeably different, I also made a stats-only graph. This one gives him a much more realistic chance of racking up more than 4 WAR.

To put some faces to Flexen’s statistical profile, let’s generate some statistical comps. I calculated a Mahalanobis distance between Flexen’s 2017 numbers and every historical season since 1991. In the table below, you’ll find the 10 most similar seasons, ranked from most to least similar. The WAR totals refer to each player’s first six seasons in the major leagues. Please note that the Mahalanobis analysis is separate from KATOH. KATOH relies on macro-level trends, rather than comps. The fates of a few statistically similar players shouldn’t be used to draw sweeping conclusions about a prospect’s future. For this reason, I recommend using a player’s KATOH forecast to assess his future potential. The comps give us some interesting names that sometimes feel spot-on, but they’re mostly just there for fun.

It’s tough to know what to make of Flexen. While his small-sample 2017 numbers have been exceptional, he’s never pitched anywhere near this well before, nor was he ever seen as much of a prospect. But then again, this might simply be an instance of Flexen finally being healthy for the first time in at least three years. I look forward to watching tonight to see how he fares against big-league hitters.
