BP wrote their analysis on the Woodman trade today and its behind a paywall so i'll have to paste the whole article.
Toronto Blue Jays acquired IF-R Aledmys Diaz from St. Louis Cardinals in exchange for OF-L J.B. Woodman. [12/1]
Usually the patented “Cardinals Devil Magic” makes a player much better over a longer term than Diaz, who was something of a disappointment almost immediately after coming over from Cuba. Sure, there were flashes of power and a hit tool, but nothing in his minor-league profile made him look like anything other than a bust and an organizational depth infielder who could eventually become a long-term fixture with the Triple-A Memphis Redbirds.
Instead, a chance opening covering for Ruben Tejada in 2016 turned into a feel-good, All-Star story and for a hot minute the Cardinals thought they had an elite shortstop of the future. All’s well that ends well, unless you’re sick and tired of St. Louis turning unheralded players into legitimate stars. But this breakout was short-lived, as you can tell by the fact that he was just traded for what appears to be a light-hitting, low-minors outfielder with a name like a lumberjack.
That 2016 power and production spike certainly looks much more like a fluke than a forecast. Last season, he started off as the Cardinals’ starting shortstop through the first three months, but a .260/.293/.396 line earned him a demotion with Greg Garcia and Paul Dejong waiting in the wings. He’d hit seven homers, which is perfectly acceptable so long as he adds value by reaching base and playing defense … neither of which he did well at all.
It takes a rare approach to fail to garner a .300 on-base percentage while hitting .260, so therein you have the definition of “empty batting average.” Not only did his True Average drop nearly .100 points, Diaz’s defense–which has always been considered questionable at shortstop–was just as bad, if not worse than his previous season. Our FRAA metric rated him 10 runs to the detriment of his team, and the eye test certainly didn’t do him any favors either.
After he was shipped off to Memphis, Dejong came up and had a breakout not dissimilar to Diaz’s own during the previous season, so there was no hope of the plucky Cuban coming back up and fighting for his old job. He became superfluous. Of course, superfluous in St. Louis isn’t exactly superfluous a few hundred miles north. The Blue Jays have to deal with two injury risks up the middle in Troy Tulowitzki and Devon Travis, and any non-Ryan Goins depth would be greatly appreciated.
Betting on Diaz as a reserve middle infielder isn’t a bad idea at such a low cost, because if he somehow finds a bit more of his 2016 stroke, he could be a suitable bat-first backup and might be a little more defensively apt at a different infield spot. I personally don’t have a lot of hope for an All-Star renaissance, or even a return to relevance, but this deal probably benefits all parties involved. The Cardinals slough off a mild, but unnecessary contract, the Blue Jays take a flyer on a potential reserve, and Diaz gets a clearer path to playing time.
On a note unrelated to Diaz’s on-field performance, please check out this Twitter thread from John Rabe, who reminds us of baseball’s power to provide light and joy as a respite from the most challenging of circumstances. —Bryan Grosnick

St. Louis Cardinals acquired OF-L J.B. Woodman from Toronto Blue Jays in exchange for IF-R Aledmys Diaz. [12/1]
Woodman struggled this season in the Single-A Midwest League and often looked overmatched while hitting .240/.320/.378 in 96 games at age 22. The former second-round draft pick out of the University of Mississippi showed a poor approach at the plate, getting overaggressive, expanding the zone frequently, and striking out a ton on the way to a 157/40 K/BB ratio.
He flashed decent speed and athleticism on the defensive side of the ball while playing all three outfield spots, but his reads were inconsistent and as a whole he looked raw in center field, with a full-time shift to a corner a distinct possibility. —Emmett Rosenbaum
