MLB Winter Meeting Stock Update

It's mid-December, which means we're roughly two months out from pitchers and catchers reporting.

But the dust from the Winter Meetings is just beginning to settle. We saw the Red Sox go all in to land Chris Sale, the Rockies surprise many by signing Ian Desmond (and likely forcing him into another position change), and the White Sox revamp their farm system while seemingly punting the 2017 campaign. As one would imagine, a change of scenery can impact a player's performance, both positively and negatively. With that in mind, here is a listing of how some players were affected by the transactions during the Winter Meetings.

STOCK RISING

Mark Melancon - RP (New Team: Giants / Old Team: Pirates/Nationals)

Melancon is one of baseball's elite closers, and this move on paper seems like it could make him even more dominant. AT&T Park is one of the most pitcher-friendly parks in all of baseball thanks to how significantly home runs are depressed, which can only help the veteran reliever even if he is already a groundball pitcher. Along with that, Melancon has excellent numbers against the other members of the NL West, with his ERA sitting at 2.00 or lower against all four other teams in the division and only one of the other four teams holding a batting average above .200 against him over the past three years.

Steve Pearce - 1B/2B/OF/DH (New Team: Blue Jays / Old Team: Rays/Orioles)

The trade deadline deal from Tampa Bay to Baltimore could've been helpful to Pearce, but given his limited opportunities and the fact that Baltimore typically plays better to lefties, his tenure in Maryland wasn't as good as expected. This change of scenery could be the spark that Pearce needs to get back to the way he was performing in the first half with Tampa Bay. With the left-field line only sitting 328 feet away from home plate and a semi-regular role seeming to be in the cards for the 33-year-old, things are looking up for him.

Yoan Moncada - 2B/3B (New Team: White Sox / Old Team: Red Sox)

Now that Moncada's in a White Sox organization that seems to be in the midst of a full-fledged fire sale, baseball's top prospect seems to be primed for plenty of action in the big leagues. He may begin the year at Triple-A Charlotte to work on cutting some of the strikeouts out of his game, but his immense talent will likely land him on the south side in no time.

STOCK FALLING

Taijuan Walker - SP (New Team: Diamondbacks / Old Team: Mariners)

A lot of metrics work in Walker's favor, and given his age, he's a potential breakout candidate. However, one stat that really stands out is his home-run rate. Walker gave up 15 home runs at home last season. That equates to a 1.6 HR/9 in the normally pitcher-friendly confines of Safeco Field. There's a lot going for the 24-year-old (including a new pitch in his arsenal), but his home run woes could get even worse with a move to the hitter's haven known as Chase Field.

Jean Segura - 2B/SS (New Team: Mariners / Old Team: Diamondbacks)

Segura was another major piece in the trade that sent Taijuan Walker to the Diamondbacks, but like the aforementioned hurler, Segura's value seems to have decreased a bit with the change in scenery. Any player's stats will naturally inflate a bit during some time at Chase Field, but now the young middle infielder will have to step in and replicate that production in a much more pitcher-friendly environment. His home-road splits seem to suggest that playing half his games in Phoenix (and a good chunk at Coors Field) assisted in his breakout campaign (.325 home BA vs. .312 road BA, .529 home SLG vs. .468 road SLG), meaning 2017 could be a tough year for Segura.

Tyler Thornburg - RP (New Team: Red Sox / Old Team: Brewers)
After several seasons in limbo between the rotation and the bullpen with the Brewers, Thornburg finally became a full-time reliever and found considerably more success. He actually acted as Milwaukee's closer for a bit at the end of the 2016 campaign as well, amassing 13 saves to go with his 20 holds, 12.1 K/9, and 2.15 ERA. However, the right-hander now has to pitch out of a bullpen of a legitimate contender rather than a cellar-dweller. To pair with that, he won't even have the closer's job upon his arrival, with incumbent Craig Kimbrel keeping the role on lockdown. Thornburg will have to garner value based on holds and strikeouts alone, and with the added pressure of being in Boston, it'll be tough to carve out as much value as he did in 2016.
