Good morning, cla s. Please take your seats. It is I, your totally legitimate and credible profe sor, Dr. Joe Rivera.

When we last met, we discu sed the and their potential fire sale. I hope you took notes, because today's le son is something of a recurring one.

Jerry Dipoto has a vivid imagination when it comes to baseball rosters. His constant re-imagining of the Seattle Mariners over the past four seasons has earned him the title of Guru of Tradeology, something that you certainly cannot learn at any online university and is a totally real thing.

With reports surfacing that the Mariners are having a fire sale, Dipoto is going to po sibly, maybe, potentially finally build a roster, present or future, in his image. Even though the Mariners are scuffling, they have plenty of players who could make an impact on playoff-hungry teams.

Using a highly complex formula which is about as confusing as Dipoto's roster re-imaginings, so good luck trying to figure that out that CeeDee Lamb Jerseys includes production, contract, position, depth of position in the farm system, durability, trade market and personality, we've come up with a player's tradeability grade.

Take your seats, take out your notebooks and pay attention: Cla s is in se sion. Today's le son, the Seattle Mariners. This is Tradeology 101. Do not @ me.

Mitch Haniger

Position:Outfielder

Contract:Arbitration eligible through 2022; free agent after 2022

Tradeability:A-

While it seemed pretty pie-in-the-sky that Haniger would be on the move before the season, if there's truth to the reports that the Mariners are in full-blown fire-sale mode, Haniger is one of the most intriguing trade options on the Mariners.

Haniger, 28, has been one of the more underrated players in baseball over the past two seasons. While his power numbers have dipped a bit in 2019, he's still been worth 1.5 bWAR through 59 games, so he's on pace for a great season. He's also coming off a 6.1 bWAR season in 2018 (157 games),his best season to date.

Haniger won't hit free agency until after the 2022 season, so his prime years are under team control. He only loses points because he doesn't have a long history of production: His 2018 season was the first he's played a full year, while his 2017 was injury riddled.

Still, Haniger is a plus defender and a plus bat when he's right, so should a team needa starting caliber bat with good power and a controllable contract, this is your guy.

Kyle Seager

Position:Third base

Contract:Two years, $38 million after 2019; $15 Ceedee Lamb T Shirts million team option for 2022

Tradeability:C+

Corey's brother has been a solid player for Seattle for eight seasons, playing good defense and being a serviceable bat as well. In his eight Seattle seasons entering 2019, Seager was worth 28 wins per Baseball Reference, with a .258/.324/.440 slash line to go with it. He's got 20-plus home run power and plays a serviceable third base, perfect for a team looking for a good midseason reinforcement to anchor a lineup.

The key to moving Seager would be to eat money on his contract: He's making $19.5 million in 2020 and $18.5 million in 2021, numbers that don't nece sarily agree with the player he's been the past two seasons (2.7 bWAR in 2017 followed by 0.8 bWAR in 2018).

Perhaps the biggest obstacle in trading Seager is the team option: Should Seager be traded, the team option for 2022 transitions into a $15 million player option, a number he would DeMarcus Lawrence Jerseys most definitely pick up.

Trading Seager for prospects is likely something the Mariners will explore, but they'll also have to deal with the lack of organizational depth at third base: As of June 3, the Mariners only had one third baseman in MLB Pipeline's top 30 prospects, Joe Rizzo, who has yet to play above High-A ball.

Domingo Santana

Position:Outfield

Contract:Arbitration eligible through 2022; free agent after 2022

Tradeability:B-

With regular playing time, Santana got off to a hot start, hitting .292 with an .842 OPS in March/April with six home runs in 31 games. In May, he took a step back he hit just .237 with a .749 OPS and 34 strikeouts in 93 at-bats.

Santana, a righty, is very good against right-handed pitching, not as much so against lefty pitching, with an OPS 80 points lower vs. lefties in 2019. This is odd for Santana, who showcases roughly the same OPS vs. both lefties and righties in his career (.795 vs. righties opposed to .815 vs. lefties).

Those numbers aside, Santana has a 112career OPS+with 30-homer power and a 3-WAR ceiling in a full season. If a team is looking for more pop out of right field, Santana is the guy, but when looking at teams that could be in the playoff hunt, outfields are loaded, so it's hard to see where Santana goes if he's traded after a short stay in Dallas Cowboys Kids Jersey the Emerald City.

Edwin Encarnacion

Position:First base/DH

Contract:$20 million team option for 2020; free agent after 2020

Tradeability:B-

Again, if money isn't an i sue, it wouldn't be a surprise to see Encarnacion on the move as the trade deadline nears. He's on pace for a better season in 2019 than 2018 by WAR and is also likely to notchmore than 30 longballs this season.

Encarnacion is a perfect DH/backup first base option on the trade market, should a team be jonesing for some power in the lineup. He has a team option for 2020, so a receiving team would have to deal with the option or buyout ($5 million) if they want to move on from Encarnacion and his parrot.
