Giants' Rafael Devers has been MLB's most disappointing player for 3 reasons

Those are some terrible numbers to begin the year, especially for someone making as much as Devers. And yet, the numbers get worse.

2. Devers' struggles on defense and on the bases

"If you factor in his defensive struggles and lack of speed, he has a negative 1 WAR," Nightengale writes.

According to his Baseball Savant page, aside from his brutal second-percentile batting run value, he has a 14th percentile base-running run value and a ninth percentile fielding run value.

This season at first base, he has two errors and negative three defensive runs saved. The move over to a new position hasn't gone well, and he's one of the worst fielders in the sport overall.

3. Trade and contract

Devers was acquired from the Red Sox for a haul, as the Giants sent Jose Bello, James Tibbs III, Kyle Harrison, and Jordan Hicks for Devers.

While Hicks didn't work out for the Red Sox, and Harrison and Tibbs were later traded by Boston, the cost was still fairly steep for the Giants to acquire Devers.

But the big reason why this cost to pick Devers up in a trade has made him MLB's biggest disappointment this season is that the Giants took on the remaining years of his $313.5 million deal through 2033.

Rafael Devers is one of MLB's biggest disappointments

Overall, there haven't been many players who can compare to Devers this season when it comes to being a disappointment for their teams.

He isn't out due to an injury, and he isn't simply just getting unlucky. Devers is struggling, and badly, in every phase of the game right now.

His presence at the plate has dipped, he's struggling in the field, and his baserunning isn't getting any better. Combined with his massive contract and the players the Giants gave up to get him, this is looking like a colossal mistake on the Giants' part.
