Imagine for a moment that Mark Trumbo didn't have two years and $26 million left on his contract. If you had to pick between Trumbo and Alvarez as to who'd have the better numbers as the O's DH in 2018, who would you choose? I asked this very question in a Twitter poll on Sunday. You may be surprised with the results:
It's not so crazy, though! The two players' Steamer and ZiPS projections are close: 105 and 101 wRC+, respectively, for Trumbo, and 112 (!) and 98 for Alvarez. Trumbo is 32 years old and has a career 106 wRC+; Alvarez is 31 and has a career 107 wRC+.Who has the better numbers with a full year at DH?— Matt Kremnitzer (@mattkremnitzer) February 25, 2018
As Jon and others have discussed numerous times on this site, the knock on Trumbo is that he's a bad outfielder who struggles when he's forced to DH. He could play first base on another team, but the Orioles have Chris Davis locked into that position. That means Trumbo is likely to see the bulk of his at-bats as a DH. In his playing career, that hasn't gone well:
Trumbo career DH: 88 wRC+
Trumbo career non-DH: 112 wRC+
Have things been better recently? No. Trumbo has been with the Orioles since 2016, and in his two seasons in Baltimore, he has a 81 wRC+ as a DH (713 PA) and a 133 wRC+ as a position player (554 PA). (For reference, the MLB average DH had a wRC+ of 94 last year.)
For Alvarez, the opposite has been the case. He's performed much better as a DH:
Alvarez career DH: 124 wRC+
Alvarez career non-DH: 107 wRC+
Most of Alvarez's DH work has come with the Orioles, and his DH numbers look even better when counting just the 2016 and 2017 seasons: 129 wRC+ (360 PA). In his 31 non-DH plate appearances, Alvarez has a 73 wRC+.
Career wise, Trumbo has more than 1,000 plate appearances as a DH while Alvarez has just over 400, so the case is stronger that Trumbo hits worse as a DH than it is that Alvarez is much better as a DH. Also, of Alvarez's 410 plate appearances with the O's, 365 have come against right-handed pitching, while just 45 have been against lefties. In his career, Alvarez has a 117 wRC+ against right-handed pitching but a wRC+ of only 70 against southpaws. Trumbo, meanwhile, has not been used as a platoon bat.
So what matters more: Trumbo's shortcomings as a DH, or Alvarez's struggles against left-handed pitching? Probably Trumbo's DH issues, especially since, if Alvarez were the main DH option, the O's could opt to use a right-handed hitter at DH when the O's face a lefty. (That could give some regulars a rest from playing the field that day.) It's tough to get around carrying a DH who's not going to hit as well.
Back to reality. Trumbo does indeed have $26 million left on his deal, and if another team wanted to take him and his salary off the O's hands, it maybe would have happened already. (And it looks less likely now that someone like Logan Morrison had to settle for a one-year, $6.5 million deal with a 2019 vesting option.) Still, if the O's could find a taker for Trumbo's remaining salary (or even, improbably, eat some of it) and then use Alvarez as the main DH, would you do it?
