A look and my personal take on the effectiveness of said acquisitions.
Luis Robert Jr. has appeared in 24 of 40 games & is on the IL with no time table for his return. Not making the bounce back hoped for.
Jorge Polanco has appeared in 14 of 40 games & is still on the IL with no time table for his return. Small sample size, but not providing much when on the field.
Mike Tauchman has yet to appear in a game following a spring training injury to his left knee. Currently recuperating from surgery with hopes of reinstating baseball activities in late June or early July.
Bo Bichette has at least been healthy. Like most of the Mets line up, he is not performing to level anticipated at his signing. Looks like a very expensive 1 year rental.
Devin Williams has been available. Poor start, but is showing signs of life of late. Has allowed only 1 hit & 0 walks with 6 Ks and most importantly no runs allowed over his last 5 outings (4.2 innings).
Luke Weaver has remained healthy. Overall, his numbers haven't been too bad. He had a few rough outings, but overall his numbers haven't been too bad.
Marcus Semien - Playing solid defense at second base, but his best days are far in the past offensively. Like the majority of the roster he is hitting for a low average with low OBP and SLG.
Luis Garcia - Made 6 appearances too many (6.1 IP w/ 7.11 ERA & 2.053 WHIP) before release. Pitching even worse for the Twins.
Freddy Peralta - Has pitched well enough (43.1 IP w/ 3.12 ERA & 1.200 WHIP), but only averaging 4.2 innings per start. Not a true ace, but a solid #2 starter.
Tobias Myers - Has been a pleasant surprise. Had rough outing recently against the Rockies, but overall he has pitched well (24.2 IP w/ 3.28 ERA & 1.014 WHIP).
Joey Gerber - Made 1 appearance, pitched 2 effective innings, then left with a blister. Pitching in AAA Syracuse.
Carl Edwards Jr. - Made 2 appearances and in a small sample size pitched better than most of the Mets staff (2 games, 6 IP, 1.50 ERA & 1.167 WHIP). Elected to become a minor league FA when the Mets failed to appreciate his work.
Vidal Brujan - Getting what we should have expected. He has never been a good hitter and shows no evidence that he is now.
There was too much offense that left (via FA & trades) and far too little brought in to replace it, so it shouldn't be a surprise that the Mets are dead last in MLB in OBP, SLG, OPS, and next to last in runs. Which of course leads to last in wins.
In the end, you are judged on your job performance based on results and this year the results are very poor.
