9) David Robertson - New York Mets
The Mets signed David Robertson to a one-year $10 million dollar deal this offseason. Robertson was a player I desperately wanted the Mets to trade for at the trade deadline but they opted to allow the division rival Phillies to land him.
Robertson posted a 2.40 ERA in 58 games splitting time with the Cubs and Phillies. He served as the closer in Chicago before being used in all kinds of situations for the Phillies. Robertson is a guy the Mets can use in the sixth, seventh, eighth, or ninth inning and expect success. He's been a very good reliever throughout his 14-year career and even with him being 37, I expect nothing less from him in 2023.
Robertson also comes with experience pitching in the postseason and in New York. He won the World Series with the Yankees in 2009 and can hopefully do the same with the Mets in 2023.
8) Brooks Raley - New York Mets
One of the weaknesses the Mets had last season was having no reliable left-hander to go to. Chasen Shreve was DFA'd in July and Joely Rodriguez was just never reliable enough to take a hold of that role.
The Mets traded for Brooks Raley to be the lefty to get hitters like Bryce Harper, Kyle Schwarber, and Matt Olson out in a big spot. If he repeats the season he had with the Rays, the Mets will be in very good shape.
Raley posted a 2.68 ERA in 60 appearances for the Rays. He had a 2.74 FIP and struck out 10.2 batters per nine while walking just 2.5. He showed an ability to get both lefties and righties out which is crucial for the three batter rule.
The Mets bullpen is better and it's mainly because of the upgrade Raley will be over Rodriguez and Shreve.
