Another guy who makes the season fun to watch, who I know everyone appreciates (yet I feel kind of gets forgotten when you have Judge on pace for 10 WAR, Carpenter blowing up and then getting hurt, Torres and Donaldson being kind of frustrating, Stanton doing his usual sometimes awesome, sometimes seeming like he's never seen a breaking ball ever, sometimes hurt thing) is LeMahieu.
Currently 6th in ALL of MLB in position player bWAR. WAR by year with his salary:
2019: 5.6 bWAR, $12M
2020: 3.0 bWAR in 1/3 of a season (tied for 4th in all of MLB), $4M prorated I think
2021: 1.5 bWAR, $15M, not great but still useful considering his defensive flexibility
2022: 4.6 bWAR and counting, $15M
That's insane value, 3 all-star-level years out of 4. Assuming he doesn't age terribly (he's a weirdly big guy but he has great contact skills and doesn't rely on speed so who knows), that's still likely a very good contract going forward.
It's funny to remember how much the Yankees were kind of pilloried on his signing. To be fair, it was partially because they cheaped out on Machado, but it still worked out.
