In a lineup with Harper or Machado Cesar has the 3rd highest 2018 OBP (Harper .393, McCutchen .368, Machado .367, Hernandez .356, Hoskins .354).
If you build the lineup using just OBP then sure, but Hernandez has the lowest SLG of that group by a significant margin and while hes fast hes not exactly a massive base-stealing threat.
Despite his injury his raw 2018 numbers aren't that far below his career levels either (.356 vs .357 for OBP and .362 vs .372 for SLG).
OdĂșbel had the lowest OBP (.310) of any of our 2019 projected lineup with or without Harper/Machado, though his career (.336) is more reasonably middle of the pack and is actually almost identical to Mannys career (.335).
I realise this is very basic stuff but I don't think Cesar deserves a place near the top of the order on merit assuming we see one of the two big bats come in.
I would suggest Harper, Machado, Hoskins, McCutchen, Realmuto and Segura are all better hitters than both OdĂșbel and Cesar. I love OBP but it doesn't tell us much on its own. Someone who walks 35% of the time but never gets on base any other time isn't more valuable than someone who hits a HR 10% of the time. At least not in a vacuum.
I wanted to check this so took a look at Baseball References Projected Plate Appearances, Total Bases, Walks, Hit By Pitches and Stolen Bases-Caught Stealing for each player for 2019 and Cesar ranks 10th in Total bases + Walks + HBP + SB -CS per Plate Appearance behind only Maikel Franco. Using this very crude metric to build an "ideal" lineup gives us the following:
Harper .583 Base Per Plate Appearance
McCutchen .578
Hoskins .574
Machado .563
Realmuto .501
(Williams.485 if no Harper - this surprised me)
Segura .480
Herrea .479
Hernandez .471
(Franco .469 if no Machado)
If we use this metric and assume BRefs projections are accurate and that everyone gets the exact same number of PAss then the best offensive lineup possible is unsurprisingly the one with both Harper and Machado, followed by Harper and Franco marginally ahead of Manny and Williams. Science. Using this clearly brilliant metric the gap between them is so marginal that defence should be used to prioritise who to sign.
So we should sign Manny. I've come full circle.
Edit: In case it's not obvious I'm currently bored at work and killing time.
