Unless ESPN's stats are dated, I see Acuña leading in HR (21 to 15), trailing in Average (.291 to .288), and tied in RBI (45). The problem is that Soto started off hot to create a significant lead both in stats and in perception while RA started slower. It's now up to RA to pass Soto which he's entirely capable of doing. As I said, there's a long way to go but I believe if the vote were taken today, Soto would win. Fortunately, the vote isn't being taken today.
Acuna at 288 and Soto ended the day at 287. Often times in these awards it's what have you done for me lately and Acuna mashing right now is in everyones mind.
