Joey Votto is 40 years old, and as most senior players tend to do, has fought injuries the last two seasons while putting up basically below replacement-level numbers. The batting average, and with that his once-coveted OBP, has plummeted. Yes, he's a former MVP and multiple time All Star. But he hasn't been good in a couple years.
If there is one positive, its that his power numbers have managed to stay relatively decent. He's always hit well at Am Fam Field, which tends to boost lefty power hitters. But even with those factors, we aren't likely looking at much upside, unless some kind of crazy career resurgence comes out of nowhere. And that typically doesn't happen with 40-year-old power hitters.
