He won’t start that many games this year. He only started 131 in 2017, easily his most productive season offensively in years. 126 starts in 2016, 154 in 2015, 118 in 2014, his first year as a non catcher. IMO 125 starts in 2019 is extremely unlikely. Even if he doesn’t land on the DL, which is pretty likely to happen given his age and injury history. 110 is a more realistic number I think. And therein lies the problem. You have a wasted roster spot for 50 games, almost 1/3 of the season. Some said he can pinch hit. Sure. The Twins have used a pinch hitter in less than half their games this year. And how many of those were “throw away” at bats in blow outs? The kind Mauer wouldn’t get anyway. Point being, the days of having a dangerous pinch hitter lurking are gone in the AL.
