2017 runs scored per game = 4.28
2018 runs scored per game = 5.06 (proj.)
They have us at 5th in the league in runs per game. Last year we were tied for 25th. That would be one hell of a turnaround. Taking the 1042 (!!!) PA that Goins/Barney/Refsnyder/Coghlan/Urena got last year and giving them to Diaz/Solarte (or, fingers crossed, some to Travis/Tulo) should help a lot. I'd also love to see the 237 Maile/Montero PA's given to someone half decent, but there's only Lucroy, Ruiz, and Soto out there now.
2017 runs allowed per game = 4.84
2018 runs allowed per game = 4.73 (proj.)
A slight improvement in run prevention is a lot easier to see than the huge offensive one IMO. If Biagini goes to the pen and replicates some of his success, Garcia is semi-decent, and Sanchez stays moderately healthy, that projection should hold true. Not to mention no Bautista bleeding runs on the defensive side of the ball.
Of course, Ohtani's 3.6 WAR projection (3.0 SP + 0.6 DH) could look pretty silly and blast us out of contention in a hurry. Still, there's lots of reason to be optimistic for this season despite the pure s*** that was 2017.
