Nationals vs Diamondbacks MLB Betting Preview
With the Diamondbacks already announcing a closed roof for Saturday, we have a stable run environment that is 8% above average.
We also know that hitter-friendly umpire Scott Barry is scheduled to be behind the plate.
That’s a 10% bump before we even get to the participants.
Zack Littell has posted an improved 3.62 FIP and .309 xwOBA over the last 30 days, with only two of his six barrels leaving the park, after allowing 13 home runs previously. He still has a 4.71 SIERA and 4.99 xFIP for the month with a 10.1 K-BB% and 31.7 GB%.
Non-FIP indicators ranging from a 4.17 Bot ERA to a 4.66 dERA suggest Eduardo Rodriguez’s 2.24 ERA is two runs ahead of his underlying performance.
I threw out the FIP because only five of his 17 barrels have left the ballpark. The 6.5 HR/FB is about as sustainable as his 84.4 LOB% or a .258 BABIP allowed (compared to his career mark of .304).
Congratulations on the 59 BotCmd and 108 Location+. It helps, but ERod is pitching on borrowed time.
You might think a predominantly left-handed Washington lineup would struggle against LHP, but its 116 wRC+ against them proves that’s not been the case. In addition, its projected lineup has a 122 wRC+ over the last 30 days.
Nationals vs Diamondbacks Pick, Betting Analysis
The Nationals brought in an entirely new regime this year, and their hard work is showing up in the batter's box.
Similar to Friday night, I believe we see some run scoring early in this game.
Pick: F5 Over 4.5 (Bet to 5)
