I am minutes old in my exposure to the mysterious world of SABRmetric advanced stats. I do NOT want to get deeply into it...but i do want a SIMPLE upgade of the usual statistics, that i do know have many correctable inadequacies...
Pitching: ERA
Batting (aka. offense): Batting Average (even if supplemented with OBA, SLG)
Fielding (ie. non-pitching aspects of defense): Fielding Average
I want a few stats I can look at for an upcoming game that do a better job. I intend to apply the Pitching stat to the starters and for the bullpens involved (sometimes this'll suggest FF vs FG)...and apply the stats for each of the Batting and Fielding components to each team. Possibly down the road, start considering "home" and "away" versions of each of the three stats, etc...
I know that eventually a "toolkit" of stats will develop for each game component...but what I want to know...if u could only put one tool into each of the three trays which would it be (a "starter kit" if you will...cuz i know more may be added later).

I just spent some time at Fangraphs...here's what my quest for a single best summary stat for each of the major aspects of the game has come up with.
Pitching: SIERA
Batting (aka. offense): wRC+
Fielding (ie. non-pitching aspects of defense): either UZR or DRS

if ur an experienced SABRmetrician, i'd LOVE to hear from you, but remember my purpose is not to become a fellow devotee...i simply want to know which single statistic per aspect (Pitching/Batting/Fielding) would you keep if you "gun to the head" had to forego all others.
