They are a young team, young teams are inconsistent teams.
Phillies shouldn't be in 1st place, they won 66 games last year (though close to .500 the second half), Crawford injured, Kingery struggling, Altherr sent down, Pivetta struggling, Arrieta not the #1 starter he was two years ago, Santana hitting .210.
They're doing it a bit with "smoke and mirrors" (winning more than expected in 1 run games), some young players stepping up.
The most important thing, like the Flyers, is to enjoy it but remember they're still rebuilding and not fall into "win now" syndrome.
Fortunately, Klentak is as patient as Hextall, one reason Kilome was traded was room on the 40 man roster, a number of other young pitchers (De Los Santos, Suarez, Romero, Medina, and of course Sixto) have passed him as he continues to struggle with command. So he traded an asset he might have had to expose to the Rule 5 draft.
