Adrian Beltre missed five games in mid-June (14th through 18th). He was hitting .244/.279/.361 at the time, certainly not the production we all expected.
His line currently sits at .264/.305/.403, so yeah, he’s done some good things since his mini-DL stint — by my calculations, he’s hitting .360/.458/.480 since missing those games. Expanding the sample a bit, he hit .321/.391/.444 in June.
In any event, I’m not concerned.
