It is too early to do any realistic predictions on what is going on in FO/Vogts minds but
CF - It is Thomas to lose (no RF option for him at this point). On off days, it has just been Freeman, Schneemann and even Halpin
RF - They are giving Noel and Brennan every chance to win the spot but Brennan 0-7 and Noel 2-9 w 5 ks isn't helping. Thus, why Rodriquez is getting some time (even if just LF).
SS - Rocchio is staying there (no 2nd switch). Like CF there has been Schneemann (twice), Freeman and now Arias fill ins but no consistency yet to say go win it. With Schneemann going 0-6 (so far), it was time to see Arias there.
C - It is Bo or bust at this point (of course). Huff only given mop-up time and we aren't going Nunez and Hedges.
2nd - Brito is missing the 2nd game in a row. Will be interesting to see the lineup tomorrow because its Arias turn at 2nd (will be his back-2-back with SS duty today but could be 3rd day that Brito misses if Rocchio is SS and Ramirez 3rd). His 0-7 start w 3 ks is maybe pressing (so time off).
On starters - they are splitting Cantillo and Cecconi this week (combined start last week). It makes some sense as they stretch out and need to get our primary relievers in (who they were holding back). At some point, Bibee needs to be slipped in but he may just show up in minor league games and let the others show their stuff against mlb talent for the 4th/5th starter battle.
