Just have to bridge until Marsh returns.
Rojas is looking more and more like a player who's going to be a fixture in CF, he's got the most range of a Phillie CF since Gary Maddox. His defense is so good it allows the team to be patient with him as a hitter, and so far Rojas looks like he belongs in the Show, worked a nice walk, has a little pop, he hasn't looked overmatched.
Rojas in CF and Marsh in LF makes an improved Castellanos tolerable in RF.
Even Dombrowski concedes that OF defense can compensate for lesser offense, and so far, Marsh/Pache/Rojas really haven't cost much offensively, the problem has been Harrison/Caves/Hall. Schwarber is going to be the DH going forward, and I think Harper is going to be the 1B.
As I've pointed out, when pitching is at a premium, defense is more valuable b/c those extra outs reduce the pitch load on your better pitchers, both reducing injuries from overuse and having to employ inferior pitchers in key situations.
