Nitpic, but Moran put 3 runners on, not two. He pitched to 3 hitters: BB, BB, RBI double.
Pagan came in with no outs, a run in, and runners on 2nd and 3rd. He gave up an RBI ground out, then a 2 run HR. Then finished out the inning.
He wasn't good, but only 1 runner, and 1 run, were his fault.
Three of those 4 runs were on Moran, and properly charged to his pitching line.
You simply cannot come into a game up 4 and walk the first 2 hitters. Inexcusable.
