Dusty doesn't seem to be too concerned about Hunter's pitching load as the season goes on..always trying to squeeze as many pitches out of him each game. Rookies arm might not hold up.
Or perhaps Dusty is concerned about killing an already overtaxed bullpen. Meanwhile, Brown has been off for 11 days and has thrown 100 pitches once this whole season. And thanks to much of the early season having been a 6-man rotation, he's on pace for about 175 innings this season.
That's 2 outs we've given them this inning, though Chas's play was tougher than Pena's (who absolutely has to call that ball and go get it)
