Dan Duquette is a roster-manipulating demon whose power cannot be contained. The latest Orioles move came before Tuesday's game against the Phillies, with the team adding infielder (who will probably be used as an outfielder) Chris Parmelee from Triple-A Norfolk. You might have expected one outfielder in would mean one outfielder out, but you're thinking inside the box. Duquette doesn't even know there is a box.
The actual move that the Orioles made to clear a spot on the roster was optioning starting pitcher Wei-Yin Chen to the High-A Frederick Keys. What the heck? And why Frederick? Also, to make room on the 40-man roster, Jonathan Schoop was transferred to the 60-day disabled list. He won't be ready in 60 days from when his rehab is complete, so there's no harm in this move. Eventually when they activate Schoop, they'll have to make a 40-man move. That is a future Duquette problem.
The O's beat crew indicated that Chen has been dealing with "general fatigue" so they'd like to throttle back his workload a bit. He will throw 3-4 innings for Frederick on Saturday and be eligible to return to the Orioles on June 26. Both Bowie and Frederick are home this weekend, so why one and not the other, I have no idea.
This reasoning of Chen's fatigue would hold up to scrutiny better if Chen had not just thrown eight innings last night. In a flight of fancy, one might imagine Duquette standing in eyesight of Chen's translator, lovingly cradling a baseball bat as he smiles and nods.
Thin logic aside, there are some benefits for the O's in the present. This way, Chen will avoid pitching against the Toronto Blue Jays this weekend. The Jays have an absurd .876 OPS against left-handed pitching as a team. That's over 100 points above the second place team in the AL. Instead they're going to possibly have Kevin Gausman make his first start of the year, if he looks good pitching in Frederick today.
Well, alright then. Good luck with all of that.
