"I'd like clarity a couple weeks ago, but it doesn't look like it's going to happen," Baker said. "It'll probably go down to the end. You always want somebody to step up definitely. It makes our decision easier."
Worley is perhaps the most intriguing candidate, considering he could fill the role most similar to right-hander Yusmeiro Petit, who was what Baker called his utility pitcher last season because of his versatility to pitch in so many different spots. Worley served in a similar capacity for the Orioles, starting four games, finishing 13 and pitching in middle relief in outings ranging from one batter to seven innings.
"I've seen him do everything," Baker said prior to the game. "He has a very resilient arm. He can go long. He can start. He can go short. He's a guy that could throw almost every day. But we've got some other guys here that are vying for that position that are very similar in Matt Albers and Guthrie."
However, it is unclear if there are enough open spots in the bullpen. Assuming they carry seven relievers (Shawn Kelley, Blake Treinen, Joe Blanton, Oliver Perez and Sammy Solis are all locks), it leaves two spots open. That means the Nats would have to either send someone like Koda Glover -- who has been one of their most impressive relievers this spring -- to start the season in the Minors or part ways with Enny Romero, who has been throwing 98-99 mph consistently. Baker would not commit to definitely keeping a long reliever, but highlighted the importance of a pitcher to fill that role even with the rotation representing a strength.
Still, it leaves some uncertainty for pitchers like Worley.
"Early on in camp, yeah, it was a good opportunity here and I think it still is," Worley said. "They went out and they signed some more guys and some of them got spots, so it's tough not to think about it. But at the same time, this is pretty much a trial for everybody to see how things go.
"I want to be here. That's why I signed here. We'll see what they think of me by the end of camp."
