The Orioles have officially named Jake Arrieta as their final starter, according to Brittany Ghiroli of MLB.com. Arrieta, last year's Opening Day starter, had a fantastic spring, only allowing three earned runs in 17.1 innings. His only weakness this spring seemed to be control, as he allowed eight walks.
The 27-year-old beat out Brian Matusz and Jair Jurrjens for the final spot in the rotation. Matusz, who pitched well this spring up until his last start, has also made the team, but as a reliever. Jurrjens will likely start in Triple-A.
With both Arrieta and Matusz officially on the team, the Orioles' Rule 5 selection's, T.J. McFarland and Steve Johnson, futures are still up in the air, as Eduardo A. Encina of The Baltimore Sun points out in a tweet:
The fact that Tillman is on the DL means that McFarland will likely stay with the Orioles until April 6, at least, which is when Tillman will be reactivated. The Orioles must then make a decision on what to do with the lefty.
*update* - McFarland has made the team, while Steve Johnson has been placed on the DL.
Also according to Ghiroli, utility infielder Ryan Flaherty has made the team. The 26-year-old was the Orioles Rule 5 pick last season. Known for versatility, Flaherty seemed to be headed for Triple-A as spring ensued. However, Wilson Betemit's injury opened up an extra spot on the Orioles bench.
The Orioles will be down to 26 players by the end of the day, according to Roch Kubatko of MASN. The final roster spot will likely be between two players, Conor Jackson and Steve Pearce. Both players have had torrid springs, and both can play the outfield or first base.
*update* - Steve Pearce has made the Orioles final roster.
