The most recent addition to the competition, Shane Carle, 26, joins a cluster of arms who potentially could make up the Braves’ bullpen.

Here are five things to know about Carle:

When acquired: The Pirates traded Carle to the Braves on Jan. 17 for a player to be named later or cash. He had been designated for assignment by Colorado and Pittsburgh in the previous three weeks.

What to expect: Carle's fastball has been clocked as high as 95 mph. The right-hander uses his splitter as an out pitch. He's on the 40-man roster, but has options available, meaning he can be sent to Triple-A.

Summary of career: Carle made his major league debut last season, posting a 6.75 ERA in three September relief appearances for the Rockies. He had a 5.37 ERA over 36 games in Triple-A Albuquerque in 2017. Carle was a 10th-round pick by the Pirates in 2013 out of Long Beach State.

Career highlight: Carle's best season came in 2015 when he earned a 14-8 mark with a 3.68 ERA in 27 starts across the Rockies' Double-A and Triple-A affiliates. He first appeared in the majors April 14, 2017.

Something you didn't know about him: Carle is one of 48 Long Beach State products to crack the majors. In the past eight seasons, more Dirtbags have played in the majors than any other school. He's one of 15 active major leaguers from Long Beach State, a list that includes Evan Longoria, Troy Tulowitzki, Jason Vargas, Matt Duffy and Marco Estrada.
