PITTSBURGH — The Pittsburgh Pirates aren't waiting for the trade deadline to make moves, as they've already added to their roster.The Pirates announced that they traded catcher Joey Bart to the Atlanta Braves in exchange for right-handed relief pitcher Hunter Stratton, who the Braves had previously designated for assignment on June 17. Stratton will report to Triple-A Indianapolis. Bart joined the Pirates two years ago on April 4, 2024, in a trade with the San Francisco Giants, that sent right-handed pitcher Hunter Strickland the other way.Stratton previously pitched three seasons for the Pirates and will surely get a shot to join the bullpen at some point this season. Why the Pirates Traded Joey BartBart hadn't played for the Pirates since early May, going on the 10-day injured list with a left foot infection on May 10. He was on a rehab assignment with Indianapolis ahead of this trade and looked close to returning, which presented the Pirates with a catcher dilemma.Apr 8, 2026; Pittsburgh, Pennsylvania, USA; Pittsburgh Pirates catcher Joey Bart (14) dives and misses a foul ball by the San Diego Padres during the ninth inning at PNC Park.

Pavely-Imagn ImagesStratton pitched in 47 games over those three seasons, including 36 appearances in 2024, posting a 4.30 ERA over 52.1 innings pitched in his time with the Pirates.He only pitched in one game for the Braves this season, throwing a scoreless inning in a 9-1 win over the Colorado Rockies at Coors Field on May 2. He posted a 4.38 ERA over 21 outings and 24.2 innings pitched with Triple-A Gwinnett. The Pirates have had bullpen issues and are looking for anyone to really help that out in that regard, which makes sense for them to bring Stratton back, who will look to prove himself as a key relief pitcher.
