Apparently, David Robertson likes Philadelphia and the Phillies like him. The 40-year-old right-hander was officially added to the 26-man roster Sunday after spending the required 15 days with the Triple-A Lehigh Valley IronPigs. It’s the third time that Robertson has been in a Phillies uniform in his career, which makes him only the third player to have three separate stints with the team.

Robertson went unsigned during the offseason but kept himself in shape with an eye on signing with a team later in the season. After a workout that Robertson held for teams, the Phillies signed him to a major league contract for the rest of the season and assigned him to Lehigh Valley to get into game shape to pitch in the majors. MLB rules stipulate that a player who is assigned to a minor league team must spend 15 days there unless there is an injury that necessitates him returning to the majors.

Robertson made six relief appearances at Triple-A with four of them going well and two of them being forgettable. In back-to-back relief appearances earlier this month, the right-hander was tagged for three earned runs in an inning of work. Those were the only runs allowed by Robertson, who went 3.1 innings in his four other relief appearances without allowing a run on four hits and no walks. Overall, Robertson went 0-1 with a 10.13 ERA in his six relief appearances.

The Phillies are hoping that Robertson can help to solidify a bullpen that has been inconsistent at times throughout the season. He also brings the postseason experience to the bullpen and while he is the oldest member of the bullpen, he has not thrown many innings this season, giving the team hope that his arm will be fresh and he can contribute at a high level for the rest of the season and postseason.
