David Robertson: Everything you need to know

Robertson announced his retirement from professional baseball on his X account Friday. The 40-year-old Robertson waited until the second half this past season to sign with the Phillies, and he's now decided to call it quits after 17 major-league seasons. He will retire after collecting 179 career saves, a 2.93 ERA and 31.9 percent strikeout rate. Robertson made one All-Star team and won a World Series in 2009 as a setup man with the Yankees.

Robertson walked two in a scoreless and hitless inning to earn the save in Monday's 6-5 extra-inning win over the Dodgers. Robertson has handled a setup role since making his season debut Aug. 11. The 40-year-old has done fine with a 3.07 ERA, 1.30 WHIP and 20:7 K:BB, as well as eight holds, over 14.2 innings. He was called on in the 10th inning Monday, as Jhoan Duran had blown a save chance in the ninth after the Phillies had already used Orion Kerkering and Matt Strahm in previous innings. With a deep bullpen in Philadelphia, Robertson is unlikely to see many more save chances this year.

Robertson allowed one hit and no walks with no strikeouts in a scoreless seventh inning Saturday against Miami. Robertson is already up to six holds through 10.2 innings this season. The veteran right-hander has offered a stabilizing presence to the Philadelphia bullpen since his arrival, registering a 2.53 ERA, 1.31 WHIP and 15:5 K:BB. If anything were to happen to closer Jhoan Duran down the stretch, Robertson has given the Phillies another capable arm with closing experience.
