William Klein: Breaking News

Earns first big-league save

Klein struck out one in a perfect inning to earn the save in Tuesday's 5-4 win over the Padres. The Dodgers took the lead in the top of the ninth inning, and they'd already deployed Alex Vesia, Blake Treinen and Tanner Scott in previous frames to keep the game tied. That left the save chance to Klein, and got the job done on 10 pitches (seven strikes) for his first big-league save. Klein has added four holds over his last eight appearances, indicating he's getting a bit more leverage work. On the year, he has a 2.33 ERA, 1.24 WHIP and 20:6 K:BB through 19.1 innings. Tuesday's usage likely isn't going to lead to many more saves for the right-hander, as he has mostly worked as a middle reliever this year.

Fans four in two relief frames

Klein allowed two hits and issued one walk while striking out four batters over two scoreless relief innings against the Rangers on Sunday. Klein entered in the eighth inning with no outs and two runners on base. He allowed a single to allow one inherited runner to score and uncorked a wild pitch to permit the second inherited runner to cross the plate, but the righty reliever struck out the final two hitters in the frame to escape additional damage. Klein had a less eventful ninth inning, allowing an infield single but facing the minimum amount of batters thanks to a caught-stealing. Despite not being his sharpest Sunday, Klein lowered his season ERA to 1.17 through 7.2 innings. He's posted a 9:3 K:BB and has a win (but no holds or saves) on his ledger.

Makes World Series roster

Klein is on the Dodgers' World Series roster. Klein has not pitched in nearly a month, having been left off the roster for each of the Dodgers' first three postseason series. He'll likely be limited to low-leverage appearances during the World Series.
