Entering Monday’s start against the Phillies, Dodgers ace Clayton Kershaw had made 287 starts and pitched 1,917 innings over parts of 10 seasons. He’s done a lot of things, like winning a Cy Young Award, an MVP Award, winning 20 games, posting a sub-2.00 ERA. One thing he had never done is allow a grand slam.
Kershaw had loaded the bases 103 times coming into Monday’s action. Batters hit .193/.233/.250 off of him with 17 hits, of which only five went for extra bases (all doubles). In 2017, opposing hitters were 0-for-6 with five strikeouts with the bags packed.
Phillies outfielder Aaron Altherr changed that in a big way. In the bottom of the sixth inning, trailing 2-0, the Phillies loaded the bases on a Ty Kelly walk, a Freddy Galvis single, and a Rhys Hoskins walk, bringing up Altherr. After running the count even at 1-1, Altherr blasted a grand slam into the second deck at Citizens Bank Park for the first grand slam ever hit off of Kershaw. According to Statcast, the ball left his bat at 107.6 MPH and went 418 feet.
Following the grand slam, Altherr improved his slash line to .276/.348/.521 along with 17 home runs, 55 RBI, and 51 runs scored in 362 plate appearances.
Kershaw was lifted after six innings. He gave up the four runs on four hits and two walks with six strikeouts. He still owns a sterling 17-3 record with a 2.26 ERA and a 194/30 K/BB ratio in 163 innings on the season.
