Cody Bellinger’s Struggles Aren’t Just Small Sample Woes
I’d be a liar if I said the Los Angeles Dodgers are struggling. At 16-7, they have been as dangerous as expected and currently hold the best record in the National League while leading in both runs scored and ERA. But the offense still isn’t firing on all cylinders, with Cody Bellinger, Max Muncy, and Joc Pederson all off to fairly slow starts. This is an especially concerning development for Bellinger given that he was responsible for approximately eight wins in 2019, hitting .305/.406/.629 with a 162 wRC+ and 47 homers while besting Christian Yelich for the NL MVP award.
Outside of hitting a couple home runs against the Angels on Friday, Bellinger’s 2020 has been his most forgettable campaign in the majors. A triple-slash of .187/.245/.341 (57 wRC+) has left him hovering around replacement level, and in a 60-game season, we’re only a week away from the halfway point.
Baseball is a game of adjustments, and even during an MVP campaign last year, Bellinger found pitchers adjusting to him with (slightly) successful results. On the morning of June 1, 2019, Bellinger’s OPS stood at an awe-inspiring 1.208; his batting average had fallen below the .400 line just a week before. You wouldn’t call the .262/.372/.561 (136 wRC+) he hit over the rest of the season an actual problem, but it was distinctly below his early-season standards. It wasn’t a complete sea change, but pitchers gradually started throwing him more breaking pitches as 2019 progressed, a trend that has continued in 2020. When Bellinger surged in April and May of last year, only 20.9% of his pitches were breaking pitches, a number which increased to 25.6% from June to September and to 28.7% in 2020, passing the 30% line so far in August.
And pitchers haven’t yet been punished for this approach. Bellinger has swung at 51.6% of all breaking pitches in 2020, compared to 34.2% in April/May 2019 and 41.9% from June on. Swinging at more breaking pitches has resulted in fewer hits than before; after getting 14 hits against the bendy stuff in April/May, including five homers, he only managed 16 over the next four months and he has just two in 2020. Since June 1, 2019 in 122 games, Bellinger has just two hits against curveballs, with none coming in 2020. Read the rest of this entry »
