Pitchers Are Way Ahead of Hitters So Far
Starting the season after a long layoff and an abbreviated training camp was bound to put players in different positions of readiness in the season’s early going. When a season starts in late March or early April, teams enjoy a full spring training but weather can have an effect on hitters. Better weather means better offensive production, so it seemed possible that a late-July start might help hitters skip some of the early-season struggles we typically see; the universal designated hitter also seemed likely to help move things along. So far, it has been a bit of a mixed bag.
Through yesterday’s action, teams are scoring 4.5 runs per game, which is down from last year’s 4.8 full-season mark despite the addition of the designated hitter in the National League. Of course, the first week of the 2019 season saw teams score an average of 4.3 runs per game, so there are more runs than the beginning of last season. Runs alone probably aren’t going to tell us if pitchers have a bigger advantage than they normally do, though, particularly when changes to the ball over the last few seasons have had a pretty dramatic effect on scoring. To get a sense of the last few seasons, here are some end-of-season numbers since 2017 (excluding pitchers hitting), along with the start of this season:
Season | HR/PA | IFFB | BB% | K% | ISO | BABIP | wOBA |
---|---|---|---|---|---|---|---|
2017 | 3.4% | 9.6% | 8.7% | 21.2% | .175 | .301 | .326 |
2018 | 3.1% | 10.3% | 8.6% | 21.7% | .165 | .297 | .320 |
2019 | 3.7% | 9.8% | 8.7% | 22.4% | .187 | .299 | .325 |
2017-2019 | 3.4% | 9.9% | 8.7% | 21.8% | .176 | .299 | .324 |
2020 | 3.3% | 11.2% | 9.4% | 23.3% | .167 | .276 | .313 |
Home runs are certainly down from last season, but compared to the last three seasons, the dip isn’t huge. We have seen an increase in the rate of infield fly balls, walks, and strikeouts. The power numbers are down some, but the big drop from previous seasons’ numbers concerns BABIP. The increase in walks isn’t enough to offset the greater number of strikeouts, the lack of power resulting in weaker contact, and considerably worse overall offensive numbers. Before we compare these numbers to typical early-season numbers, let’s add in some plate discipline stats as well:
Season | O-Swing% | Z-Swing% | Contact% | Zone% | SwStrk | vFA |
---|---|---|---|---|---|---|
2017 | 26.2% | 65.8% | 77.7% | 51.1% | 10.4% | 93.3 |
2018 | 26.9% | 65.6% | 77.2% | 51.0% | 10.6% | 93.2 |
2019 | 28.6% | 66.0% | 76.5% | 49.3% | 11.1% | 93.4 |
2017-2019 | 27.2% | 65.8% | 77.1% | 50.5% | 10.7% | 93.3 |
2020 | 25.9% | 64.5% | 73.9% | 49.8% | 11.7% | 93.3 |
