Matt Chapman Is a Weapon of Mass Destruction

Matt Chapman has long been a sabermetric darling, but it was largely on the basis of combining elite defense at the hot corner with merely above-average offense. While he’s always hit the ball hard, his rather low BABIPs and middling contact skills have been a ceiling on his production at the plate. With his glove in decline and entering his age-30 season, it was an open question as to how lucrative he would find free agency at the end of the season. But Chapman’s 2023 season has been an offensive tour de force, with a seasonal line of .364/.449/.636, a 202 wRC+ and 2.0 WAR as of Thursday morning. The Blue Jays have gotten better than a .700 OPS at only three positions this season (first base, third base, shortstop), and Chapman’s sterling performance is one of the main reasons the offense has still been able to rank sixth in the American League in runs scored.
Just to get it out of the way: Chapman’s not going to hit .364 for the 2023 season. Looking at the zBABIP that ZiPS calculates for him, it thinks his BABIP should be more like .300 based on how he’s hit, not the current .461 figure. But what does look like it’s here to stay is the level of power he’s displayed; if he were a computer program, David Lightman would have skipped Global Thermonuclear War and played Matt Chapman instead. An average exit velocity of 95.6 mph and a hard-hit rate of 66.7% are in ultra-elite territory, and small sample sizes for data like these are relatively meaningful. Chapman’s barrel percentage so far has approached a ludicrous 30%, a number nobody’s been able to touch in a full season (Aaron Judge at 26.2% in 2022 is the only player so far to beat 25%).
