Clayton Kershaw made his own piece of history on Sunday against the Baltimore Orioles, but he has one active MLB pitcher ahead of him in a statistic that exemplifies longevity.

Kershaw, who has spent his entire 18-year career with the Los Angeles Dodgers, made a start against the Orioles on Sunday, marking the 29th different team he has faced during his illustrious career. Per Stats Perform, the 37-year-old Kershaw is the 286th player in MLB history to start at pitcher against at least 29 different teams in his career.

It took him the fourth-most starts to face 29 teams, joining an impressive list of pitchers (per Stats Perform):

Greg Maddux — 29th opponent in 654th start (Cleveland)

Roger Clemens — 29th opponent in 631st start (Philadelphia)

Andy Pettitte — 29th opponent in 470th start (Houston)

Clayton Kershaw — 29th opponent in 448th start (Baltimore)

Clayton Kershaw has pitched in numerous MLB stadiums

With Kershaw facing those 29 opponents, he has also made some of those starts in MLB stadiums that no longer exist, such as Shea Stadium, former home of the New York Mets, and Turner Field, former home of the Atlanta Braves.

In all, Kershaw has pitched in 35 different MLB stadiums, tied for second-most among active pitchers (including playoffs, per Stats Perform). Kershaw is tied with Jose Quintana, Max Scherzer and Justin Verlander at 35.

So who is ahead of those four long-standing hurlers? Charlie Morton, now also in his 18th MLB season, leads all active pitchers with 36 stadiums. The 41-year-old Morton has pitched for seven different teams in his career, including two this year with the Orioles and Detroit Tigers.

Morton moving around between the American and National Leagues rather than staying with one team has given him an edge over his colleagues, and it's an edge that could last for some time. The Athletics are expected to move into their new home in Las Vegas in 2028, the next new ballpark that is expected to open. It will be interesting to see if any of the pitchers currently on the list above will still be active when baseball comes to Las Vegas.
