Over his past 22 starts dating to June 21, 2015, Jake Arrieta has surrendered four home runs ... and hit three.

Arrieta’s second-inning dinger at Chase Field was the longest by a pitcher for the eight seasons for which we have full data. His 442-foot long ball was longer than any he’d allowed in the past five seasons. He’s allowed only one longer than that in his career: a 447-foot homer by Yunel Escobar on June 15, 2011.

Two of Arrieta’s three home runs have been calculated at more than 410 feet. His average homer distance of 411 feet is tied for the second-longest of any pitcher with at least three homers since 2009.

As noted above, the homer was Arrieta’s third over the past two seasons, the second-most among pitchers in that span. Only reigning (and back-to-back) Silver Slugger winner Madison Bumgarner has more, with six. Bumgarner and Arrieta are two of just four pitchers to hit multiple homers in that span, along with Zack Greinke and Mike Leake, both with two.

Arrieta, who spent the first three-plus years of his career in the American League with the Orioles, didn’t have a single homer in his career until last season, his second full campaign in Chicago. The newly anointed slugger has a long way to go if he wants to make history for Cubs pitchers at the plate. Pitcher Carlos Zambrano hit 23 homers as a member of the Cubs, setting the standard.

Arrieta’s home run made him the third pitcher to homer so far. The Giants, with Bumgarner, and Dodgers, with Kenta Maeda, are the others.

Though Arrieta’s power is a newfound addition to the Cubs’ hitting corps, they’ve had prior power-hitting pitchers in recent memory, too. Travis Wood had three homers each in 2013 and 2014. The 2013 Cubs had four different pitchers hit at least one dinger (Wood, Jeff Samardzija, Edwin Jackson, Scott Feldman).

Since 2011, Zambrano’s final year with the club, the Cubs’ 17 homers from pitchers trail only the Giants (18).

Bumgarner’s beyond-the-fence power was on display this weekend, too. The righty hitter went yard against Dodgers ace Clayton Kershaw. The Giant, whose 12 career home runs make him one of just two active pitchers with double-digit homers (Yovani Gallardo, 12), had hit one off Kershaw before.

Kershaw has given up only two homers to pitchers in his career, both to Bumgarner. Bumgarner joined the list of 15 batters with multiple career homers off the three-time Cy Young winner. Kershaw has given up four home runs in 15 career starts at AT&T Park, and half of those have been to that same opposing pitcher.
