What happened: Thursday's blast for the Baltimore Orioles completed the three-at-bat sequence. The run originated against the Chicago Cubs on Wednesday, when O'Neill connected for solo shots in both of his plate appearances after entering as a substitute.
Why it matters: Reaching this power milestone shifts how opposing managers approach him in the lineup. The surge also delivers immediate run production for Baltimore midway through the regular season.
By the numbers: The first two home runs arrived in the seventh and eighth innings on Wednesday, with the second hit back-to-back alongside teammate Coby Mayo. His seventh-inning shot came off Drew Pomeranz, followed by an eighth-inning blast against Caleb Thielbar.
What to watch: Opposing pitchers will face a strategic decision on whether to pitch around O'Neill during his subsequent at-bats.
