Who Were the Key Players in the Orioles vs Mets Box Score?
Let’s break down the Orioles vs Mets player stats that actually mattered.
Coby Mayo: The Unlikely Hero
Coby Mayo had himself a game. The Orioles’ DH finished 2-for-5 with a home run, 3 RBI, 1 run, and a stolen base.
His 11th-inning inside-the-park homer was pure chaos. Mayo lined a 106.9 mph cutter from Jonathan Pintaro to center field. Rookie A.J. Ewing crashed into the fence trying to catch it. The ball rolled away. Mayo never stopped running.
He scored standing up. Orioles up 7-4.
Christian Encarnacion-Strand
Encarnacion-Strand went 2-for-5 with a homer, 1 RBI, and 2 runs from 3rd base. His 2nd-inning solo shot set the tone early.
Jeremiah Jackson
Jackson added his own solo homer in the 2nd, finishing 1-for-4 with 1 RBI and 1 run.
Marcus Semien (Mets)
The Mets’ 2nd baseman delivered a clutch game-tying RBI double in the 10th inning that scored Encarnacion-Strand’s counter… wait, no. Semien’s double scored the Mets’ tying run in the bottom of the 10th, knotting things at 4-4 before Mayo’s heroics.
Key Takeaway:
- Coby Mayo’s 3-RBI inside-the-parker was the decisive blow
- The Orioles hit 4 home runs as a team
- The Mets left 13 runners on base (compared to Baltimore’s 3)
Bottom line: The Orioles vs Mets batting stats favored Baltimore’s power, but the Mets had chances they couldn’t cash in.
