Between 2019-2024, the shortstop turned second baseman hardly missed a game between the Athletics, Blue Jays and Rangers, and hit 20 or more home runs in every year outside of the COVID-19-shortened 2020 season.

Semien’s 2021 campaign was the pinnacle of his career, as he slugged 45 home runs in Toronto to finish third in AL MVP voting. In fact, it was Semien’s second time finishing top-3 in MVP voting, a feat he also accomplished in 2019 with Oakland. 

In 2023, he slashed .276/.348/.478 with an .826 OPS, 29 homers and 100 RBI, helping the Rangers to their first-ever World Series. Between 2019 and 2023, Semien eclipsed seven or more wins above replacement according to Baseball Reference (bWAR) three times. 

But things went south from there. Over the next two years, he slashed just .234/.307/.379 with a paltry .686 OPS. In 2025, despite battling injuries, he hit just 15 home runs.

Semien’s value comes from his glove, as even with disappointing offensive numbers, he compiled 4.1 and 3.3 bWAR, respectively, over the past two years. He was rewarded for his efforts, earning his second career Gold Glove in 2025.

The trade is far from a straight salary dump for the Mets, though, as Semien comes with a hefty price tag.
