Marcus Semien fell short of winning the AL MVP Award, but his third-place finish might be just the beginning.
At 29 years old, the A's shortstop still is very much in his prime and has significantly improved in each of his five seasons with Oakland.
When Semien first joined the A's at the age of 24, he was a decent hitter but looked completely lost in the field. In 2015, he committed a league-high 35 errors, prompting many to believe that he could never develop into a major-league shortstop.
But with the help of Ron Washington, Semien went to work. He spent hours upon hours working on his footwork, glovework, and consistency. Fast forward to 2019 and Semien has transformed into a back-to-back Gold Glove Award finalist.
Semien's offensive development has been just as impressive. This past season, the Bay Area native slashed .285/.369/.522 with 33 home runs, 43 doubles, 92 RBI, and 123 runs scored. He notched career-highs in just about every offensive stat imaginable, ranking near the top of the majors in all of the important categories.
Most impressive, Semien's 8.1 WAR (wins above replacement) was fourth-best in baseball, behind only Mike Trout, Alex Bregman, and Cody Bellinger. Semien started all 162 games at shortstop, batting in the leadoff spot for 145 of those contests. And the scariest part for the rest of the league is that he continues to get better.
"He becomes a better hitter every year," A's manager Bob Melvin said earlier this year. "Nobody works harder than Marcus Semien. He knows what he needs to work on."
After the All-Star break, Semien arguably was the most productive hitter in baseball. In 70 games, he slashed .304/.396/.621 with 19 homers, 22 doubles, five triples, 44 RBI, and 62 runs.
If Semien continues at that rate next season, it would translate to 44 home runs, 51 doubles, 12 triples, 102 RBI, and 143 runs over the course of 162 games. That certainly is MVP-caliber.
Of course, the A's have a major decision to make -- Semien is set to become a free agent after the 2020 season and figures to see some big-money offers. Will Oakland sign its star shortstop to an expensive extension or instead turn the reigns over to young prospect Jorge Mateo?

Semien is entering his final year of arbitration, where he is projected to get $13.5 million. After that, the A's could choose to make a qualifying offer to Semien for 2021, but there is no guarantee he would accept.
If 2020 does end up being Semien's last year in Oakland, it figures to be another special one. This year he was an MVP finalist. Perhaps next year he'll just be the MVP.
