OAKLAND -- Marcus Semien enjoyed a breakout season in 2019, in just about every area. The Oakland shortstop became the first A's player to register a top-three finish in the AL MVP race since Miguel Tejada in 2002.

"It means a lot," Semien told NBC Sports California. "It was a very competitive field this year. I think that the game is changing. There are so many players who can do everything on the field -- fielding, base running, scoring runs, producing runs. I'm trying to work on every part of my game to get better, and in the second half, I really made some improvements."

Semien, 29, set career-highs in runs, hits, home runs, doubles, RBI, walks, batting average, on-base percentage, slugging percentage and just about any other stat you can think of. The Bay Area native might have been even better defensively, where he was a Gold Glove finalist for the second straight year.

But despite all of his accomplishments, Semien believes he still has room to improve in 2020.

"I think baserunning is a big one, just getting in scoring position more for our big hitters," Semien said. "We've got great hitters in the middle of the lineup, so walking and getting hits, you want to just make sure you run the bases right. Defensively, turn more double plays, help our pitchers. We're going to have some young pitchers, so we want to make them feel as comfortable as possible."

Last offseason, Semien's most significant development involved plate discipline. He reduced his strikeout total from 131 to 102 and drew a career-high 87 walks, 26 more than the year before.

Semien also matched an A's single-season record by scoring 123 runs, fourth-most in the majors.

"Scoring runs was a big one for me," Semien said. "Solidifying myself in the leadoff spot. I've been moving around the lineup for a couple of years now and just to solidify the leadoff spot and score runs and get in a routine was great."

While he appreciates the individual recognition, Semien's main focus is team success. After experiencing back-to-back Wild Card Game losses, he is optimistic that the A's can make a deeper run next season.

"I think we're going to be good," he said. "We want to start off better than we did last year. I think that our rotation will be more solidified. These last two years, we've added at the (trade) deadline to get our rotation where we want it to be, where this coming season, we'll hopefully start the rotation that we like. Position players are ready. I think that we'll have everybody healthy and it'll be fun."
