For Marcus Semien, his performance on the field sometimes would impact how he felt at home.
If the A's shortstop went 0-for-4 with three strikeouts, he would be frustrated and it would be difficult to turn that off.
"It's very intense," he said.
As part of NBC Sports' documentary, "HEADSTRONG: Mental Health and Sports." Semien detailed the ups and downs of playing professional baseball and how he has improved over the years with dealing with the stresses and difficulties it can bring.
Semien, who committed 35 errors in 2015, enlisted the help of Ron Washington in hopes of building his confidence and improving his defensive performance.
And improve he did. Semien cut his errors down significantly, ultimately being named an AL Gold Glove Finalist in 2018.
Still, Semien knows he can't let his focus wane.
"There's been times where you're so hard on yourself over an at-bat and you bring it out to the field and you make an error on the field and you think 'Why did I just make that error?' cuz I was thinking about my at-bat," he chuckled.
But he's working on it.

The A's aren't playing it safe with 2019 first-round draft pick Logan Davidson.
The No. 29 overall pick is among 10 non-roster players the A's invited to spring training Friday.
Davidson, a shortstop, isn't on the A's 40-man roster, but the invite will give him a chance to compete in big league camp. Barring an incredible showing in the Cactus League, the A's No. 7 prospect won't break camp with the A's. But this opportunity allows him to try to impress A's coaches.
In 54 games with the short-season Vermont Lake Monsters, Davidson slashed .239/.345/.332 with seven doubles, four homers and 12 RBI.

The other invitee to keep an eye on in camp is A's No. 6 prospect Nick Allen. While small in stature, the middle infielder is an incredible defensive player and could find himself playing for the A's at some point in 2020. While Marcus Semien is blocking Allen's path at shortstop, the 21-year-old could get a look at second base if none of the other in-house options pan out for Oakland.
Three other top-30 prospects were invited to spring training: Outfielder Greg Deichmann (No. 17), right-handed pitcher Brian Howard (No. 22) and right-handed pitcher Parker Dunshee (No. 24).
Sergio Romo might be headed back to the Bay Area -- just to the opposite side.
The former Giants relief pitcher is a free agent, and according to MLB Network's Jon Morosi, the A's reportedly are interested in acquiring his services.
Romo, 36, is a 12-year veteran who spent the first nine seasons of his career with the Giants, playing a major role in helping San Francisco win three World Series titles in a span of five years. Over 60 1/3 combined innings with the Marlins and Twins last season, he posted a 3.43 ERA and 1.11 WHIP with 60 strikeouts and 20 saves.

Liam Hendricks has Oakland's closer spot locked down, but with Blake Treinen being non-tendered, there could be one or more openings in the A's bullpen. Given that Romo has filled just about every possible role within a major league bullpen over the course of his career, he could be an ideal fit if the price is right.
