- Trumbo pitched (hitting 91-97 mph) and played first base for Villa Park High School, in the shadows of Angel Stadium. He hit .425-6-25 in 2004, his senior year. He also impressed scouts with his well-rounded game in April at the National Classic, as Villa Park High won the nation's most prestigious high school tournament. And Mark was the event's most outstanding player.
- In 2004, Mark signed a letter of intent to Southern Cal. His father is a huge USC fan. But at the last minute, on August 16, 2004, the Angels signed him, as a third baseman, which was a surprise. Most everyone else had Trumbo pegged for the pitcher's mound.
- Mark grew up a big fan of the Angels, living in the neighborhood of Angels Stadium. He remembers watching power hitters Tim Salmon and Troy Glaus.
In 2005, Trumbo led the Pioneer League in doubles and ranked second in extra-base hits.
In 2006, Baseball America's Prospect Handbook rated Trumbo as 12th-best prospect in the Angels' organization. (They had him at #11 in the spring of 2005.) In the spring of 2007, they had Mark as 29th-best prospect in the Angels' farm system. And that is exactly where they had Trumbo in the spring of 2008, #29.
In 2009, Baseball America's Prospect Handbook had Mark all the way up to 8th-best prospect in the Angels organization. They had him at #11 in the spring of 2010. And finally, he was ranked the 9th-best prospect in the Angels' farm system in the winter before 2011 spring training.
In 2010, Trumbo tied Mike Moustakas for the minor league lead with 36 homers. He also paced the PCL in runs (103), RBIs (122), and total bases (307).
That year, the Angels named Mark their Minor League Player of the Year.
In 2011 Mark led all rookies with 29 home runs and 87 RBIs while batting .254 in his rookie campaign, but finished second in Rookie of the Year voting to Jeremy Hellickson of the Tampa Bay Rays.
A television analyst referred to Mark Trumbo and Mike Trout as "T 'n T"—a dynamite combination.
The Oakland A’s stumbled out of the gate to an 18-25 record through May 21 2012. It was then that the 2012 TNT boys sparked an eight-game winning streak that put the Angels back into contention—and rekindled an old nickname.
Few players wear their passion on their sleeve like Trumbo.
"I don't think anybody can care too much, but I definitely think he is a guy who's very difficult on himself; a lot of self-imposed pressure," Angels hitting coach Jim Eppard said. "As he brings that into better focus, as he matures, as he gains that experience as a Major League player, as a Major League hitter, those stretches are going to become shorter and shorter as we go."
Trumbo loves music. He listens to a variety of bands and plays several instruments, though he wishes he had more time to practice.
"I play drums from time to time," Trumbo said. "I've played live a couple times, but I mostly do it for fun."
Trumbo said he would not mind playing music for a career after baseball.
In 2014, Mark teamed up with some other players on the D-Backs to form a group. Fender Guitars has supplied a music room for the group to practice.
Trumbo plays drums and lead guitar. Bronson Arroyo is on guitar and vocals. Wade Miley plays base guitar. Aaron Hill plays rhythm guitar. Kurt Gibson's oldest son plays guitar and sings. A.J Pollack is also in the band.
In 2016, Trumbo was named Sporting News' AL Comeback Player of the Year.
In 2016, Trumbo was selected as the AL's Comeback Player for the Players Choice Award.
Mark really fit in well with the Orioles. There could have been legitimate questions, considering Baltimore was Trumbo's fourth team in four years.
"We thought he'd be a good fit with how our clubhouse works," Manager Buck Showalter said. "He's been a real contributor from that standpoint. He doesn't take himself too seriously. He is funny, dry and very humble. There are times when you are around him and he never thinks he's going to hit another home run . . . or he has never hit one in his whole life."
June 2004: The Angels signed Mark to a $1.425 million contract after drafting him in the 18th round, out of Villa Park High School in Orange, California.
That bonus set a record for a bonus for a non-draft-and-follow player selected after the 10th round. Tim Corcoran is the scout who signed him.
Though most scouts had him as a pitcher, including the Angels, the more they looked at him over the summer of 2004, the more excited they got about his powerful bat. So they signed him as a first and third baseman.
December 10, 2013: In a three-team trade, the Diamondbacks received Trumbo from the Angels, along with two players to be named, one from the White Sox, one from the Angels. The D-Backs sent OF Adam Eaton to the White Sox and LHP Tyler Skaggs to the Angels. The Angels also received Hector Santiago from the White Sox.
