Pitching style
Mortensen threw four pitches: a four-seam fastball and two-seam fastball at 88–90 mph, a slider at 85–87, and a circle changeup at 79–81. The slider tended to be used more against right-handed batters, and the changeup was used more against left-handed hitters. Mortensen's slider had a somewhat unusual and unpredictable movement:My slider isn’t a typical slider. It doesn’t necessarily break right-to-left. It has more depth to it, so it’s more of a down-ball. It also has three different movements, depending on where my release point is. When I really accentuate staying on top of it — away to a righty — it will have a little depth and a little right-to-left movement. If I try to throw it down the middle, it’s more straight down. Sometimes it kind of screws. It's basically because of the way I grip it. I kind of cock my wrist a little bit. To be honest, I try to throw it as hard as I can and it just kind of does what it wants to do.
Personal life
On the night of October 2, 2009, Mortensen was arrested on suspicion of drunken driving and spent the night in the Santa Clara County jail.
Mortensen is married to Janna and they had two children, Miles and Harper. Miles died at the age of 6 on September 11, 2018 after a long battle with stage IV Neuroblastoma.
