About Rob Rasmussen

Born 1989. Rob Rasmussen is an American baseball player.

Robert Paul Rasmussen (born April 2, 1989) is an American former professional baseball pitcher. He played in Major League Baseball (MLB) for the Toronto Blue Jays and the Seattle Mariners. Prior to his professional career, Rasmussen attended the University of California, Los Angeles (UCLA) and played college baseball for the UCLA Bruins.

Early life Rasmussen is a native of Arcadia, California. He attended Clairbourn School and then Polytechnic School in Pasadena, California. He established himself as an elite high school prospect despite attending a small high school with only 360 students. As a four-year starter for the varsity baseball team at Polytechnic, Rasmussen compiled a 38–2 record and 1.04 ERA, recording 492 strikeouts in 248 innings over his career. Rasmussen earned further attention from professional and collegiate baseball scouts while playing in the Babe Ruth League between high school seasons, pitching for three Babe Ruth World Series championship teams and posting a 17–0 record.

Collegiate career After being selected in the 27th round of the 2007 MLB draft by the Los Angeles Dodgers, Rasmussen decided to attend the University of California, Los Angeles (UCLA) to play college baseball for the UCLA Bruins. In his first season at UCLA, Rasmussen made only 10 appearances and 2 starts after sustaining a broken left foot off a line drive comebacker in the third inning of his 2008 collegiate debut against UC Santa Barbara.

During the summers of 2008 and 2009, Rasmussen pitched for the Orleans Firebirds of the Cape Cod Baseball League. After going 2-0 with a 0.96 ERA in his first three starts for the Orleans Firebirds in the summer of 2009, Rasmussen was selected to start on the mound in the Cape Cod League All-Star game at Fenway Park on July 23, 2009. He finished the Cape Cod season going 4-0 with a 1.80 ERA.

During the 2009 season, Rasmussen made 18 appearances, posted a record of 4-2 with a 6.75 ERA, while totaling 51 strikeouts and 26 walks in 44 innings. Rasmussen earned a victory in the Bruins' season-opener, a 13-1 win against UC Davis.

His Sunday pitching contributed in making the 2010 team the best UCLA baseball team (51-17 record) in school history and the second best team in the country. The team went on to play in the 2010 College World Series and was defeated by South Carolina in the NCAA Championship Series. Rasmussen went 11-3 with a 2.72 ERA, collecting 128 strikeouts in 109 innings.

According to the Under Armour 2010 Draft Scouting Report: "Rasmussen is a pretty advanced college lefty with an interesting combination of pitchability and stuff. He has four pitches he's around the plate with, though he does need to be a little more efficient with his pitches. He's a bit undersized, which might concern some, but he does a nice job mixing his pitches and keeping hitters guessing. If the spike in velocity he showed early in the spring is still around all season, he could sneak even further up Draft boards."
