Sean Jamieson is a minor league infielder.
Sean was drafted out of Canisius College in Buffalo, NY in the 17th round of the 2011 amateur draft by the Oakland Athletics. Signing immediately with the A's, he began his professional career that summer with the Vermont Lake Monsters, where he hit .35 in 69 games, with 27 stolen bases in 32 attempts as the team's starting shortstop. In 2012, he moved up to the Burlington Bees of the Midwest League where in 18 games he hit .234 with 25 doubles and 10 homers, adding another 25 steals in 30 attempts. On August 20th, the A's traded him to the Arizona Diamondbacks in return for major league shortstop Stephen Drew. He hit .327/.431/.473 in 13 games for the South Bend Silver Hawks after the deal, adding five more steals to give him 30 on the year, tying Tyler Goeddel and Todd Hankins for 9th in the Midwest League.
Jamieson was on Team Canada for the 2013 World Baseball Classic Qualifiers, backing up Jonathan Malo at SS and not getting an at-bat as Canada advanced to the 2013 World Baseball Classic (for which he did not make the cut, Cale Iorg becoming the starter and Malo the backup). He hit .287/.370/.462 with 33 doubles and 80 runs for the '13 Visalia Rawhide. He was 6th in the California League in doubles.
Sean continued to bat well with the 2014 Mobile BayBears (.298/.362/.429 in 91 G). Despite his fine year, he returned to Mobile in 2015 and started strong (.317/.411/.441, 31 R in 47 G) then joined Canada for the 2015 Pan American Games. This time, he was a starter for the Canadians, hitting .179/.369/.179 with six walks and five runs in eight games. He provided strong glovework at short, with 11 putouts, 20 assists and no errors as Canada led the Games in fielding percentage. In the Gold Medal game, a 7-6 win over Team USA, he hit leadoff, going 1 for 5 with a walk and a run. He came up in the bottom of the 10th with Canada down 6-4, two on and none out against Jake Barrett. He tried to bunt with a two-strike count and fouled it off for a strikeout, but Canada rallied to win. They became the first country other than Cuba to win multiple Pan American Games baseball Golds, let alone defend a Gold.
