Starting pitcher Marcus Walden played in the Toronto Blue Jays minor league system from 2007 to 2014, then bounced around the minor leagues before finally making his major league debut at the age of 29 in 2018, four years after having spent some time on a major league roster without getting into a game. He was taken by the Blue Jays in the 9th round of the 2007 amateur draft, a few slots after Michael Stutes.
He began his career with the GCL Blue Jays and went 2-4 with a 3.05 ERA in 12 games (10 starts) for them in 2007. With the Auburn Doubledays in 2008, Walden was 2-3 with a 4.80 ERA in 14 games (11 starts) and in 2009, he was 2-1 with an 8.64 ERA in 4 starts for the Dunedin Blue Jays - though he missed most of that season and all of 2010 due to Tommy John surgery.
Returning an improved pitcher for 2011, Walden was 6-6 with a 3.24 ERA in 28 games (13 starts) for the Lansing Lugnuts. He went 14-4 with a 2.97 ERA in 27 games (26 starts) split between Lansing (14 G, 5-2 W-L, 3.10 ERA) and Dunedin (13 G, 9-2 W-L, 2.85 ERA) in 2012 and in 2013, with the New Hampshire Fisher Cats, he was 6-14 with a complete game shutout and a 3.71 ERA in 26 starts.
Walden spent four days on the roster of the Toronto Blue Jays in April 2014 without appearing in a game. Shortly thereafter, he was designated for assignment. The Oakland A's then signed him and assigned him to Triple-A. He pitched a single game in the Cincinnati Reds system in 2015, joined the independent ranks for the rest of the year, was in the Minnesota Twins system in 2016 (posting a 2.40 mark in 42 games) and joined the Boston Red Sox system in 2017. With the Triple A Pawtucket Red Sox, he went 10-6 with a 3.92 ERA in 29 games (15 starts).
