No. 15 Jonathan Davis, OF
I'm not going to make a Korn pun, no matter how badly I would like to.
Davis, a true speed demon both on the bases and in the outfield, was in the Blue Jays' organization all the way up until 2021, spending ample time in both the major and minor leagues for the club.
I'm not sure if it was just a lack of a serious shot or if the talent just isn't there, but Davis never put it together in the majors, appearing in 122 games for the Jays, hitting four home runs with a .180 batting average and a ghastly 51 OPS+.
No. 14 L.B. Dantzler, 1B/OF
Dantzler went to school in South Carolina and displayed a ton of pop in his bat as well as above-average contact skills. Unfortunately for both him and the Jays, he could never put it together upon his joining the Blue Jays organization.
Dantzler stayed in the org through 2016 but never once managed to hit double digit home runs. The talent was there, as he drove in 64 runs in 91 games in 2014 and played a really solid first base, but he just could not do enough to stick around in baseball.
No. 13 Tim Locastro, INF/OF
The very same Tim Locastro that has appeared in parts of the last season six seasons in the bigs, his career didn't go very far in Toronto before his being dealt to the Dodgers in 2014 for three international signings slots.
Locastro has always been a speed demon who only recently found a full-time home in the outfield. He has never hit for much pop but provides values to clubs as a defensive specialist/pinch runner, but nothing more.
All told, he spent parts of two seasons with the Jays organization, playing in 43 games in 2013 and 67 in 2014, hitting a total of two home runs along the way with 44 stolen bases in 50 attempts.
No. 12 Tim Mayza, LHP
It's a bit strange to think about, but 2023 will be Tim Mayza's 11th season in the Blue Jays organization.
Mayza attempted to be a starting pitcher early on but couldn't find success as a starter so the Jays tunred him into a relief option and he has flourished from there.
Injuries (2019 Tommy John surgery) have taken valuable playing time away from him, but he still projects to return in 2023 once again as an oft-used left-handed option out of the Jays' big league bullpen.
No. 11 Jake Brentz, LHP
Brentz was taken in the 11th round by Toronto and wound up sticking around for just a few seasons before being traded to Seattle in exchange for Mark Lowe.
After the Seattle experiment didn't work out, they flipped him to Texas who later flipped him to Kansas City where he finally made his big league debut.
Brentz emerged as a surprise standout reliever for the Royals in 2021, appearing in a whopping 72 games for the club, striking out 76 in 64 innings and posting a dazzling 125 ERA+. Last season, the wheels completely came off as he posted a 23.63 ERA in eight appearances.
At the conclusion of the 2022 campaign, the Royals made the easy decision to non-tender Brentz, who remains a free agent.
