Former Blue Jays currently featured on the AL/NL Championship Series rosters

Tim Locastro – OF
A 13th-round pick of the Blue Jays from the 2013 MLB Draft, outfielder Tim Locastro spent roughly two years within the organization before he was traded to the Los Angeles Dodgers in exchange for international bonus pool funds, which would later be used to help sign Vladimir Guerrero Jr. without facing discipline for exceeding their pool allotment.
Locastro made his MLB debut with the Dodgers in 2017 but has struggled to carve out a full-time role since then, splitting time between the minors and the big leagues while working in a bench capacity.
He would be traded two years later to the Arizona Diamondbacks and would be acquired by the Yankees in July of the 2021 campaign, returning to the Bronx Bombers this season on a MiLB deal. The righty-batter currently owns a career .227/.325/.331 slash line with a .656 OPS through 475. For Locastro, his calling card is his speed, as he has swiped 39 bags compared to five caught stealing.
The New York product has not made an appearance in the ALCS yet.
