Blue Jays prospects Jake Bloss, Aaron Parker and Jake Cook named to Arizona Fall League All-Star team

Three of the Toronto Blue Jays' prospects earned spots on the Arizona Fall League All-Star team after strong showings this fall: pitcher Jake Bloss, catcher Aaron Parker and outfielder Jake Cook.

Bloss used the AFL to show he is moving past the injuries that slowed him over the past couple of seasons in the Blue Jays’ minor league system. The 25-year-old right-hander had Tommy John surgery, and then a right teres major strain ended his 2026 season in July. He had thrown only 51 innings over two years before arriving in Arizona. With the Mesa Solar Sox, he struck out 11 and walked only two in 10 2/3 innings over five starts. He opened with two perfect innings, and his fastball reached 95.6 mph.

He did give up 10 runs, but seven of them came in a single one-inning start against the Desert Dogs, and his control and command looked strong otherwise. That is a promising sign as he works his way back into a viable option for Toronto in 2027. Fans have been waiting to see him in a Blue Jays uniform since he arrived in the Yusei Kikuchi trade at the 2024 deadline.

Jake Bloss, Aaron Parker and Jake Cook stood out in Arizona

Parker was hot at the plate for the Solar Sox, hitting .351 with a .939 OPS, one home run, nine runs scored and eight RBIs in 10 games. He was also a perfect seven-for-seven on stolen bases.

The 23-year-old slugger is coming off a breakout 2026 season with Double-A New Hampshire, where he hit .253 with an .814 OPS, 19 home runs, 46 runs scored, eight doubles, 48 RBIs and 12 stolen bases in 87 games. The 19 homers were a career high, as he had never hit more than eight in a season. The main thing to watch is his strikeout rate, which was 32.3 per cent during the regular season.

Cook hit .328 with a .743 OPS, 16 runs scored, two doubles and four RBIs in 14 games for the Solar Sox. He also showed why his 80-grade speed makes him one of the top speedsters in the Jays’ organization, swiping 10 bases in those 14 games. Cook, a third-round pick in 2025 out of Southern Mississippi, played primarily for Single-A Dunedin in his first professional season. There he hit .250 with a .738 OPS, five home runs, 56 runs scored, 10 doubles, four triples, 40 RBIs and 21 stolen bases in 72 games.

While Parker and Cook may still be at least a couple of years away from making an impact in Toronto, Bloss will hope his encouraging AFL showing makes him a factor for the Blue Jays in 2027. If he can stay healthy and keep his velocity into spring training, he could give the rotation a useful boost.
