Callihan, 25 in June, was a third-round pick of the Reds in 2019. Due to the pandemic and Tommy John surgery in 2021, he didn’t play much in the years following his draft. He is coming off a season in which he posted some pretty strong numbers. He got into 73 games this year, 69 of those in Double-A and four in Triple-A. In that time, he slashed .276/.359/.429 for a wRC+ of 133.

Given his small amount of experience at the top minor league level, he will probably head back to that level next year. He has experience at the three non-shortstop infield positions and left field as well, so he can give the club some depth at a variety of spots around the diamond.

Mey, 23, has great stuff but hasn’t really been able to harness it yet. Over the past four years, he has thrown 123 2/3 innings with a 4.66 earned run average. He struck out 26.1% of batters faced in that time and got plenty of ground balls but also walked 17.5% of batters faced.

He has yet to reach Triple-A and has just 19 Double-A appearances. Given that and his lack of control, he seems to be a bit of a long-term project for the Reds. If they can develop him in the coming years, he could factor into their big league bullpen down the line.

• The Reds have added outfielder Michael Siani, infielder Tyler Callihan and right-hander Lyon Richardson to their player pool, Bobby Nightengale of the Cincinnati Enquirer tweets. All three players – Siani (No. 7), Callihan (No. 8) and Richardson (No. 11) – rank among the Reds’ best prospects at MLB.com. The 21-year-old Siani was a fourth-round pick of the Reds in 2018 who batted .253/.333/.339 with six home runs and a whopping 45 stolen bases across 531 plate appearances in Single-A ball last season. Callihan, 20, joined the Reds as a third-rounder last year and hit .263/.298/.442 with six homers and 11 steals in 238 rookie ball plate appearances. Richardson, a 2018 fourth-rounder, logged a 4.15 ERA/3.76 FIP in 112 2/3 innings at the Single-A level last season. FanGraphs’ Eric Longenhagen wrote in May that the hard-throwing Richardson, 20, has the potential to become a top 100 prospect by 2021.
• Shortstop Orelvis Martinez is now in the Blue Jays’ player pool, per Ben Nicholson-Smith of Sportsnet. The Dominican Republic native was a pricey July 2 signing in 2018 for the Blue Jays, who inked Martinez to a $3.5MM bonus. The 18-year-old has continued to show great promise since then, evidenced in part by the .275/.350/.549 line and 150 wRC+ he put up in 163 plate appearances in rookie ball during his first pro action last season. FanGraphs (No. 4), MLB.com (No. 7) and Baseball America (No. 7) each place Martinez near the top of Toronto’s farm system.
