The Cleveland Guardians' ace Shane Bieber got some attention back at the trade deadline and with only one year of control left, will likely have trade rumors swirling around him this winter. While he's coming off a down year, he still had a solid 3.80 ERA, 3.87 FIP, and 1.23 WHIP, albeit in an injury-limited 128 innings of work. It also wouldn't be shocking if there were rumors surrounding Triston McKenzie.
While the Guardians definitely have some pitchers that the D-Backs would be interested in if they decide to shop them, the Guards also need outfield help. Steven Kwan is the only one who is penned into an outfield spot. Myles Straw is a great defensive outfielder but has a sub-.600 OPS in each of the last two seasons.
George Valera is their best outfield prospect, and he only had an 84 wRC+ with a 27.8% K-rate at Triple-A last year. Granted, he only just turned 23 earlier this month. Their next best outfield prospect, according to FanGraphs who is older than 19, Wuilfredo Antunez, only just got to A-Ball this season.
If the D-Backs and Guards wanted to get bold, they could probably get a trade put together involving Mackenzie going to Arizona in exchange for a package surrounding Barrosa, Robinson, or even Fletcher. Bieber is more likely to get moved, however, and would slot nicely into the Snakes' rotation.
