Today at the Prospect Stock Watch we take a look at a rising pitcher from the National League and a couple of shortstops on different ends of the development spectrum.
Mitch Keller | RHP | Pirates
Keller, 20, reminds me a little bit of Jameson Taillon — as a pitcher with some giddy-up on his fastball that has above-average control at an early stage of the development curve. The 2014 second-round pick is still working to polish his command but he could eventually possess three average or better offerings, including a fastball that currently touches the mid-90s. He’s not flashy but Keller has 112 strikeouts in 107.1 innings and does a nice job of keeping the ball in the park. He also has a strong frame that suggests he could develop into an innings-eater in the middle of the Pirates rotation. The club has some depth in the big league rotation so Keller can move at his own pace and won’t be rushed in this system.
