17. RHP Jose Marte
Current Level: High-A
Acquired: IFA (2015)
Future-Value Grade: 40
Since Tyler Beede no longer has prospect eligibility, Marte now has the best stuff of any starter in the San Francisco Giants system, provided everything is clicking.
That last part is important. Gregory Santos and Logan Webb are both able to throw their best pitches consistently, which hasn’t always been the case with Marte.
His fastball has touched 98 mph and often sits 94-96, but he’s also been down in the 88-94 range in some starts. He gets great extension in his delivery and generates a lot of sink with his fastball, helping it play up from its already plus velocity. At times, he has feel for a changeup and slider, but both come and go as well.
Best-case scenario, Marte has a potential three-pitch mix that could feature a 65-grade fastball, 55-grade changeup, and 50-grade slider. However, he has a long way to go before reaching that ceiling.
In a lot of ways, Marte is similar to fellow prospect Melvin Adon. Both have incredible stuff but didn’t have the production to match the prestige. Marte has a better chance to stick as a starter than Adon, but his stuff isn’t quite as good.
Marte missed time with an injury in 2019, but he’s made positive strides when healthy. His 5.96 ERA is largely a byproduct of a .415 BABIP and 69.0 LOB%. He’s striking out nearly 30 percent of the batters he faces while maintaining a respectable 3.9 BB/9 walk rate.
Obviously, his control and command need to continue to develop, but his stuff is starting to consistently appear in starts and I expect him to have a strong second half.
