Pedro didn’t pitch too badly at his first minor league stop in the Pioneer League. He compiled an 8-3 win loss record with a 3.82 ERA in 14 starts. He had a decent strikeout rate with 82 strikeouts in 77 innings. Pedro was still honing his control, though, as he walked 40 in those 77 innings. It’s not a bad performance, in any case. However, he was actually out-pitched by lefty Mark Mimbs. Who? Yeah, exactly. (Although, Mimbs actually did pitch for the Pawtucket Red Sox in 1997, so that is an interesting Red Sox connection, I guess…)
There was a time where these 1990 Sport Pro Great Falls cards held a lot more value. But, in June 2019, one PSA 10 example of the Great Falls Pedro Martinez card sold for just $25. You can grab a PSA 9 copy for under $15, but why wouldn’t you just want a 10? There are 901 PSA 9 copies VS 545 PSA 10 copies. They aren’t exceptionally rare. Still, this is a must have card for any Pedro Martinez rookie card collection.
