The Dodgers are going young with the call up of 19-year old pitcher Julio Urias who is scheduled to make his MLB debut tomorrow night. Urias will be the youngest Dodgers pitcher since Dick Calmus in 1963. After going 4-1 with a 1.10 ERA and 44Ks in 41 IP at Triple-A OKC the Dodgers feel that it is time to bring him up and give him his first start in the big leagues. It is expected that to control his inning count he will be moved to the bullpen after his start.
If you are looking to get in on the ground floor with Urias you are about three years too late, besides minor league sets his 2013 Bowman Sterling have been selling well and over the past few months have increased in price significantly. Along with his Topps cards both Panini and Leaf have jumped on the opportunity with the young prospect so there are some options.
I do not own this 2013 Bowman Sterling autograph; this image was pulled from eBay.
As a side note, the youngest MLB pitcher was Joe Nuxhall who appeared for the Cincinnati Reds on June 10, 1944 at the age of 15 years, 316 days old. Nuxhall played 16 years in the majors, mostly for the Reds, and retired with a 135-117 record with 19 saves, 3.90 ERA, 1372 Ks in 2302.2 IPs.
