As I'm finding out, their first names/birthdays don't always correlate with the name on baseball-reference.com. I'm not working that hard if I don't find a match, so I probably will screw up a few of these.
28 - Eddy Diaz / Marcos Manrique
Diaz -played 16 games for Milwaukee in 1997.
Manrique - four minor league seasons; baseball-reference lists him as "Marco".
29 - Melvin Mora / Ifrain Linares
Mora - the birthday doesn't match, but being signed by Houston in 1990 and his hometown match the well-known player; 1,503 career hits; two-time all-star
Linares - cannot find him on baseball-reference.com; card mentions Cincinnati Reds; maybe he goes by another first name but I don't feel like checking the list to match him up
30 - Melchor Pacheco / Leonaldo Olivero
Pacheco - "Alex" pitched in five games for Montreal in 1996
Olivero - four seasons in the minors
31 - Oscar Henriquez / Jean Morillo
Henriquez - pitched in three seasons; 49 games; 1 win and two saves
Morillo - cannot find him on baseball-reference.com; card mentions team - Leones de Caracas
32 - Juan Fco. Castillo / Pedro Belmonte
Castillo - cannot find him on baseball-reference.com; card mentions team - Boston Red Sox
Belmonte - three seasons in the minors
33 - Jose Fco. Malave / Hector Ugueto
Malave - two seasons with Boston; 4 homers in 49 games
Ugueto - six seasons in the minors
34 - Alejandro Freire / Luis Colmenares
Freire - played 25 games in 2005 for Baltimore; hit one homer
Colmenares - seven years in the minors
35 - Jorge Velandia / Andres Espinoza
Velandia - eight MLB seasons; two homers in 174 games;
Espinoza - two seasons in the minors
36 - Edgar Caceres / Carlos Alvarez
Caceres - played 55 games with the 1995 Royals; one HR
Alvarez - two seasons in the minors.
Maybe in the future I will check out the guys with 1 - 2 career wins, homers, etc. Maybe they hit the homer or a HOF pitcher? Most likely they hit it off Jamie Moyer.
