Happy birthday to new Rangers hitting coach Scott Coolbaugh, who turns 45 today.
Coolbaugh is a former Texas Ranger draft pick, selected in the third round out of the University of Texas in the 1987 draft, part of a Ranger draft class that included Brian Bohanon, Bill Haselman, Mark Petkovsek, Terry Matthews, Tony Scruggs, Kevin Belcher, and a hard throwing high schooler named Robb Nen that the Rangers took a flyer on in the 32nd round.
Coolbaugh advanced through the minors quickly, making his major league debut in 1989, but he struggled with the bat and was battling incumbent Steve Buechele and up-and-coming prospect Dean Palmer for the right to be the third baseman going forward. The Rangers ended up dealing him after the 1990 season to San Diego in exchange for catcher Mark Parent, who promptly tore his ACL and ended up never playing for the Rangers.*
Update -- Mark Parent actually appeared in three games and had one plate appearance. I was working off of my memory. Sorry for the bad info.
Coolbaugh went on to have brief stints in the majors with the Padres and the St. Louis Cardinals, before retiring and entering the coaching ranks.
