Bob Pate was drafted by Oakland A's in the 15th round in 1972, in the 2nd round by the Boston Red Sox in 1973 (January), in the 4th round by the Baltimore Orioles in 1973 (June) and in the 1st round by the Detroit Tigers in 1974 but did not sign with any of those clubs. He was next drafted by the Montreal Expos out of Arizona State University in the 4th round (81st overall) of the 1976 MLB Draft. He put up very good batting statistics in the Expos system and was a September call up for the club in 1979 but did not appear in a game. He made his Major League debut for the club in 1980. That season, he hit .256 in 39 At-Bats over 23 games while helping to fill in for an injured Ellis Valentine. In 1981, he was recalled just prior to the players strike and appeared in 8 games for the Expos and made 7 plate appearances. He was idle for a couple of months while the conflict was unsettled and was returned to the minors when an agreement to end the strike was reached. The Expos released Pate after the 1981 season and he signed with the Houston Astros. He spent two seasons in the Astros system to finish his active playing career. Pate probably deserved a better fate if one looks over statistics in AAA. He hit over .320 in 1979, 1980 and 1982, walked more than he struck out and had On Base Percentages in those years between .383 and .442. The Expos had Ron LeFlore, Andre Dawson, Valentine, Tim Raines and Tim Wallach (who had not yet been converted to third base and put up 36 homers in AAA) competing for playing time in the outfield in 1980 and 1981.
Pate wore this Rawlings jersey with the Expos in 1980. It is from the first set of the year and exhibits an updated style the team debuted that season, which most notably featured red and blue sewn-in racing stripes down the sides and shoulders. The team moved to single-color name and numbers from the blue with white trim ones used the two previous seasons. Pate's number 24 is written in the collar as well as the number 150 in a box. Like many Expos jerseys in this time period, Pate's uniform was handed down by the club for use by the team's minor league affiliates and there is evidence that a nameplate was affixed to the back of the jersey at one time to cover Pate's name.
