The Pittsburgh Pirates will unleash one of baseball's most promising prospects as former No. 1 pick Gerrit Cole takes the mound on Tuesday night against the San Francisco Giants.

Here's a look at some of the key stats to know about tonight's matchup.

The History
Cole is the third pitcher to be drafted No. 1 overall by the Pirates (Kris Benson and Bryan Bullington). No other team has drafted more than one pitcher No. 1 overall.

Bullington rates as one of the least successful No. 1 picks ever. Of the No. 1 overall picks to reach the majors prior to Cole, Bullington has the fewest big-league wins (1).

The Pirates haven’t had a starting pitcher win his major-league debut since Paul Maholm against the Milwaukee Brewers in in 2005. The last nine Pirates starters to make their debut are a combined 0-4 with five no-decisions. The nine-start streak is the longest for any team.

Maholm is the only one to win since the start of the 2002 season.
