Junior Guerra and the Great Old Rookie Pitcher
Sometimes very talented position players stall on their way to the majors but stick around until they finally make good on their potential. Other times, slightly less talented position players keep slowly moving up the rungs of the minor-league ladder until they finally get their chance. This latter path marks the one traveled by Ryan Schimpf of the San Diego Padres, who is one of the better old rookies of the last half-century.
On the pitching side, however — especially where starters are concerned — the good old rookie is a more rare commodity. Junior Guerra is one such rookie, though, and the 31-year-old — off the disabled list tonight for the Milwaukee Brewers — is having one of the more remarkable pitching seasons in major-league history.
If you are a fan of either the Milwaukee Brewers or Carson Cistulli, you are likely familiar with Guerra. As to the former, Guerra has pitched very well this season, making 17 starts with a 2.93 ERA (68 ERA-), 3.65 FIP (84 FIP-), and 2.3 WAR on the season. As to the latter, regard:
- In early May 2015, after Guerra’s first 24.2 innings in an MLB organization in half a decade, Cistulli placed Guerra in his Fringe Five, noting that he had been signed by the White Sox out of the Italian league after having also pitched professionally in Spain and Wichita. (He’s pitched in Mexico, too, but after his release by the Mets in 2009, he went six seasons without pitching for an MLB organization).
- Just one day later, so entranced by Guerra’s profile, Cistulli furthered his study of the aging prospect in a post, showing off his mid-90s fastball and devastating splitter in helpful .gif form.
- That season, Guerra appeared not once, not twice, but three more times that year in the Fringe Five, making him one of the most prevalent players in Cistulli’s weekly exercise with his pace only slowed by four relief innings in the majors with the Chicago White Sox, who placed him on waivers at season’s end, when he was picked up by the Milwaukee Brewers.
- To nobody’s surprise, Cistulli then placed Guerra in his Fringe Five earlier this season, and when Guerra made his debut for Milwaukee, Cistulli called it a Jubilee Event.
