Navarro, 25, gets his first major league call. The Venezuela native signed with Chicago as an amateur free agent late, beginning his professional career at age 20. (Most Latin American amateurs sign at 16). Predictably, Navarro didn’t generate much prospect attention given his late-blooming background. He combined for a 3.64 ERA in 54 1/3 innings between High-A and Double-A last season to put himself somewhat on the radar.
Eric Longenhagen of FanGraphs named him an honorable mention on his write-up of the Sox’s farm system last winter, pointing to a traditional sinker/slider combination. Navarro has indeed racked up plenty of grounders between the top two minor league levels this year, including a 60% grounder rate in 34 1/3 Triple-A frames. That has contributed to a reasonable 4.19 ERA despite a below-average 21.2% strikeout percentage and particularly alarming 16% walk rate.
Clevinger is back after a six-week absence due to biceps inflammation. He’ll take the ball this evening against the Guardians in what’ll be his last start before Tuesday’s trade deadline. It’s not much time to drum up interest, though it stands to reason some other clubs will send evaluators to keep an eye on his form. There’s little reason for the White Sox to hold Clevinger past the deadline if they can find a trade partner.
The righty has a 3.88 ERA over 12 starts, though his 19.3% strikeout percentage and 9.3% walk rate are each a bit worse than average. Clevinger’s average fastball velocity was above 94 MPH before the injury, but his 9.2% swinging strike percentage was the lowest of his career. Clevinger is owed around $2.8MM in salary through season’s end. That’s a reasonable amount, but he’ll also be due a $4MM buyout on next year’s mutual option at the start of the offseason, which could be the biggest impediment to a trade.
Marcos Grunfeld of El Emergente first reported Navarro’s call-up last night.
