Guerrero finding his groove with Dash

Now that he's gotten his feet wet in the Carolina League, Jordan Guerrero is making a splash.

The White Sox No. 11 prospect gave up three hits and struck out seven over seven innings Saturday night as Class A Winston-Salem edged Salem, 1-0, at BB&T Ballpark.

Guerrero (4-3) issued just one walk and retired seven of the last eight batters he faced.

"Everything was working tonight -- my changeup, fastball, curveball and slider," he said. "Great game called by Sean O'Connell behind the plate and great defense all-around. My changeup is always the pitch I trust the most, it's my go-to pitch for strikeouts."

The 21-year-old left-hander is in the midst of a strong four-start stretch, having given up five earned runs on 23 hits while fanning 21 over his last 26 innings.

"I've been working on my mechanics, staying back, keeping the ball down. Everything is clicking and everything works," Guerrero said. "I'm just taking it day by day, pitch by pitch and trying to finish strong."

After struggling in his first few starts following a promotion from Class A Kannapolis on June 7, the California native appears to have settled into a groove with the Dash. He's lowered his ERA from 6.75 on June 18 to 4.11.

"That's what I've been working for all season, being promoted," said Guerrero, a 2012 15th-round Draft pick. "Like I said earlier in the season, when the time is right, it was going to happen. Now that I'm here, I'm trying to do all I can to help the team win."

Overall, Guerrero is tied for fourth in the White Sox organization with 10 wins and sports a 3.30 ERA in 21 starts across the two levels.

Michael Ynoa walked one in a hitless eighth and Jefferson Olacio struck out two in a perfect ninth for his first Carolina League save.

Trey Michalczewski, Chicago's No. 6 prospect, drove in the game's only run with a double in the first. He plated Adam Engel, who reached base twice.

Salem starter Ty Buttrey (7-6) -- the Red Sox's No. 16 prospect -- took the hard-luck loss after yielding a run on six hits and a walk with four strikeouts over 6 1/3 innings.
