Kansas City pitcher Yordano Ventura, whose electric arm and confident demeanor helped lead the Royals to a World Series championship in 2015, died in a car crash in his native Dominican Republic early Sunday. Highway patrol spokesman Jacobo Mateo said Ventura died on a highway leading to the town of Juan Adrian, about 40 miles northwest of Santo Domingo. The Dominican Republic has the second-highest traffic-related death rate in the world — officials there believe alcohol, speed and a blatant disregard for traffic laws are to blame. Moore speaks frequently with Latin American players about dangers of returning home, including driving on the perilous roads. The Royals lowered flags at Kauffman Stadium to half-staff Sunday, and displayed Ventura’s photograph on the large, crown-shaped scoreboard in center field at the ballpark. Kansas City teammates learned the news in a text chain and took to Twitter to share their sorrow. [...] baseman Mike Moustakas also expressed disbelief, tweeting: I love you Ace. The right-hander went 11-12 with a 4.45 ERA last season, and his fiery demeanor was never more evident than when he hit Baltimore’s Manny Machado with a fastball in June to trigger a brawl. Ventura wound up pitching his entire career for the Royals, going 38-31 with a 3.89 ERA in 94 games, including 93 starts. SANTO DOMINGO, Dominican Republic — In a traffic accident separate from the one that killed Kansas City Royals pitcher Yordano Ventura, former major leaguer Andy Marte died early Sunday.
